[SOLVED] cpu over temperature error

[no--name]

So I got this old PC from a family's friend, it's an Athlon 3500+ / Asus motherboard, it shows "cpu over temperature error" on start.

Cooler is properly placed and the fan is running fine (2800RPM). I will replace the thermal compound later but it doesn't seems to be the problem either.

It looks to me to a faulty sensor, as soon as I start it I got in the setup and temp is stuck on 96ºC, it never moves from there. I think CPU would have died already being that the real value.

As I said, my guess is a damaged sensor but anyways, do you guys think a BIOS upgrade could help here? anything else I could try?
I just cleaned CMOS but nothing changed.

Just buy a external temp sensor and place that right in the middle of the CPU. Install the readout unit/software and you're good to go.

The temperature sensor is supposed to be in the CPU itself, right?

Yep

Bios update couldn't hurt. Might help. Possibly the bios is corrupted or possibly the cpu is bunk.

As to the temp overheat issue, unless you have a way to disable that, it's going to cause issues. The cpu will downclock if it thinks it's overheating, lowering voltages, dropping performance and if that all fails to budge the temp, shutdown.

Those cpus are really cheap to replace, so if you do get continuing issues, I'd replace the cpu.

Yes I updated the BIOS but didn't help,
The CPU is not throttling or shutting down, the system works normally.
I just disabled the "halt on error" BIOS feature that was preventing the boot process, so far they were able to use the machine without issues.
