Radeon HD 7950 Overheating

[wcrb15]

Ok so I bought a used HIS ICEQ Radeon HD 7950 a few years back. It was running fine paired with my Phenom II X4 955, but I semi-recently upgraded to a FX-8350 and now the GPU is overheating. Like hitting temps over 90C under load with an ambient room temp of like 20-25C, and hitting idle temps of over 50C. I'm thinking of trying to pull it apart and reapplying thermal paste before just buying a RX480. Anyone have any experience pulling this card apart? It looks like the back plate might have more than just the 4 screws around the GPU. I watched the video Linus did about taking apart a GPU and that's the only reason I'm going to try it because I previously would have just replaced it. I've also blown out the card as best as I can with compressed air and that hasn't seemed to help much. Any advice?

Do this. Use Arctic MX-4 or EK Ectotherm as they are not conductive/capacitive

Will do. I'll order some of that TIM. Thanks for the help. I'll let you guys know how it goes.

Np  BTW, because you are applying thermal paste directly on the die, make sure that you have enough thermal paste to completely cover the die.

That's a good tip I hadn't considered lol.

those cards do run hot

I had seen some people saying that but it doesn't seem like it should be running hot enough to shut the PC down lol. When I put the card under full load for too long even with the fans manually on high the temperature continues to rise until the PC shuts down.

I used some Arctic Silver Ceramique that I had on my GPU and it seems to be running correctly now. Still idles around 50C but only gets to like 65C under load. Thanks for the advice guys.

you are right, my statement was comparative to intel cards which run cooler.

 

ok, ive looked on net and idles for card range from 35c-45c approx...

 

under load from 60c-85c approx....

 

so 90c is hot and will cause shut down....

 

possible causes list

 

1) bad air flow (poss fan failure,clean fans and fins, ensure max fan activation @70c)

2) bad thermal paste(paste can dry out-needs to be re-applied)

3) bad case air flow (ensure space round card has free air flow, change fan slot)

4) bad game settings eg Anti alias settings high etc.

 

fixes clean card reapply thermal paste

use gpu-z to test idle and full load... monitor idle temps first then load

 

this should do it

hope this helps

Yep it was the thermal paste. I applied some new TIM and it's working as expected now. Thanks for the help.
