7900XTX Hotspot Temperature Issue tested

One thing I want to add: the previous owner used his card vertically! Because a lot are drawing quick conclusions that "it's only because it was not used horizontally". It doesn't seem to be this simple :) I organized two more completely stock cards today and will do a follow up with more testing soon - including different positions.

For me, the issue only becomes visible once I unlock the powerlimit from 350 to 400W. Before that, the delta is quite big (30°C) with junction in the 90s but after that, it can go from 60-70°C edge temps to nearly 50°C delta with 110°C junction temps that cause throttling. This is a card in Hamburg, Germany. Could get that one to you - but I think it'd be better to find a card that shows a bigger delta out of the box.

This. Someone on reddit claims the temps are normal if he lays his PC case on its side, but if his case is upright the problem returns. I imagine der8auer is using a test bench instead of a normal PC chasis, which might explain why he didn't have the issue his friend did with the card.

I agree, it could be a horizontal bending issue. And there could be a high temperature in the user's case. I didn't see the GPU temperature from the user when the hot spot comes to 109 degrees.

If 7900xtx has the anti-gravity heat pipes then the difference should be a few degrees C, if not probably >20 C. But it shouldn't change the delta too much between GPU vs GPU hotspot

[@Long-do1vj]

The problem was completely missed in the video. I have tested my reference rx 7900 xtx and have observed that following: Traditional orientation (horizontal with fans facing down) yields hotspot temperature of 110 C Vertical mount (like shown in the video) the hotspot temps range between 80 C to 90 C After testing and verifying these results, I performed an additional test where I took off the backplate to tighten all the mounting screws. Most of the screws were already sufficiently tight, but some had a tiny bit more turning capacity by hand. The results after hand tightening the screws were the same, with the horizontal mounting orientation yielding major temperature issues. The mounting orientation yielding such drastically different results means that the problem is either with bad mounting pressure on some units or bad vapor chamber on some units. I would love to see more thorough investigations as to why mounting orientation is causing this issue and what can be done to fix this issue, other than vertically mounting the GPU, which is not possible in most PC cases without modification. Please consider these recommendations and I really hope to see another video update from you regarding this topic.

I decided to repaste for fun with kryonaut (not extreme) and it maybe lowered both temps by 1 to 2c, so the stock paste and mount was actually perfectly fine.

[@CreamyI3eaver]

My 5700xt strix displayed similar temps, turned out the thermal pad on the fets was a whole 1mm to thin so the screw heads made no contact to the back of the pcb, simply folded the pad and it dropped junction temps from around 108 to high 80’s.

[@opinali]

This is unfortunate because the cooling solution including the paste used on the die is superior to what they used in the previous gen (check GamersNexus's teardown review); however, you can have all sorts of problems in the assembly line. These should be caught in QA test but obviously, they weren't.

[@Pulverrostmannen]

I could guess the issue might come from the squishy pads on the memory chips that could possibly affect the pressure on the GPU die, now when they been opened and messed around with they probably been flattened more and the pressure on the die probably increased again

[@SianaGearz]

@@humorss Well there are, there's the shader cores with separate ALUs for different kinds of arithmetic operations, and of course even in one multipurpose ALU, all operations don't hit the same exact semiconductors, and around them there's TMU (texture fetch), memory/scheduling (because memory fetch often forces latency hiding logic to swap tasks), and ROP. And that not even counting the new RT hardware. When you read utilisation, it just takes the max of all values per SM, and any operation in an ALU is considered as that ALU being utilised, in spite of some being potentially more power hungry than others. Typically, ROPs are severely underutilised in most of the render passes.

High hotspot temp could mean the chip is not fully covered in thermal paste. Bad news if the die has no heat spreader. Heard of this happening on nvidia gpus as well and that it affects some amd 6000 series as well.

[@TheFather_]

The orientation of GPU is important as well, if its a test bed, then most probably you wont see a problem, people reported that tilting the case to its side like a test bed results in lower junction temp, so if you are doing it on a test bed, then just try installing the card horizontally (fans facing down) and the case sitting vertically like a normal PC and then retest on new affected card since the one you have already got fixed by re-applying thermal paste and balancing the pressure.

