So I was looking at a lot of Dell/Alienware forums and YouTube videos, including some people trying to mine crypto and run local AI on this card. There was a common theme of using thermal pads a bit too thick. So I decided to document what I have found with my Dell 3090. It is possible this is only for my revision of the 3090, which used thermal pads instead of putty.
This PC is a build for my college student-teacher for him to run local AI.
Taking it apart is pretty straightforward since there is no bracket, so I didn't really bother taking pictures of it.

1/2: backplate

5: You can take off the frame and add thermal putty in between the frame and cooler. This will drastically decrease VRAM temps. I went from 95c down to 80c!
6: The PSU I bought for this build is delayed, so I have to use my test one.
7: Just temp testing.
