So I ended up buying 3 thermal pastes lol... in case one worked better than the other (and since they are cheap).
I grabbed Tuniq TX4, Arctic Silver 5, and Prolimatech PRO-PK1
The reviews seemed to lean in favor of Tuniq, so I went straight to that. Carefully cleaned off the CPU and the heatsink w/ coffee filter dipped in 70% alcohol. Think I got everything up well.
I fired up everything after letting it dry for a few mins. I can definitely see the improvement w/ new thermal paste! This thing looks like it runs much cooler on average. I got up to 4.6GHz stable. Cut it back to 4.5GHz for satefy reasons. I'll post up my temps later, my internet connection wasn't working on that computer for some reason.
It's not the 4.8GHz overclock I had previously gotten... so i'm still slightly bummed (very slightly).... so i'm wondering if I may have not applied the thermal paste as perfectly as the stock paste was applied. The stock paste came with a glob on the heatsink and it spread by smushing it. 4.8GHz overclock was no problem... even considering the fact that I had first put the heatsink on the 3820 and THEN on the 3930K, so it had already been smeared by the first time it touched the 3930K and still rendered a 4.8GHz clock speed. When I applied the paste this time... i tried to follow the less is more strategy and not glob it all over the place... but when i spread it, it didn't spread very evenly. I got a coating... but some parts were showing a little bit. Good or bad?
Do you guys think I should clean it up and try one more time by letting the heatsink spread it? Also... should I break open the Arctic SIlver or the Prolimatech bottles I got?
Or am I seriously just splitting hairs here and should just be happy w/ 4.5GHz? lol
also note:: at first, i had the heatsink on too tight again.... and 4.5GHz was crashing. I loosened up the screws and it's now stable. not sure if that plays a factor in if i applied the paste well or not, but figured i'd mention that.
