AMD RX 7000 series GPU Owners' Club

[Todestrieb]

Hi everyone, new on the forum.

I am the proud owner of a Powercolor Radeon RX 7900 XT and I have noticed huge delta between hotspot and GPU temp.

At 100% capacity I get around 70º GPU, 100º hotspot, sometimes even more.

I got recommendation to change thermal paste and thermal pads, any advice there? specially with the pads?

I'm kinda afraid of the process so any help would be greatly appreciated.

Thanks in advance.

PowerColor HellHound 7900XTX user here. The card was defective and sent to "repair" once, and then repasted/repadded with PTM7958 paste and GELID Extreme 1.5mm thermal pads.

After repair but before redoing the pads, I have seen VRAM at 113C without any sign of throttling.

Currently, on most games GPU temp and hotspot temp should be ~70C and ~90C respectively. But there are games that will push the hotspot to around 100C. TDUSC being one of them. No driver settings are altered, default power limit at 360W. I don't think I have done anything wrong in the process regarding to the GPU part, and most things others used to benchmark/stress test the GPU doesn't cause such a big delta, so I guess a delta of 30C is just that the workload stressed the GPU in a different way. That said, a delta of 40C is a bit...worrying.

Not that it's gonna instantly explode/degrade at that state, so use it like nothing has happened.

yeah, those are too hot of temps. my merc310 7900 xt gets to a max of 77 hotspot and like 70 core on the most demanding games at 1440p

most of the time it doesn't budge 55 core and 70 hotspot (for most games)

if its still under warranty i would RMA it. if its not under warranty, i'd change the paste out, pads change is probably ok too, but i don't know what kind you would need

Thanks for your reply, I've bought it on January but in Spain and I live in Uruguay so...
I have ordered couple of pastes and putty.
For the moment I had undervolted and limited FPS on games. Playing HD2 I was able to lower HS to 91° on the most demanding parts.
The "funny"part is that GPU core temp is 60.
VRAM also is around 80.
I hope with repaste it can go back to proper temps.
The pastes I've ordered are:
Thermalrigh TF9
Gelid GC extreme

Question: are you suggesting my temperatures are not that bad?
Honestly I would never have detected this problem if I didn't enable the option to show me secondary temperature in MSI afterburner because main temperature is always on a standard limits never be on 70°.

Also, anyone knows the thickness of the pads for the Powercolor Radeon RX 7900 XT, the only video I found on the net is not clear, it mentions 1mm or 2 mm in here: POWERCOLOR AMD Reference 7900 XT & 7900 XTX: Unbox, Tear Down, Cooler Noise, Power Limited OC & Rant - YouTube

@W1zzard How come this users posts aren't merging? Usually multiple posts, with no posts in-between will result in automatic merging of those posts.

It's bad but not throttling bad right? Then it's not that bad.
But, you have ordered pastes/pads/putty already, so do a bit more research on how to disassemble and reassemble the card.

You didn't say what exact model. If your card is the HellHound model, this video from bilibili (Chinese website warning, I don't know how accessible is this from EU, and it's already a bit annoying from here without login. I hope the link works!) can help. I have used it as a reference on how to do it on my card. There should be videos for other models. Yes it says 7900XTX, but everything should be the same except your card should have a few less VRAM chips.
Also, the video above says both 1.0mm and 1.5mm pads are needed for the HellHound, but later comments corrected that only 1.5mm pads are needed. Keep in mind if you decided to go with pads instead of putty. A sheet of 90mmX50mm is enough.

If your card is the Red Devil, use this video (again from bilibili, again a 7900XTX) as reference. 1mm for VRAM, 2mm for VRM modules.

A few post back I have shared the video of my model, mine is just powercolor with no additional names Powercolor Radeon RX9700XT. You can check in the Powercolor homepage.

Thanks!

Edit: this is it

cyberpunk - just once
metro exodus

for now.

Reference model then. Your video link should be the one you need.
