7900XTX ASRock Phantom Gaming GPU Repaste with PTM7950 (Hotspot Fixed!)

Doing a repaste on a 7900xtx ASRock Phantom Gaming card. I went with PTM7950 for the sheer performance/cooling along with longevity. A normal thermal paste will over time eventually pump out at least from what I’ve heard. The PTM7950 will completely bypass that making it a long lasting solution while being very safe considering it’s non-conductive unlike some thermal sheets.
What you’ll need if you want to do this:
PTM7950
You can get the authentic version from DIYmod or the (potential)replica from Amazon. Which the Amazon one is what I got and it worked amazingly.
Screwdriver
Cotton pads/Q-tips
Isopropyl alcohol 70/91 preferably 91 since it’ll dry faster.
Soft bristle brush/ ESD brush
Scissors
Tweezers preferably ESD Tweezers
Put the PTM7950 in the fridge for an hour before starting as that’ll make it easier to work with.
After you're done with putting the PTM7950 on the gpu and you install it back into your pc. Run the gpu through some stress tests not only to check if the pad got installed properly but to let the heat cycles make it work as good as it can. Not totally necessary as by normal use of gaming or anything else that's gpu intensive will put it through the heat cycles. If you want to do it yourself however this is what i did.
10 minutes stress test with the heaven software.
10 minutes "cooling" I just turned off the stress test and let my pc idle.
Repeat 5 times.
I’m going to be uploading much more from now on. Not just car stuff but some self care content, vlogs, and maybe more pc stuff. I’m going to have much more fun with this instead of keeping it strictly informational. Thanks for watching and reading.

The thickness is not an indicator of if it is legit. Honeywell has datasheets and physical properties specs for the PTM7950. Thickness can be 0.2, 0.25, 0.3, 0.4 and 0.5mm. A lot of misinformation and confusion regarding the thickness. Not sure what the chinese stores are selling, but same as you I can confirm that ot works great.

[@GetSmart77]

I had no idea it was very confusing trying to figure out what was legit and what wasn’t. Thanks for the heads up. Even if the one I used was fake it works which is all I need haha.

At a previous job they put me on to using Eye Tees (makeup applicator sticks) for getting into difficult places while dealing with very little to no lint compared to generic Q-Tips/cotton swabs or coffee filters. Especially if I find I need to use a little pressure, like the corners of a die and PCB, or in between heatpipes, this can be helpful. The issue is you feel a little bit ripped off compared to generics, but if you're working on expensive hardware or rare goods it stings a bit less. Otherwise thanks for making a pretty clear vid that showed some of the difficulty of working with this material, but also how well it works at the end. Although, I think Ghost Goku will haunt my dreams for a bit now

[@Gubbae]

thanks for making this. my hot spots temps are about 20 c over my GPU temps on my 4080. ordered some PTM 7950. hope it works

[@GetSmart77]

No worries. 20c delta temp probably means you’re getting some pump out. Let me know how the PTM7950 works.

[@scambio_termico]

I also had hotspot problems on the core of my rtx 3080ti ... 30° delta between central temp (70°) and hotspot (100°) ... over time I tried 4 thermal pastes, but they all pumped out too quickly (mx-4, mx-6, nt-h1 and tfx). I solved it with the ptm7950 purchased on "moddiy" and now after more than a year from the application I'm only having 6° delta between the 2 values ​​(69° and 75°) ... crazy, and I think that, even liquid metal can't perform so well.

[@megaseppohovi789]

Ptm 7950 fixed my hotspot temp problem with rtx 4070. Gpu temp was ok but hotspot could go over 100c. Repasting it with normal paste awlays helped for a while but paste always squeezed out and temps were back high. Now i have been using ptm and max hotspot temp with fur mark is 81c.

[@GhostMotley]

Brilliant reduction in hotspot temperature, I believe you can buy a deshroud mount for this kit on Etsy.

Gives protips Also I forgot to take the other screws lol

[@syncmonism]

The difference in temps here is absolutely insane. What's the point of making such an expensive graphics card and then doing such a half-assed job with the thermal compounds? It would be a relatively cheap way of helping to reduce failure rates, reduce warranty processing/ repair costs by reducing warranty claims, and also reduce the speeds that the fans need to run at. Decent thermal compounds would be a fraction of the price of retail prices when bought in bulk by a company like Asrock. We're talking less than 5 dollars per graphics card. It doesn't have to even be the same quality of thermal compounds used in this video, it just needs to not be as bad as whatever they used, or maybe the issue is to do with how well the compound they used worked with their cooler design. The bottom line is that obviously something they did just wasn't working nearly as well as this after-market thermal compound. Also, someone really needs to take these companies to court over the "warranty void if removed" stickers. Not only is it illegal to deny a warranty claim because someone has performed their own maintenance and removed one of these stickers, it is illegal to provide false information which misleads people as to whether they are eligible for a warranty claim, so they are breaking the law by just putting these stickers on their products. They can argue that they're trying to discourage people who don't know what they're doing from doing their own maintenance, but if they really care about that, they need to change what the warning labels say. For example, they could provide QR codes which link to detailed tutorials on how to properly and safely disassemble the cards and/or provide maintenance on them.

