Please don't do this - AliExpress GPU Backplate Cooling

[@alexz1232]

GDDR modules distribute most of their heat into the PCB itself through the copper traces. It would make the most sense to test backplate coolers by looking at VRAM temp, especially with additional thermal pads bridging backplate and PCB.

[@DragonOfTheMortalKombat]

Thanks for telling, I have some old heat sinks and thermal pads that I'll attach at the back of PCB now.

[@seeibe]

Well, the amount of heat dissipated also depends on the thermal differential. When you go VRAM -> PCB -> thermal pads -> small backplate cooler, I suspect much less heat can be transferred than going VRAM -> thermal pads -> massive front cooler. So yeah, in theory more heat may be distributed into the PCB itself, in practice thanks to cooling I suspect more heat will be dissipated through the thermal pads on the front. But would be interesting to validate this.

[@onlyeyeno]

@@seeibe Yea, unless You have a 3090 which has half of it's VRAM on the back, in that case it just might ""work"". Then again if You have a 3090 I really don't think You should try to cool it by "strapping random scrap metal" onto it with with zip-ties :) Best regards.

[@z33thr33]

I set an old AM3 stock cooler on top of my 2080 TI with some thermal pads in addition to the normal cooling solution and got -6c average gains as shown in CPUID HWMONITOR without even replacing old pads yet. My solution, however, is the exact size of the hotspot on the backplate, not the size of half of the gpu like this thing in the video

[@MrBalrogos]

Yeah i got RX 6800 XT and i put thermal pads and cut plastic insulation from backplate and i use thermal pads on the side where vrm is :) and temps drops nicely

[@falcie7743]

When I had a 3090 I did a DIY solution like this with a giant aluminum heatsink and an 80mm fan. It actually helped in my case, because I was thermal throttling due to memory temps, even after replacing thermal pads. At least I was able to keep the memory at about 95C instead of 112C.

Yeah I wish he would have tested with the 3080/3090 because the backplate really helps the mem temps on those cards.

[@LordSaliss]

Same. I watercooled the GPU and found that backside memory temps were keeping everything throttled so had to add cooling to the back. I got a replacement back plate (so I had a spare) with a pair of RAM waterblocks that I thermal epoxy'ed to the new backplate. The waterblocks on the back really helped cool the memory temps by keeping them 25-30 degrees cooler.

[@gex581990]

My 3090 has 65c-70c mem temps and I even have the mem overclocked to 3090ti spec. I simply changed the pads to higher quality ones just a teeny bit thicker, put a Asus ROG 120mm fan (that has a amazing balance of airflow and pressure) onto the backplate pulling hot air out straight into my case’s rear exhaust fan. I was able to drop vram temps without even affecting the core temps negatively

[@SmarterGaming]

It would have been fun to see you rig a regular 120mm case fan blowing directly on the back plate, maybe with a 3d printed bracket or even just some rubber spacers and see how that would have worked compared to the Aliexpress versions.

[@markh-vy1sl]

That's exactly was first thought. This is only for 3090. There is even a liquid cooled backplate cooler for 3090. The memory chips on the back were a huge problem for 3090 and they fixed it in 3090 Ti.

[@bfbunny]

​@@bleedsblue0023 Well, yeah, a 3080ti can benefit from such a cooler, but people have been reporting drops of mem temp from 100+ degrees to a little above 80 with a 3090.

[@skryzskruzzle]

Attaching a heatsink to the backside of the PCB where my VRAM was allowed me to OC from +1000 to +1250 for benchmarking. Core temperature was still the same however, and once the heatsink at the back got heat saturated, +1250 would crash also.

[@BBWahoo]

Damn you heat saturation, damn you!!!!!!!

[@giaopx]

can you just add a fan to it?

[@skryzskruzzle]

@@giaopx Yeah I could, but from the limited testing I did it would just extend the time that I was able to run +1250 OC on VRAM, but it would still become unstable after long enough.

