Comment: Have built a lot of amd computers and this is the first one I've ever had any heat issues with. The mobo is an msi k7n2g. athlon xp 2200 with a big copper zalmon flower heatsink and a large fan. I originally used the stock heatsink/fan with artic silver but was getting a whopping 70C idle. Painstakingly removed and reapplied compound--5 times. Tried different thermal compound, same high temps. Put a copper Zalmon flower heatsink in there, used artic silver, big fan blowing on it. Now it goes around 62C full load--that is very high for a copper flower heatsink. Two rear exhaust fans, one side fan. Spread heatsink compound thinly as recommended (I've done this before a dozen times). I'm beginning to think the mobo is reporting incorrect temps. MSI PCAlert 4 reports same high temps but I believe it just reads the BIOS. However, PCAlert 3 reports very COOL temps (around 40C idle). What the heck is going on here? Tried motherboard monitor but it can't read anything, reports 0C. Am going to upgrade the BIOS I think. Anyone know of another cpu temp monitor program that does NOT read the temps from the BIOS? I need to figure out if this BIOS is pulling my leg. Thanks all.

Reply: (edit)Well...why don't you feel the heatsink itself. If its really 62C, it will be hot!! If its just a little warm, then your 40C sounds about right. Sounds like a case of mistaken identity, but always trust your bios temp. Go look for an update, and maybe your board just has a habit of reading higher temps than others.

Reply: (edit)Your board reads the on-die thermal diode so it reports a 10c-15c higher than another board that reads a probe. http://www.amdforums.com/showthread.php?threadid=199273

Reply: (edit)Thanks both for the replies. I wondered if the new msi boards were like the Asus boards in that respect. BTW, I flashed the BIOS and lo and behold the temp plummeted. It has been running Sandra burn-in tests for a couple hours now and it is only 43C. Idling around 35C. And that is with the stock heatsink/fan. With the copper flower it was idling 29C, below ambient. How strange is that? Heatsink feels only a little warm. Thanks.