[@GetSmart77]

Spitting facts rn bro. Having to experience this is completely unnecessary. In any Graphics Card range whether its budget to expensive dealing with something as simple as a thermal paste problem shouldn't happen. I'll give credit to certain AIBs tho. I've seen a lot of gpu owners who have perfectly fine temps even in the long term it seems. Fuck the warranty void sticker.

[@syncmonism]

@@GetSmart77 Agreed, it's just especially surprising on a high-end product with a massive heat sink like this one.

[@Kenj040x]

So The Hotspot problem on asrock card was this slimy Thermal Creamy substance? So i just need to repaste it? and then im happy?

[@B_rett_B]

I bought 2 7900 xtx pg's last month. Both cards had aweful hot spots. One had a hot spot of about 105, the other was pegged at 110 with memory temps getting up to 105. I repasted both. And with aggressive fan curves if i leave their out of box overclock on them of 2900-3000mhz both card will go up to about 95 still on heaven, and up to 110 when gaming on titles such as cyberpunk and enshrouded. Just got some of this in the mail today. Im planning on repasting both. AGAIN. Twice within 2 weeks. Ive thought about buying waterblocks too but am unsure if itll do much good. Maybe these cards are just junk?

[@hsnbored]

this is great, thanks

[@fellpower]

When i see that temps, im sooo fine, that my cpu, vrms and gpu is under water. no time over 40°C under full load

[@youcainthandlethetruth]

How long have you had your gpu for before seeing high temps? I have a month old 7900xtx asus tuff reaching 82c Hotspot im keeping a eye on it seeing if it goes up more. Im sure im going to have to repast it

[@ugxrorke3190]

what should the hotspot temps even be on these cards? i have the asus tuff edition and i have not seen it go 90c on hot spot yet but i also heard using a different cable can help :shrug: maybe you can test this and do another video covering this? i'm not sure how true it is tho not sure how a cable to can effect temps

[@GetSmart77]

Normal temps from what I've seen of others is 60c - 70ish on the gpu temp and for hotspot i would say 75c-85c. More important than just looking at your hotspot temp is the delta between gpu temp and the hotspot. For example: a 65c normal temp with 95 hotspot is 30c delta (95-65=30). The bigger your delta the more likely you have a thermal paste issue. Don't forget room temp can have a decent affect on the temps my room is actually pretty cold so using the temps I got could make it an unrealistic comparison to your setup. I've seen that cable problem where a bad DP cable can make the gpu crazy hot. Ancient Gameplays covered this much better than I ever could and after watching his video I changed my DP cable to a high quality DP40 cable from Cable Matters. That didn't change my temps at all but made me feel confident that it was a thermal paste issue. It wouldn't hurt to try getting a different cable. I got mine for about $17. I will probably make a brief video on idle temps and how you can help with that.

[@ugxrorke3190]

@@GetSmart77 i have on average a 10 c difference between core and hotspot temp, just added 2x PTM7950 to my amazon basket for my cpu as well as GPU becasue why not

[@GetSmart77]

Future proofing haha. You can probably just order one big piece from amazon. I imagine that would be cheaper. After doing it to my gpu and seeing my results I was thinking of doing it to my CPU. Might make that a future vid.

[@ugxrorke3190]

@@GetSmart77 yes please i'm interested in seeing the results because if its not going to make a difference then i might not even do the CPU

[@Hybrid_Phantom]

My 7600 is @ 50c and the hotspot is 64c.

Do not use 70% alcohol for delicate electronic components. Minimum 90% As anything Less risks mineralization/ residue From the water. maybe not the first time but overtime This is a surefire way too cause, corrosion and or shorts on your expensive components. If you're cleaning your computer monitor or your gaming controller, any plastic? Yeah, use 70% if you want, or just some freaking soap. But. for electronics don't half-a$$ it... 90% minimum. Other than that. I couldn't watch much. more because of your pop ups and your. channel name is get smart, which hurts my head. Keep it up and good luck.

Exactly 💯