[@granolafunk6192]

I just rested a server CPU passive heatsink on the back of my 3080ti and got almost 5C off the memory temps. I was going to thermal paste it but ended up putting better thermal strips on it.

[@rustler08]

And this is why you don't waste money on silly solutions like that and instead just watercool when you want to push OC limits

[@CossackHD]

Would be interesting to see difference with just a 80mm fan placed on its side on top of the card, blowing along the backplate from power connectors in the direction of the IO plate. I'm pretty sure that would be about as good as the 50 EUR thing or perhaps better.

[@SilkMilkJilk]

Î would bet my money that your assumption is correct, the fan alone would be better^^

[@teardowndan5364]

Do the same thing but after removing the backplate. My bet is that no backplate will perform slightly better since the bare PCB has more surface area since you have have all of the SMD perimeters that lose airflow when you slap a backplate on, SMDs sink most of their heat into the PCB and skips the thermal pad resistance.

[@SlappySlapperman]

Used to do that all the time, would put plastic motherboard standoff's in the screw holes and set it right above the back of the GPU..

[@hectorj.romanp.]

I don't know about a backplate but for an HDD it works pretty well; mine dropped from 50 C to 40 C moving it from the bottom of the case to a middle bay where it gets the air of the front fan of the case.

[@mtx33]

@@teardowndan5364 Honestly I'm not sure about removing the backplate from gpu-s which using thermal pads between the board and backplate.

[@Coloss03]

I got -10 degrees from mem temp on my 3090 during mining using the cooler #2.

[@Kommunisator]

This kind of cooling can lead to interesting problems. I built an ITX rig for a friend once where a 200mm top fan blew onto the back of the graphics card. The PC was always crashing when gaming, because the temp sensor of the GFX card was cooled too, and didn't spin up its fans. As a result, the GPU actually overheated, although the back of the card was cold to the touch ^^

[@dumdum93]

You should've tested with a 3090 because that's the only card in need of backplate cooling.

[@themartinc123]

I think der8auer missed the mark on this one, a 400W GPU is going to hit the RAM and VRM much harder than the 270W class GPU

[@rustler08]

That's only applicable to cards that have those components on the back or have thermal paste which transfers the heat from them to the backplate.

[@Revener666]

Just get a little bit more airflow in the case if you have issues........ Or if you are going to use zip tids anyway, do what I did in my spare computer to cool a part of the motherboard that got hot and rebooted me. Hang a fan with zip ties for directed airflow, it does alot. :)

[@angrydragonslayer]

I tried compressed air and it did wonders

[@kennethmei]

I used to use my 3090 for crypto mining when I was not using it. The back-mounted VRAM was constantly getting way too hot and it would hinder performance a lot and could not reach its normal hash rate. I installed a backplate cooling solution and it worked perfectly. In normal gaming applications though, it would have never gotten hot enough to warrant having a backplate cooler.

[@rawdez_]

5:50 you can put top ziptie inside the finstack, on top of the fin closest to the card. also you can cut off excess termal pad, it'd look better-ish.

[@wapted]

On a multi RTX 3090 setup I used 1u Server vapour chamber heatsinks on the backplate. It really helped with the insane vram temperatures

[@countfrackula6707]

I had a 3090 that I cooled with a backplate addon. It def helped the memory temps. I took a large heatsink and used thermal adhesive to stick it on, combined with some thermal compound. It def helps if you have memory under the backplate.

[@AnIdiotAboard_]

Free tip when using zip ties to secure things down around square objects. Tennis Balls, Hollow Rubber Balls, and Ping Pong Balls. Cut them in half, in this case it would have been flat line down on backplate, and zip ties over the top, not only toes this allow for serious pressure to be applied, it also EVENLY pushes down into the backplate thanks to natures most stable of shapes. :)

[@tobiasdubiak4747]

You should test mounting a fan directly on the backplate. I guess that would be more efficient. And you can use zip-ties to get the same professional look.

[@cfodderferret]

Clearly rubber bands are the preferred fan mounting solution. Must be for noise damping or something.

[@aahlala]

Could you test with a 3090? I'm wondering how effective it is on the memory temperatures.

