Hello,

I will share my story about my RX6800FE

2 days ago i wanted to change my thermal pads on the VRM, memory and GPU.

When i have open the cards i have see on the GPU a thermal pad like graphite one. After so many research its a from HITACHI and they are not selling it. SO !

I have put thermal past on the GPU and closed it

I have do one test ingame. 110° on hotspot... **bleep**?

Ok i open the cards again and i decide to change all thermal PADS on VRM and memory and remove the thermal past in the GPU for a thermal pads.

I installed on the gpu a thermal pads silicone 1mm and in all VRM and memory the same 1mm.

Second test still 110° in the hotspot...

Ok i will start to burn this cards next time.

I open the cards for the 3rd time i keep on the vrm and memory the thermal pads 1mm. BUT i remove the thermal pads on the gpu for a thermal PAST this time and i will try again.

You know what? Still 110°....

I have make a research in the internet about that i found nothing just for the RX6800XT but maybe its the same... 

Ok my question is. 

What thermal pads mm i need to use for GPU, for VRM, for MEMORY? 

Fan curves are modified.
And before this problem my temps of junction never going up than 85° ingame.

Hi, the appropriate pads for best results, is that if you are using a firmer thermal pads. It should be 2mm for Memory Chips and 1mm for VRM. Though if you plan on using a soft pliable pads, use 2.5mm for Memory Chips and 1.5mm for VRM. For the heat sink pads, 1mm should do and I would go for the GPU die until 4 years or so. But if you are replacing it too, think you should consider Thermal Grizzly Kryonaut should give outstanding result or even Noctua T-H1 or even ARCTIC MX-4.

You know my hot spot was hitting 110 and Junction was 82C. I was set all my fans all there full speed but only got 109C. I tried to figure out why? But then I realized that my power plan was at Saver Mode and knew the Prism was quietly spinning. So as soon as I put on Balanced, it started running at it potentials and so the hot spot went down to 100C. Just some information if you are running an air cooler.

ty for reply, i put 1mm TP-3 pad from artic on all VRM and memory, with a mx6 from artic too for the die. And its fine now... i dont understand...

Glad to know you fixed it. Probably hardware not seated or the pads needed some time on use to transfer heat and gain enough conductivity.
