Who do I believe? Asus or Sisoft...

Asus Probe 2.23.01 reports my CPU @ 62C
Sisoft Sandra tells me the CPU is @ 54C

Who is correct?

 

get a third opinion..

Everest reports the same temps as Sandra. Surely it will be reading from the same point though - I thought the Asus utility would have been accurate due to it being suppled with the board

 

Ok then,
how about a 4th opinion

Okies -
Sandra - mobo 39C CPU 54C
Everest - mobo 39C CPU 54C
MBM5 - mobo 39C CPU 54C
ASUS - mobo 39C CPU 63C

 

I'd say the asus is wrong.. what does it say in POST when you boot up?

 

Been looking around - what's the difference between CPU socket and CPU diode? It seems that they often give a 10C difference... if that's the case - which one is everyone using when describing their CPU temp?

 

CPU diode is on chip I believe and the socket one sits in the socket. I don't recall if it makes contact with the CPU or not but it's really measuring more air heat.

 

With no load:-

Bios reports 51C
ASUS says 53C
MBM5 says 46C

 

I'd go by the BIOS ..

 

The asus probe would be more accurate because it uses the same method as bios does. It's a program written by asus to tap into their bios to give the temperature rating. It most likely uses the on die temp diode. The other programs use a diode that sits UNDER the processor so it's going to measure at least a 10* difference in temp as the one that is in the core itself. Also that on die diode isn't that accurate either. I would give that a 3-5* increase as well at the least. Unless you have a probe that sits directly next to or on the die you will not get an accurate reading.

 

Asus probe has been known to be off by average of 10 degrees.
I also know this too be true with one of my asus mobo's.
Even on asus web site, also this has been mentioned and noted in asus's forum.
