Been asked many times, but another on temp readings...

I've read a few posts about what program is the best to relate your CPU core temps to you, and I have looked at many of them, but I'm not sure what to believe.

My BIOS says 35-39c at idle, Everest says 60c at idle for the CPU temp, but the individual cores are at 43-47c, with coretemp right there in the 43-49c range at idle for the individual cores.

That being said my new Thermalright Ultima 90 barely gets warm to the touch, if even warm at all. I was concerned over this fact and did remove the sink, reapply TIM and reseat. I'm getting the same readings and the heatpipes on the sink barely get warm during load, and stay pretty cool at idle.

When I use Everest to load the CPU's the individual core temps increase to about 58-66c.

Does this all look normal, or would you be concerned with the temps in these readings? And why is the BIOS reading temps about 10c lower than the others (or 25c lower than everests CPU temp).

All this is very interesting, but I just want to know that everything is ok...

I would go with the coretemp readings, which have proven to be rather accurate across a broad range of systems (aka, anything that supports coretemp, the key is this program reading directly off the cpu, thus the motherboards temp diode doesn't matter). I would be concerned with those load temps...the idle temps seem fine. You are running a fan on the Ultima, correct? And what is your case cooling like? I'm guessing you are running a decent amount of fans. Is it possible your heatsink isn't flat, and thus not making good contact? It might need a lap job, which seems to be common of Thermalrigh products these days (they are the best when they make good contact!)

If you're not overclocking (can't be 100% sure from those screens) then those temps are to high. Uninstall the heatsink and the CPU, clean them and hold them against an light source and check for gaps. If you see gaps, you'll need to lap.
I'm pretty sure CPU and/or heatsink is not flat, my C2S on a Scythe Infinity dropped 11° after lapping, another 2° after lapping the CPU

The Ultima 90 is lapped (from the place I bought it from), the CPU is not. And yes, there is a 12cm fan on the Ultima.