[@sonicboy678]

I was also thinking about whether it was in a case or on a test bench, which is usually -- if not always -- open-air. That, combined with the orientation, will definitely impact the air flow.

[@drupiROM]

I personally owned a single fan gigabyte gtx 970, it was running 60C in the mobo and 88C in the vertical GPU bracket, that was when i found out about this issue, it was easily reproducable by tilting the case on its back or face. Vertical bad temp horizontal good temp

[@anteck7goat]

I’ve got data on this. Orientation creates a higher temp delta. It’s crazy. Test bench style mounting is okay Normal case mounting causes 110 Celsius junction temp.

You people keep saying orientation matters but Roman already commented in this comment section saying he has tried both orientations and it is irrelevant.

I was re-pasting my 2 y old 6900xt yesterday because hot spot was reaching 105* C but GPU temp was never above 64* C after doing this the hot spot temp stops at 82* C but the GPU temp goes up to 71* C I was surprised because the original paste looked good and was still quite soft

[@DigitalJedi]

The reason for the higher GPU temp might be that the heat is more spread out now, rather than sitting just within that hotspot.

[@SianaGearz]

@@DigitalJedi Nah it's because the card before repaste hit the tjmax at hotspot so it would clock down. Higher temperature in this case means more performance due to higher amount of workload being performed.

[@dra6o0n]

When you RMA a GPU and they test it, they will most likely position the GPU vertically as the testing board they use it on will be flat on a table... This also means they don't notice any problems that you would see if the GPU is installed horizontally in a case.

[@MrHeHim]

air pocket? I've noticed it near impossible to see signs of one after you pull the heatsink as it suctions away any traces, unless the thermal paste is old enough to leave a bubble mark. I always make an 'X' with a little extra in the middle to ensure the air gets pushed out. With Liquid Metal i put an even coat just enough to cover the surfaces with surface tension then a little extra on the middle of the GPU/CPU and the middle of the heatsink. Over time the air pockets might pop and temps will go to normal, but that can take weeks of temperature fluctuation to work itself out

But within 3wks temps went up 10C on the gpu and hotspot was in the high 90's. After a week of temps hitting 100C, I took it apart and repaste the gpu with Kryonaut, temps dropped back to what I saw in the beginning. But yet again 2-3 wks later temps rose back to high 90's on the hotspot. I repasted again but with IC Diamond. It had appeared to me that the Kryonaut had been squeezed out. IC Diamond is a thick TIM. This fixed the issue for the last 3 months. I didn't have this issue with my cpu and Kryonaut. I guess it's just luck of the draw.

[@Fezzy976]

IC Diamond shouldn't really be used for GPU's or CPU direct die. As GPU's don't have a heatspreader and you are putting the paste directly onto the die it self. IC Diamond is just that, it has diamond particles inside it meaning it can scratch the die surface and MAYBE damage it over time.

[@thanatoast4]

I've had a Nitro+ Vega 64 for 4 years now and have been dealing with this issue the whole time to varying degrees. I've used kryonaut for the entire time due to it being a very thick paste, but switched to Gelid GC Extreme just recently and it's been the same. Would always be the same story - repaste, then watch hotspot delta start to run away as the weeks go by and paste is "pumped" out from thermal cycles. (granted, it was never so bad on my card, just something I noticed). At stock settings temps were never an issue, but raising vega's anemic power limit also increased the hotspot delta disproportionately compared to edge temperature. Following the Vega specific hotspot/repasting guide from Igors Lab helped a ton - use thick paste, spread manually, followed by specific screw tightening order. But what helped even more was taking the cooler BACK OFF not long after repasting, observing how the paste had spread, and then re-applying the SAME paste (and potentially adding a little bit more if needed). It took me many attempts to finally figure out what works best, and temps have been great ever since. Along with deshrouding and mounting NF-A12x25's to the card, temps have been a complete non issue even running lots of voltage, though I run the card daily with a heavy undervolt. At 1.2v + 360w power limit on furmark, the card now has an edge/hotspot delta of only 20c, which is remarkable considering its 120w over stock. At the same settings but with a bad mount and stock fans at 100%, the card would eventually hit temp limit and shut down.

