My set up, Im running an AMD fx 8350 on a gigabyte UD3. I have3 120mm in take fans 2 exhaust, The exhausts are the back and the top the intakes are two up front and one on the side. Im using a Phantek PH tc14pe to cool the chip pointed so the front intake fans are blowing into the first 140mm fan, and I have a high rpm 80mm blowing on the back of my CPU. My room is steady between 69 and 70 F. I consistently get temps between 16 (61) and 24 (73) C (F) in normal use. When I ran Prime95 it was hovering around 36. After a few hours normal use, I popped into BIOS to check its temp and it says about 28 C. This is the same temp that CPUID HWM gives me for my Mobo Temp... This is a brand new CPU on a brand new mobo with a brand new cooler. Before I run out and try and find an IR thermometer because I think something is wrong, should I be concerned?

This what i think is happening....

In the start up CPU done a routine checkup of the hardware, this also means the processor is in working condition (but not stressed condition)...

so it's normal if it will higher than idle but bellow prime95 temperature in BIOS reading...

huh, that's weird. HWM is usually quite accurate. I second trying coretemp, though not because it's more accurate but rather because it measures from a different point. If the thermal sensor that HWM and the bios use is buggy, coretemp should bypass this since it uses the individual core sensors.

btw, idle temps showing below ambient isn't unheard of, thermal sensors are not always accurate on the low end. But if your max temp is 36C... well, that's not right.

FX chips just don't read right below 40c. Idk why or how to fix it. I just know that unfortunately that's how it is. After 40c they read just fine. It is possible your temps could just be that low with the aftermarket cooler and all the power saving options on i suppose since My 6300 @ 4.5Ghz maxes out at only about 45c on a 212+

Ya turn off all of the cool and quiet,cie,c6,apm all that junk and give it a bit of an oc. Should get over 40.
