To estatic to wait, I decided to go ahead and take it back to 240 megahertz.
Here is what I got:
Full load produces 70 degrees in TAT, 68 in Coretemp.
Speedfan reads at about 53 degrees.
Idle Tcase is 33 degrees, Idle Tjunction is 50 degrees.
This is not much better than what I got when I first started this. At least I am not hitting 80 degrees or anything though.
Any thoughts? Maybe sanding the heatsink and processor surface (the metal side that is, not the die!) or "lapping" as its called with some hi grit sandpaper would help?
It is worth noting that when i started this, I had used a screwdriver to remove the thermal compound that came with the processor, then my shirt. It did scratch the heatsink and processor a little.
Also, from the Core 2 Duo Temp guide:
"Tcase (Motherboard Utilities) = 30c Idle, 50c Load (SpeedFan: CPU or Temp X)
Tjunction (TAT) Hottest Core = 45c Idle, 65c Load (SpeedFan: Core 0 / Core 1)"
So Speedfan DOES read cores under load? If Speedfan were right and Core 0 and Core 1 are the internal temps, then I am running cooler than I thought!
Update: I took the processor to 266 just to see what happened. This was my original intent all along, to use stock cooling and get the chip up to 266.
The computer failed to do anything after that. I got a screen that said (no monitor input) and then nothing. I had to restart the computer three times to get it back to 1.8 gigahertz and to work.
Whats wrong guys? I am at my ends here. The reason I bought this processor is because I wanted a 2.4 chip but could not afford a E6600. What should I do?