In my setup, my MBA 7900XTX has no problem at stock at staying cool in very stressing games like e.g. Metro Exodus: EE. However the second I touch the power limit, the hotspot temp jumps up dramatically and maxing out fans doesn't seem to do much to help. In Exodus specifically, setting the power limit to +7% gets me in the mid 90s on junction and 10% makes it slowly rise up to 60c/110c (50 degree delta!). Bought some PTM7950/Gelid pads for the backplate to see if things can be improved. Maybe past ~370w the vapor chamber hits dryout (if that's something that can even happen)?

Soft power play table might be messed up for the PL on the GPU, the power scaling going out of control when it is turned up may mean it's misconfigured in the bios?

[@AshtonCoolman]

Is GPU sag from horizontal mounting vs vertical mounting a factor? Also were the screws possibly not torqued enough? It seems like either disassembling and reassembling the card or mounting it vertically corrected the problem.

[@HDJess]

I haven't heard of it being a problem, those screws are made to be torqued until they hit a stop and not force further, the torque is given by the metal bracket (spring). The card can't be easily influenced by sagging as it's got many screws which keep it from flexing, especially with the help of the backplate. Most of the visible sagging would come from the PCIE slot itself plus a little bit from the edge of the PCB which inserts into the PCIE slot, but that little bending there is just local and doesn't reach the GPU area. In this case, I would just assume the owner either mounted it incorrectly or used a bad TIM or didn't clean the chip well enough before reapplying TIM. Also, the issue might not manifest with normal PL in place, might need to give it maximum power to see bigger Deltas.

[@nommindymple6241]

On the AMD forums (I can't provide actual links because KZbin deletes my posts if I do), one person tested his card in four orientations (look for "7900xtx reference orientation testing. Orientation impacts performance"). The bad temperatures show up when the card is a "normal" orientation (i.e., when the card is horizontal). In a "test-bed" orientation (when the card is vertical as with your setup), the temperatures are fine. Try tipping your test-bed on its side or putting the card in a regular, tower-type case.

[@eugkra33]

Maybe it's the order you put the screws in. Maybe a certain order it bends the PCB.

[@2LOLHAHA]

I’ve just put my Powercolor 7900 XTC MBA in my Pc and ran kombustor. After 1 minute my junction temp hits 110 Celsius and the GPU is at 59 Celsius. Even with fans at 100% it takes 2 minutes to get to the 110 Celsius junction temperature!

[@ChadKenova]

One thing that many people think is that in a vertical mount in a test bench it’s fine but mounting it horizontally in a pc the cooler pulls away from the pcb and die slightly. I need to finish the video before I comment i see you talked about this issue above but i will watch it all love your content.

[@headlesschickenfarm]

The question I would like answered is what refresh rate the monitors were using as just about every reviewer is making a mess out of this.

[@teknorakun]

I think that might be becuse of the vapor chamber, if there is a kind of over pressure thing and if because that heat transfer with pipes or die starts to goes away this behavior can be happen, and the score issue with ASRock card possibly because of VRAM frequency.

[@jimbodee4043]

Wow no issues after you touched it. :D

[@pdamasco]

Honestly that's the best case scenario. If anything AMD can send out some free thermal paste and post a video about how to disassemble the card and properly re-paste it. If people don't want to wait they can say you're welcome to re-apply paste on your own and we won't void the warranty. Not nearly as bad as the difficult to clip in 12/16 pin connectors.

[@dra6o0n]

Some people bought new PSU where 12 pin to two 8 pin connectors are given to them... i wonder if the 12 pin slots on the PSU outputs different wattage than normal 8 pin slots.

