Which temperature to trust?

[sheemone00]

I recently purchased this motherboard MSI K8n Neo V2.0 H.

The problem is that two temperature monitoring applications are giving me two different CPU temperatures.

One application, MSI issued monitoring program, is giving me 28° - 30°.
Another application, SpeedFan, is giving me 40° - 44°.

I'm thinking of trusting the MSI issued monitoring program more, but maybe you guys can give me some insight.

Thanks in advance.

CoreTemp is generally considered a very reliable gauge of temperature. Give it a try and see how it jives with your other programs.

Edit: CoreTemp might not work on that old 754 AMD.

id go with the MSI supplied program. speedfan doesnt support my new AM2 system and it shows by saying that my core is at 3*C -_-. Stick with MSI

CoreTemp will work for your AM2 CPU.

Ok, last night I tried CoreTemp and it showed temperatures similar to SpeedFan (39° - 43° idle).

I forgot to mention in my first post that in the bios the CPU temp is shown to be around 35° - 37°.

Summary:

MSI CoreMonitor: 30°-35° @ idle
SpeedFan & CoreTemp: 40°-45° @ idle
Ambiance: ~80°F - 85°F (27°C - 29°C).

HeatSink: ThermalRight XP-90 w/ AS5
80mm intake, 92mm exhaust, 92mm blowing onto CPU.

Which temperature to trust?

Just out of curiosity, why does it matter?

Any of the temps you've listed are well inside the safe operating temp for any modern CPU.

Cause I want to OC the CPU and when I start increasing my voltages I want to have the most accurate reading.

And when I start stress testing, I want to know whether its really 70°C or if its actually at 60°C.

With that cooling setup, the CPU will hit a wall that no amount of voltage will overcome long before you see 60C. The only way you'd hit 70C is if the heatsink was not seated properly.
