I guess I dated myself by using AS5... didn't know that they haven't kept up with R&D. I'll need to give that TX-2 stuff a try, not conductive is quite appealing.
I reversed my case fans so that the window 120mm was bringing in cool air while the twin 60mm fans on the back were expelling hot cpu air. That seems to have helped a bit, Prime95 blend temps are stable at 55C. That's not what I want, but at least it's not 61C.
I downloaded CPUID's HM and it agrees with SpeedFan. AMD's OverDrive is misreporting my core temps, odd.
The base of this heatsink does not completely cover the cpu. I remember that it didn't cover my 3800+ and didn't think much of it when I installed it. But that 3800+ would naturally run much cooler than this beast. So, I guess I need a new cooler. I'd need to get a new case to fit the water cooler that corsair makes... no room in the back for a 120mm unit.
What do y'all suggest? I've avoided buying another heastink+fan system due to market saturation. Too many choices. A quick newegg search turned up Newegg.com - ZALMAN CNPS9700 LED 110mm 2 Ball CPU Cooler