[@otakarkratochvil939]

Hello. I also have a 7900XTX XFX Merc 310 card, the hot spot cannot even be cooled with a water cooler. The temperature of the hot spot was still around 110 degrees and I did what I could (various thermally conductive pastes, tapes, etc.). I'm quite stressed about it, because the card doesn't cost a lot of money. I would also like to point out that there are of course different temperatures in full HD, 2K and 4K at certain Hz, where 60Hz will have low temperatures. Where, of course, the high temperatures are resolved at 144 Hz in 4K! That's pretty important! ​

[@Cblan1224]

How long was the card stressed? If they're using phase change material like the honeywell pads, temps will be higher than normal for around the first 24 hours of use.

[@dimwillow7113]

if you want more info.. my ref 6900 xt has the opposite orientation problem.. i have silverstone fortress 2 which have 90 degre rotate motherboard..so the gpu hangs straight down..vertical.. my hot spot was crap 110++.. then i remember certain vapor chambers 10 years ago had problem with orientation so i just tipped the case on its side(gpu sits horizontal) and hot spot temps are no longer a problem..

[@Zensaitv]

Hmm if it's normal now maybe there are air pocket in the OEM application in the thermal paste? that's what it sounds like to me I have had this happen to me before but never know could be anything

[@SianaGearz]

That really shouldn't be happening, because at the factory they don't just put the dot in the middle and press down like good luck, they stencil it on exactly, covering the whole area and depositing the engineered amount, this method automates well and produces repeatable results, with spot quality assurance being able to determine issues and pull a batch of cards to be reworked before the cards are ever shipped out, and the QA is in a feedback loop with engineering. And after all, the customer reapplied paste and it looked well spread and still didn't do the thing? But possible? Remotely? Yeah i guess. More likely something subtly wrong with the coolers themselves, surface flatness or something.

[@user-el4np5xt8c]

I have the issue, repasted and its fine in stock settings, however if I run timespy with any added power it slowly ramps up to 40-50° delta. try adjusting power to max and rerun timespy, thats how I simulate it. I repasted with noctua nt H2

[@DS-pk4eh]

I still do not know if ALL OEMs have the same problem with AMD reference design or is it just some of them?

[@nebulaexe]

My XFX 7900XTX reference (horizontal) would reach 110C hotspot within 6 minutes~ of running furmark. I did open it up to repaste with MX4 and did torque the screws as far as they would go by hand but unfortunately my temperature issue persisted. I did test vertical mount by flipping my case over and it did definitely have dramatically better results. At this point I don't know what to do besides a RMA since I plan to use the gpu horizontally. Also when repasting I noticed the stock thermal paste was very solid, best way I would describe the consistency is very old and worn out thermal paste.

[@arahimakzar]

It's almost as if the card is designed to reach 110c.

If you play a game, it probably won't be that hot, it's because you are stress testing it.

[@d4rtarius]

I had the same issue with my card. It would reach 110C and I guess it must have went further because it happens two times where my PC completely shutdown to protect the card. I was running the 22.12.1 drivers. Then, they released 22.12.2 and everything seems to be back to normal now with deltas similar to what you have. However, something tells me that probably the thermal paste and pads need to be changed, maybe the pressure if not good enough; comparing my 3dmark results with people who have the same CPU, I found my results to be quite low in the area of 21500-22000 (OC) whereas some people have been getting 27000-29000. If I don't OC the card, the results are even lower, around 19000. Not sure what is going on.

[@WilliamVG]

Sorry to hear about your card, looks like the new drivers lowered your gpu clock speed, not good.

[@Rentta]

Io-tech just tested and they got 7 - 9c drop after installing card vertically. New paste and remounting didn't do much for them.

