Ally air cooling, idle temp 10c higher then ambient

[Sohryu Asuka Langley]

sound right? 43C max load.

C/W = Delta / CPU Watts
Delta = CPU temp - Ambient Temp

find out how efficent your heatsink is...

43C is fine for a celeron.

I dont know how many watts im putting out. I could never get radiate to work anyway :(

Thats quite hot actually, my celeron 600@927mhz with 2v (runs with 1.75v only put it there to increase the wattage) with a FOP 32 was only about 35oC with a room temp of 25oC and with a glaciator it's 29-30oC with the same room temp.

What is your room temp, what case cooling do you have and what thermal paste are you using?

[JaY_III]

31 watts
if your room temp is 25C your c/w is .58
the temps wont fry your CPU... but now that i have done the math.... its the same system in your sig right? you sure you have the heatsink on correctly? Paste?

[Phil]

you don't work out the c/w from room temp, you use the ambient temp, which is measured near the heatsinks fan, except when you have it sucking where you need to use your imagination.
How are you measuring the cpu temp by the way? the on die diode or an in socket thermister?

I guess I need better grease [all i have is radio shack stuff]. My lapped to mirror finish FOP38 [32-1, actually, but just swapped the Delta from the ThermoEngine I got] comes in 1C hotter. ambient is about 19-21C. This ThermoEngine has a nice big scratch where the die sits [in USD, I got it for about $15], I'll be lapping when i wire in 1.9v on the celly.
Temps taken from MBM5 through in die diode im guessing because there is no in socket thermo on a CUSL2-C.

whoops i have always used room temps..... but then again my case is open and i have had a fan blowing air toward the heatsink/fan
