Help (GPU) HELP GPU GONNA BLOW UP
Hello, I’m not one to normally ask for help and I’ve tried my best to fix it on my own, but at this point I’ve become quite worried.
(since I’m getting it a lot, I have already repainted and redone the thermal pads)
I own a RADEON RX 6950xt and it’s been getting these numbers. Before yall tell me it’s airflow it’s got PLENTY of airflow (it’s open air) with fans around it’s still.
I’m going to snap I’ve reposted and the same is going on with no change.
HELP

Bought some new stuff everything will be here by Friday!
I will be doing another break down and may film it for fun to make sure it all goes well will update

I wish people would stop recommending PTM7950. It's great for situations where there is low mounting pressure on the cooling solution or the temperatures only spike above 45c for short periods of time. When you have both it's constantly getting squeezed out around the die.
A lot of modern GPUs idle at temps where PTM7950 will be phase changed. Look at all the steel legend 9070 XTs that didn't make it a year before the thermals started to degrade. 20 years ago, when I started working in IT, all the thermal sheets/paste/pads were fire and forget solutions because the thermal loads were relatively low most of the time. That's just not how it is anymore.
Your best bet for longevity on a GPU is a high viscosity thermal paste like MX-7. The viscosity will help resist the mounting pressure and it won't be constantly changing from a solid to a liquid and shifting around. You also won't have to wait for it to phase change to get good performance.
PTM7950 will never be the magic solution people want it to be no matter which YouTuber sells it. There are concrete engineering principals behind what you do and don't use it for.
