OK, I've got my computer case opened and I'm ready to try this for the THIRD time. Check my rig details (link in my signature) to see my system stats. Basically, I have an Alpha PAL6035 w/ Sunon 24cfm fan. ASUS PC Probe reports the CPU temp as 61C when doing minor tasks. I just ran 3D Mark 2001 and Quake 3 Demo, and it shot way up to about 70C.
So, hopefully the third time is the charm. I will say that the bottom of the Alpha heatsink is almost a mirrored copper finish, so I assume I need a very very tiny amount of thermal compound. I first used this cheapo grey crap that came w/ the heatsink, but I was told it's silicon based and it sucks, so a friend of mine loaned me a white colored compound he says is lead-based. Here are the details on the compound. It's by Thermalcote. Its properties are below.. I'm typing them exactly as they appear on the tube, because I don't know what these notations mean.
Color: opaque white
Temperature range: -40F to 400F
Btu * ft
Thermal Conductivity: 0.43-----------------
Hr * F^2 * F'
Dielectric Strength: 300 v/mil
Volume Resistivity: 4 x 10^14 ohm-cm
Solvent: acetone
So you can judge whether it's good or not.
As I said, the bottom of the PAL6035 heatsink is VERY smooth and shiny, and I read somewhere that if the heatsink looks like that, you should use as much compound so it looks like a translucent haze. I can tell you that last time I put this stuff on, it was definitely an opaque white coating on the CPU. Perhaps I put too much.
OK, I just tried installing the heatsink again. Someone asked previously if I installed the clip on correctly, so this time I installed it "the other way" (which IS the correct way? one side of the clip is short and has a swiveling piece on it, the other is long and looks like a squared off triangle). I still get the same results, about 60C idling.
What am I doing wrong here?!
