Temperature strangeness, please help

post #1 of 15
Thread Starter 
I've been very disappointed with my stock temperatures on my E4500 (lapped too)
but here's a funny thing, and please help me make some sense out of it
here are my idle temps according to various programs



My Motherboard program, it reports the same temperature as in the bios, and I really hate this temperature



Core temp gives me much better results



real temp gives me great results as well



CPUid gives me the same CPU temperature as my motherboard, yet my cores are significantly cooler than my "CPU"

I have an Arctic Freezer 7 Pro (lapped) with Zero Therm paste applied well (trust me I reseated 100 times)
I think my case has fair airflow considering my video card idles 32-36C passively.

Who do I trust, why the big difference in CPU temp to Core Temp?

EDIT
Running orthos Load Temperatures (stock)

Mobo ASUS: CPU 59C

CPUid: CPU 59C Core Temp 42C on both cores

Core Temp: 42C both cores

Real Temp: 42C both cores

Use Core Temp for monitoring temps, not Real Temp.

I would trust Core Temp, CPUID, and Everest.

I need more feedback people
Is there a reason I would trust these programs more than my Motherboard program and BIOS?

My BIOS read like 60C but CPUID reads 30C but the heatsink is not hot at all and a TempGun reads like 28C for the Heatsink so my BIOS are WAY OFF! Don't trust BIOS!

I'm still uneasy
can someone explain why CPUid would be reporting the same temperature for CPU as the BIOS

yet the core temperature is 15C cooler?

EDIT: but 28 for the heatsink can still mean that your cpu temp can be 60C right...? Unless you measured it right at the bottom?

Take an Average of all the Temps and it will give you a close reading!

And yes the TempGun was aimed at the Base of my Zalman 9500!

Please look back at first post, I updated load temperatures
What should I go by?
post #9 of 15
Go with the core temps. Try this LINK

It explains a lot of the technical ins/outs. Youre not alone with this problem.
post #10 of 15
cpu temp (diode between cores) read in bios, cpuid, speedfan, etc is dependent on bios calibration, you can try updating your bios, looks like Asus did a poor job of calibration, unless a more recent bios does better.

core temps, read by Coretemp, Realtemp, Cpuid, are from DTS reading diodes on die and are not dependent on bios calibration so not prone to poor bios calibration/support. They are calibrated by intel at the factory.

Your load core temps are going to be the most accurate. If you want accurate cpu temps, try update bios, if that fails send an email to asus to calibrate it better, or you can calibrate it yourself with speedfan.
