High CPU temp since flashing BIOS

agw_01 · 1 May 2008 at 14:43

Hi guys,

When I first built my new machine, I was getting a CPU temp of ~30ºc in the BIOS of an Asus P5K-Pro.

Installed Windows and flashed using the Asus utility.

Rebooted the system and went into the BIOS for something and noticed the CPU temp being reported as over 50ºc.

The Asus PCProbe tool reports the same, SpeedFan reports another temp and CoreTemp reports yet another temp.

I'm using water and the radiator and all pipework is cool to the touch so tbh, I don't believe any of them.

Does anyone else suffer from this?

New BIOS often recalibrate the temp sensor on the motherboard. Coretemp is the most reliable programme to use.

Cheers roadie.

I've just done a bit of searching and it does seem to be a common problem with the E8 CPUs.

Just read this thread and downloaded RealTemp.

It's giving me a much more realistic (and quite impressive) temperature of 35ºc :cool:

That's OC'd to 3.2GHz and with the rad fan set to the lowest speed.

A screenshot to highlight the differences between different applications...

You'll almost always get different readings from those three as they're calibrated differently.

Ahhh I see. So is RealTemp the most accurate program to use?

It's also the lowest which would make me the happiest

It's susposed to be the most accurate, tho I haven't used it.

Core Temp is the most commonly used, so it's good for comparing temps from other peoples set-ups.