[@BaldyMacbeard]

This card has some serious issues. Mine was running hot at 110 junc with a bad dp cable. Swapped cable - temps went down 20°. Tore the PC apart few days later. Again - 110°.. Guess what? Different temps depending on which displayport port you connect to. I can imagine that you didn't fix anything but rather don't encounter the problem because of some fluke. Interaction with display or whatsnot

[@763762russian]

could there be a difference between your mounting pressure and his

[@Fezzy976]

I had 107C hotspot and around 65-70C on normal temps on my Sapphire MBA card. I have since undervolted from 1150mV to 1120mV and locked core to 2400 min 2500 max +15 pwr and 2714 VRAM. With a custom fan curve I now have temps in the region of 55-62C and 70-85C hotspot. I didn't disasemble the cooler at all. I believe this is due to the phase change TIM used on these cards. I don't think AMD properly baked them in during testing. I am sure this TIM has a rather long cure time so people are buying these cards and seeing huge delta differences and getting scared. But I think after a few days or a week you will see these temps drop off and this delta get smaller and smaller.

[@realbeetlejuice]

so I should wait to receive my sapphire ref 7900xtx and not panic?

[@phenos]

If the manufacturer from the coolers use Honeywell PTM7950SP solvent based screen printing phase change paste then it needs at least 15 hours of curing time at room temperature before the heatsink gets attached. The process can be accelerated by using a forced air oven at 50'c for 4,5 hours. Devices equiped with Phase change material need some thermal cycles to achieve it's full potential.

[@Fezzy976]

@@realbeetlejuice I wouldn't panic at all, just make sure to run some tests and see if you model has a problem. But new drivers have been excellent and fixed a number of issues already. Repasting GPU is an option but not really needed, and undervolting seems to be the way to go. I would stress though synthetic benchmarks like 3DMark for me run and pass at 1065mV but a lot of games just outright crash after a few mins. So tweak your voltages.

[@Fezzy976]

@@phenos Very interesting, thank you for the info. I thought it had some cure time involved.

[@phenos]

@@Fezzy976 The "mistake" many people make is by replacing the factory paste with low viscosity (high silicone content) easy appliable paste like MX4 or NT-H1 because it's so good on all those 1st day temperatures on KZbin reviews but what is not taken onto part is the holdup time. Modern age direct-die devices with high turbo speeds and the temperatures that come with it degrade many pastes very fast due to silicone separation or pump-out on uneven surfaces.

[@ChinchillaBONK]

Is it possible to do tutorials on how to disassemble and reassemble and the other things you mentioned to do for the card? Hope it's not a hassle.

[@StopaskingformynameYouTube]

I have the same issue on an Asus rog strix 3070ti, i had to open it up, apply some new thermal pads and more thermal paste to fix the issue bechause Asus has bad quality assurance, so the pads wasn't aligned properly. On that card the issue was one of the VRMs being allmost without contact to the headspreader.

[@MrBobbybrady]

Just out of curiosity, how many watt power supply are you using in your test vs the original owner? I'm curious if you had a weaker power supply if the current would raise if the voltage sagged causing additional heat on the card. I caught on to the owners second card didnt have the same issue, but it still makes me curious.

[@mamawakikawasaki]

I had issues with high overal temps with hotspot reaching 110C on my rx 6700xt pulse. I even bought morpheus cooler but when I wanted to install it ive realised the standoffs are too long so i packed it back and now the temps are much better with stock cooler. Apparently it was just badly mounted and reseating fixed it. Also ive first screwed cooler to card, gpu core bracket was last to screw in.

[@mamawakikawasaki]

TLDR: Outer screws first then springs worked for me

[@luisolivas3401]

Just opened mine today, re mounted, paste it came with is almost completely dry and poorly spread. Left as is to see if simply remounting would make a difference, it did not. Buying thermal paste tomorrow to re test and getting a vertical mount to try that after. I will update once done. Update: bought some Kryonaut thermal paste, re mounted and pasted thoroughly. It seems to have made a difference at first but after about an hour or so of heavy gaming, it peaked at 110c again. It seems to be a bit better since its no longer constantly at 110c, it oscilates anywhere between low 80s all the way up to 110. Pretty strange behavior. Any ideas for other things to try, if anything?

[@konradmajewski7032]

Just out of curiousity. What model do you have ? Do you somehow managed to lower temps ?