I did wonder if a 3090 would have been a better card to test with because of the hot gddr6x VRAM being back-mounted. These products seem to be a response to that , and probably useless for anything else tbh. Gave me a good laugh. Surely having your backplate running hot is a good thing!? means it's dissipating heat I'd have thought.

Correct me if I am wrong (or is not possible) but shouldn't you use the zip ties on the bottom copper layer? You know, the one that is touching the thermal pad. 5:40 That one is touching all the backplate so it would not bend and the zip ties should get more even pressure (assuming you can put the zip times between the copper plates. I cant see if that is possible). EDIT: I heard the price. Nevermind :D.

Yes it would, I got a 3090 & while the memory junction (the hottest module) never really got to dangerous temps there has been a few times I seen it top out around 98/99C (thermal throttling is supposed to start at 110C on GDDR6X modules). Which is a bit too close to the limit for my liking. I put a 120mm Noctua fan with some bumpers to hold it up off the backplate a little on it & have never seen above 92 on my mem junction temp since.

I would say just having a fan from the front blowing air over backplate would be plenty. Also yeah the tie rip stuff is painful...probably why they included thermal glue, and man if that second one was just done more professionally, it would actually be pretty cool imo

RTX 3090 would be perfect to test it, because of double side GDDR6X memory and temperatures like 90 - 100c from the backplate side.

This model of mine actually has a good and very usable aluminium backplate that has a sign "caution hot" but is out of the box completely un-utilized.

Heat from the core, VRMs, etc is in the PCB..: Getting it out (into the air eventually) using cheap thermal pads is a waste of time and money. Just point fans at the hotter areas of the bare PCB. ie: Go directly from PCB to air, skipping the delta T losses of pads and backplates etc. This got me up to the top frequency of one memory strap up on a R9 280X. Hypothosis: Heat from the core and VRMs etc was seeping INTO the RAM modules via their BGAs etc. Ameliorating such allowed the RAM OC quickly, cheaply and effectively and slightly cooled the core aswell.

[@andreyvsjoker]

I have put a 100mm fan on the backplate of my 3090 and it dropped Vram temperature during mining. It was thermal trotteling before and I was able to stabilise it. So it does help.

If I'm ever paying 50€ for a GPU backplate, the least I'm expecting it to have is an RGB-empowered waifu.

[@dreyga2]

2x hotter

[@theguywithajeep]

you installed the zip ties wrong at 6:00, they should go along the protruding edges of that copper cooler, that's why it has those edges sticking out.

[@theguywithajeep]

could also feed the zip tie in between the bottom copper layers like you did though the gpu cooler

[@gamingevolved760]

Best option is undervolting card,than can get 10 degree cooler with 2% less fps

[@sykoteddy]

Damn, this is like a comedy episode. You obviously didn't do anything wrong or bad. I really salute you for buying and checking out these so called products. I know not everyone is as handy, but I would rather go and buy the copper sheets myself and do something with. Regarding the second product, I would so much rather have it unpainted than that shitty "paint job", it hurts even calling it a "paint job", heck, even a toddler would do it better. In my opinion copper is really awesome looking and I could really imagine having a complete water loop with only copper and brass parts. It would look sick as hell!

[@Fractalbreakz]

but is there thermal pads at the backplate of the gpu? if not is a usseles test...

[@rod2508]

Its interesting that noone has just used the existing backplate (with screw holes pre-drilled) as a tempate for making a backplate heatsick? Like something you could literally swap out backplates for that uses thermal pads directly onto the pcb, does not have fins too close to the motherboard but has enough surface area for significant thermal dissipation and perhaps even a version for mounting 80mm slim fans onto. I used the arctic accelero extreme IV and it was an absolte beast for cooling. Was ugly AF but damn was it good for temps (passive temps too)

[@vedo94x82]

Question? Isn't a hot backplate actually a good thing, that heat is being conducted/dissipated through backplate and its not trapped below plate.

