These Temps CAN'T Be right, Can They??

DutchMike · Dec 16, 2013

Hey guys.

Got myself a new Rig with 7 CM casefans, & a DeepCool Neptwin CPU cooler.
The temps are extremely cold (even though it's 30c in my room last night, the PC was cold as ice).

However, I've recorded temps (using SpeedFan & HWmonitor, the others programs didn't pick up the CPU temp) that don't exceed 40c - using Prime95 - max usage for an hour, no errors) even though I overclocked the FX-6300 to 4.1ghz..

And last night after opening the door the idle temp became 17c...

I didn't believe this so quickly restarted my pc to check the bios, and the temps there were just a little lower. (Also did it after running Prime95, and then the temps were ALSO a little lower when getting into the BIOS)

Is my CPU really THAT cool?
Or is there something wrong with the sensor?

Mobo is: Asus m5a97 EVO r2.0
CPU: FX-6300 OC to 4.1Ghz
Casefans: 7x Sickleflow fans
Case: Carbide 300r (eveything JUST fit in it)

But man, is it loud

On most AMD processors (Athlon, some Phenoms and FX specifically) the DTS (Digital Thermal Sensor) is not at all accurate when core temps are below 40c. If or when core temps reach 40c, it'll be spot on. That's why you see abnormally low core temps when idling and possibly gaming as well (as the cores never reach 40c).

Max temps for all FX processors are;
Socket = 70c
Core = 61c

With HWiNFO64 you can check both socket and core temps which is a must when testing out a cooler in prime95.

Hey man, thanks for the reply.

Here are the results:

So WHAT IS my current CPU temp?
Do I need to combine both temps? Which would mean it's too hot?

Thanks a bunch,
Mike

But mine OCed and at full load.
Are the temps really that low or could it be there is something wrong with the monitor or something?

Would seem hard to believe, THAT cold at full load?

Thanks again,
Mike

They're probably just under 40c, which is possible. As Bouncedk said, it is not always correct under 40c.

Here are the temps with all programs that could read the them:

Hopefully these are correct like you both said, reallyy hope xD
Will try to do some more OCing, and see what happens when I surpass 40c

Or is this a bad idea?

Much thanks,
Mike

I did have a error at Prime95 it said
"FATAL ERROR: Rounding was 0.5, expected less then 0.4"
And that means??

Hey man, thanks for the quick response

Hmmm so try giving more voltage, in the BIOS right?
Just by little bits & THEN try the Prime95 test again?
It's weird.. last night I didn't have that error after an hour of testing

Thanks once more,
Mike

I was wondering the exact same thing. I'm running a 8320 @ 4.2GHz with a H100i and CorsairLink is reporting temps of around 14 C at idle and around 32 C full load. I though those were real temps and was proud of my H100i for cooling that well... But after reading this I guess I need to download that program you said.

Well, 32c at 4.2ghz is entirely possible with an h100i