[@luisolivas3401]

It was the power color reference model. It did not work, repasting was a very temporary "fix". Sent it back, got it replaced by another reference model and it came with the same issue. It is now in the process of being replaced by a Hellhound version. Hopefully this one doesn't have the same issue.

[@saniwada]

I have a reference asus 7900xtx and have had 40*c delta's in cyberpunk. I tried reproducing the issue in furmark but only saw a max temp of 90*C in furmark. In cyberpunk however after about 20-30 minuets of gaming my card had a 40*c delta and junction temp hit 110*'c with gpu temp at 70*C, when junction temp hit this temperature the card went from a 2500mhz clockspeed to a 2300mhz clockspeed and fans hit 3000 rpm. my card has standard horizontal mounting.

[@Bard_Emancipovani]

How did you apply the thermal paste - did you apply it in the middle in the form of small dots (the classic method), in an X shape as some people do, or did you spread it evenly across the entire surface with a spatula?

[@ASEKen]

Another great video

[@CharlesVanNoland]

Is it really running hot, or is it a bad thermostat being put on these? The vapor chamber test would be to switch coolers from a known good GPU and slap that sucker on a hot GPU. If that fixes it then it's the vapor chambers for sure!

[@SianaGearz]

These are on-die temperature sensors, so there isn't anything to "put on" particularly that would cause the malfunction. Is it possible that the designed-in temperature diodes or sensing logic has some sort of a defect? I don't see how it would pass validation to begin with then, or how there isn't more damage, but i guess it would be silly to dismiss the possibility out of hand either. But seems exceptionally unlikely to me, more likely something with cooler subassembly.

[@artura5526]

I have the reference one from sapphire, and have the issue - 45deg difference between hot spot and core. Can ship the card if you are interested.

[@dbwmotorsports8695]

Could a solution be to just loosen all the mounting screws and spring plate and then retighten them starting with the GPU?

[@opinali]

I got lucky with my 7900 XTX, great temps, but previously I had trouble with my 6800 XT (both AMD reference) which was initially good but started failing after 3 months. I realized that the fans wouldn't spin any faster than the minimum speed so the card overheated and shut down. After disassembling, thorough cleaning & re-pasting, it was perfect, never had problems again. That card used a graphite compression thermal pad so bad spread is not a possible problem (I put in a new IC Graphite pad). Because of the symptom specifically with the fans, I suppose there were some bad contact problems with the connector or possibly signaling issues in the PCB due to any piece of conductive dirt stuck in the wrong place? (Not a PCB expert, have no idea if that is possible.)

[@Progamer-jv8mb]

When you want to test hot spot only good enough test is in games or superposition bench.I had same issue 110 when card is used up to the max.Manage to drop it to 92 with gryzzly paste, Control game was one of them which was pushing my hot spot to over 110

[@julianvanderkraats408]

No, the thing is that if you pump more watts through it then the default wattage, THEN the delta between the GPU temp and the junction temp starts to grow to an abnormally high number. It's simply a matter of a cooler that is just average. You can easily test this with a game or synthetic test with much higher clocks then you did.

[@anhiirr]

kinda sad to see when the 5700xt came out there were huge thermal issues even mounting issues with cards like the STRIX/TUF models and the reference models had very high VRAM/VRM temps too. Which were co-opted through HP/OMEN and many 5700xt oem cards were sold through that venture as well....many im sure that were never undervolted/tuned to run well that are now at 2-3 years old on their last leg...barely running at 1900mhz.

@@sirmonkey1985 I have the card in a case, not a open air test bench. This is not a blower style card, which means all of the heat escapes from the sides of the card into the case. Case fans can only help so much, especially if the side panel door is closed.

[@MLee-vcrr]

@@kucing1087 You are correct in this scenario because the test is on a open air test bench, not inside a case. The backplate can make a significant difference for cooling if used with thermal pads as a heat sink. This card does not do that. Mounted in a case, the backplate is more of a "heat trap" than a heat sink because of the design AMD chose.