[@dreyga2]

No, your backplate is hot because the heat is trapped under it. The backplate cannot dissipate heat fast enough, so the card overheats. You are confusing the backplate with a heat sink. Heat sinks are very close to the part they want to cool and have very thin fins that help it to lose heat faster. The backplate is far away and has no fins.

[@ricardolmendes]

Why not a 3090 which is probably the card that would make more sense to this?

[@iguanac6466]

On that first cooler, might have worked better if you ran the zip-ties just over the base of the cooler and the 1st fin and added a middle zip-tie. On the second solution, it looks like the fan is mounted in the wrong direction so it's fighting against the front fans instead of pulling fresh air over the heatsink.

[@TheEightfoldPath_]

Ive had issues with vram heat on my 3090 lately, evga 3090 with the hybrid kit. Memory temps hit 105. I simply placed a spare case fan on top of the backplate blowing down into the card and now it caps at 90 degrees and my gpu fans no longer go to 100% to bring it back down from boiling.

[@PCgamestech]

Im pretty sure this was designed for a 3090 in mind not an AMD gpu. Because the 3090 got very on on its backplate because the Vram was there. Also my 3090 has so much sag now that it just get hot for everything so I had to change the mount to vertical to keep the pressure off the board.

[@dodgydruid]

I just took a chance on one of them RX580's off Aliexpress, with coupons etc came in at £45ish which I am going to be happy all day long if it runs OK and I know I have to thoroughly clean the thing up and new thermal pasta of course. I was tempted for a few pounds more grabbing a 590 but looking through the seller feedbacks it wasn't positive whereas the one I got my 580 from had all but one positives and the one not positive was a missing edge conn trace and the company sent him a replacement. I am working on building a killer water circuit for mine at the mo, my case is the enormous HAF XM which has room for top and rear rads and was thinking of going 2 rad, with the rear rad sitting between the GPU and CPU blocks and the top rad for max thermal exchanges. My last water build I used the Antec Skeleton which I had painted toxic green with red spatters, a twin circuit rig with one circuit for the gpu/ram/bridges etc and another for the CPU...

[@subjektivegaming]

I was having heating issues on my RX580 playing newer games, all I had do to was reduce some graphic quality options and it holds around 60 degrees. I was honestly contemplating some sort of extra cooling for my GPU but it's not worth it.

[@reptilez13]

Hot backplate = dissipated heat. Solution: don't touch your backplate under full load. 😅 Edit: in all seriousness, i understand adding stuff especially for better GDDR6 temps etc but regular heat sinks or pad between the plate, direct airflow... So many simpler, cheaper and better looking solutions lol

[@wagnonforcolorado]

I appreciate your testing this stuff from Ali Express, so that a bunch of us do not make the mistake of sending our hard earned money away, and getting "recycled" e-waste in return.

[@peyton_uwu]

Maybe a solution like replacing the backplate with one that has machined fins on it that's cooled by the airflow from the front and rear fans, or even strapping a few fans to it. You could also replace the backplate with a heatsink, but at that point the added cost and weight just doesn't make sense compared to, like you said in the video, a GPU waterblock.

[@Voyajer.]

It's always a shame when an expensive GPU with a metal backplate doesn't even have thermal pads to make use of it. (looking at you Powercolor Red Devil 7900xtx)

[@saturnv691]

I would be more interested to see if it has an effect on memory or vrm temps rather than gpu temps especially because some cards do have memory on the back of the pcb

[@FOEChico]

Adding a radiator on the hood because it will help heat soaking problem with my current setup. Great idea for my car, too

[@uncleanon6445]

Why would you add this to the existing backplate and not instead of it???

[@larsjrgensen5975]

From testing on my ASUS Vega 64, thermal pads from VRM to backplate only spread the heat 1 cm out into the back plate from where the thermal pad is located. So even though I connected the VRM to the backplate, the cooling surface was only the size of a DDR5 Memory stick, because the heat did not spread out into the entire backplate.

[@dreyga2]

take your back plate and throw it in the trash where it belongs. Let the card breath.
