Hoping someone here can help me with my issue. Just built a new system (see specs below). Been a longtime AMD user and just switched over to the "dark side". The huge overclock potential won me over.
My issue is related to the temps I'm seeing whenever I overclock. At idle, I'm seeing temps in the 42-45 range. I'm using Intel's TAT to monitor temps. From researching around, the consensus is that this is the most accurate tool for core temps. When I full throttle the cores using TAT, the temps climb into the upper 60's, usually topping off at 70. I've also been monitoring the temps on my GPU and they seem on the high side as well. The idle temp is usually 70c and goes into the mid 80's when playing a game.
Doesnt seems like I'm pushing the CPU too hard. My friend has a similar machine and he only hits high 50's at full load. He's at 3ghz with those temps. It's very puzzling as to why his temps are so low. There are three main differences with our configs - videocard (x1950xt 256), psu (silverstone Element ST50EF) and case (antec solo).
Anyone have any clues to why I'm having these high temps? I've already lapped my stuff and redid the mounting. Could my PSU be the problem and causing my components to run hot?

It is running a bit hot, but not dangerously so. Are you running the fan at ful RPM? If not, crank it up. since you lapped the cpu and hsf, are both of them mirror smooth now? If thats the case switch to Arctic Silver Ceramique, silicon based thermal pastes work better then as5 when the cpu is lapped. Something would have to be really wrong with your psu for it to cause high temps, if that was the case your system would probably be dead already. Dont worry about the gfx card, then run really hot.
Out of curiosity if you open your case do the temps remain this high? What is the ambient temp in the room?
Those temps do seem awfully high to me for that setup, but you do have a lot of heat generating devices in the case, so I was thinking you may not have enough fresh air flowing through the case to cool all of that gear down.
5 Hard drives... are they blocking the flow into the case from the front? I am not to familiar with the P160 layout but I just looked at some pics of an empty case and it looks like with 5 drives you could effectively build a wall behind the case fans.
I had a similar temp issue due to poor case flow, when I took off the side panel the temps dropped considerably. Reorganizing my case to allow more flow resolved it.
There may be more to it as well, but case flow is the foundation of cooling so best to start there.
What are your idle temps?
(edit: just noticed you had posted idle temps)
To me 42-45c at idle is way too high assuming you have a room temp of 20-25c. You can expect a delta in the temps to be 20c from idle to full load, so if you can get your idle temps down to a reasonable level you may have solved your issue.
If you hadent lapped the IHS and HSF the AS5 might have performed a little better, but on a mirror smooth surface AS5 isnt the way to go. How much paste did you use? If you used to much or to little that could account for the high temps.
My temps at idle are even a bit higher than yours (OC @ 3.2 ghz) but my case is near the furnace vent.
I can't get CoreTemp to run AT ALL in Vista, so I've resorted to TAT. It seems a bit higher but I can't tell for sure. However, sitting idle in BIOS for awhile shows temps noticeably lower than in TAT, so I'm not sure what to make of the disparity.
I know that some programs display temps ON the core and some display ABOVE or NEAR the core, but I can't find which program is which. I would assume TAT and BIOS would be the same, but apparently not. So which is "more" correct? I don't know. I just make sure my OC temps @100% load both cores doesn't go past 60c on TAT and I figure I should be fine..........

jerrycurls, As closely as I watch the temperature threads, sometimes one gets by me, so I appologize for not catching yours sooner. Thank you for the information. You covered everything except ambient temp. It seems that everyone is only looking at half the picture.
Some users also may not know that C2D's feature 3 temperature sensors; a single on-die Tcase sensor (between the cores), and dual Tjunction sensors (one within each core). Consequently, there is much confusion regarding specifications, calibration offsets and test methods, so results can be difficult to decipher and compare...
Your CPU temps are relatively normal. Please read the following Sticky for information regarding appropriate temps:
