Hmm I repasted my 7970s a year ago, but I can't remember if I used my nice stuff, or my cheap stuff. I'm starting to get some higher temps that I used to, so I might take em out again, clean, and repaste em.
Thanks for the reminder!

My Sapphire 7970 has been a PAIN in the ass ever since I got it. I switched over to LTC a few weks ago, and it took me forever to get the hash rate up to 725 kh/s. Once I finally got that sorted out, my temps started to become a problem. When I first started mining ltc, my temps were around 75-80c. The temp slowly kept rising till they were in the 85-87c range! I had the side of my pc open and a box fan blowing right on the card, and it helped a little at first, but then the temps were back at the 85c range. This is in an air conditioned room.
I tried cleaning the card, maxing out fans etc, nothing helped, and it was driving me nuts. The pc kept restarting itself from high temps. I finally ordered some thermal paste and replaced what came with the factory. It was super easy, 4 screws and a twist and it was open. The factory paste was thick and had spilled all over the transistors surrounding the chip. I cleaned everything the besi I could, used a toothbrush to get the paste off the transistors, and added the new paste.
I am now running at max load, an hour later, I am at 735 kh/s and gpu-z says my core temp is at 58c! my VRM temps are at 78-80c!
I hope this helps any one else struggling with rising temps this summer.
