View Full Version : New computer - CPU overheating

21-01-2009, 06:49 PM
Hi, put a computer together yesterday and windows was installed with the mobo and video drivers.

Today upon start up prior to getting into windows it says CPU over temperature warning, press F1 to resume. Much of the time it cannot even get into bios without a warning.

In the bios:
CPU temperature 100 degrees celcius.
Mobo is 23 degrees celcius.

2008 RPM is the CPU fan. Sometimes 2800.
Power fan is around 680 RPM.

I have changed the settings to turbo speed for both and it has only drop the CPU temperature to 98/99 degrees celcius.

HSF: Intel OEM. No overclocking.

CPU: Intel Q8200.
Mobo: ASUS P5Q.
2 sticks of DDR 800.
DVDRW was taken out, cables pushed aside - made no difference.

Case: Antec Atlas 550, 550W PSU. Has rear case fan but no front case fan.

Thermal paste - Intel pre applied.

Did you connect the fan to the header on the mobo?

You probably did or it wont boot..

Check that the fan / heatsink is on properly

Hi Nomad,

I had a similar issue when I built my new pc a few months back. Intel E8400 and Asus motherboard P5KPL-CM. Had the cpu temperature warning come up at 100 degree Celsius. I fixed it up doing a BIOS update. Install windows and Asus has a BIOS update utility tool on the CD for the motherboard, install that utility and use it to update your BIOS to a new version. Its pretty simple and straight forward. Hope this helps.

DONT risk updating it in windows, it can freeze, then say byebye to the BIOS

If it supports updating in the BIOS, update it that way

Since your mobo supports EZ-Flash 2 (which is similar to mine the P5Q SE/R)

Go into the BIOS and update the BIOS that way (tools / EZ-Flash 2)

Put the update on a floppy / USB flash drive (unzip it first)

Thanks, CPU fan reseated and bios updated.

Appears to be working :)

It will. It complains but yes it does boot without it.
