CPU Temperature Sensor

[Steve R]

Hello there.

I'm wondering if anyone knows how I can disable the CPU temperature sensor on my machine. It is causing the PC to shut down when encoding videos and that sort of thing.

I don't believe the CPU is overheating, just that the sensor is giving false readings. I've tried Everest and the readings are indeed all over the place.

There doesn't seem to be an option to disable it in the BIOS, so I'd like to know if there is a way to disable it in the O/S or physically.

I'm running XP Pro.

Thanks.

How do you know that your cpu isn't overheating? Since the PC is only shutting down during video encoding, I'd say the censor isn't the issue, for if it was then you'd get false readings at other, less cpu-exhaustive, times.

I'd suggest taking the cpu fan, cleaning both contact surfaces with alcohol and applying some decent thermal paste before reattaching said fan.

Thanks Sam, but I am indeed getting false readings at all times.

Everest shows - 8C.......75C........23C........42C.......80C.....and so on, on a second-by-second basis.

censor/sensor - Freudian slip?

Depends what videos you are encoding !!

Oops!

I'd been reading Mike Freemen's posts just before replying to this!

It does indeed look dodgy, but it could be to do with how the 'S'ensor is picking up the temps from the cpu (one part of the cpu with a good contact and themal paste would be a different temp to a bad contact on a different part of the chip maybe?).

Still, I've never had a motherboard that shuts down my pc because of the cpu temps, only warnings, which were easily disabled.

I should imagine that if it is indeed the bios that's closing down your pc, then I'd have thought you'd have got some sort of notification within windows, or an error code. Any shutting down without warning during cpu-intensive times is more often than not an overheating cpu.

I really would try and clean all the contacts between the chip and fan, re-apply paste and clear out any dust. If this all fails then it's a new motherboard for you.

Can anyone please tell me how I can disable the CPU temperature sensor on my machine?

I really don't think that you want to disable the sensor Steve, if you have Everest go to Tools and try the System Stability Test, this will show the temperatures and if your CPU is Throttling or not - best maybe to test the CPU on its own and leave it running at 100% usage for a couple of hours, to see if it passes.
As Sam says it could be your heatsink and fan have not been installed correctly and a bad contact between heatsink and your processor would more likely lead to erratic temps than a rogue sensor.

What processor, heatsink and motherboard do you have anyway??
If it is an intel core 2 duo you don't want to be going into 70 degrees at full load or it will shut down.

Hello Crofter.

I don't have a 'Tools' tab in Everest. Perhaps this is because I'm using Everest Home Edition?

[crofter]

Yes that could be the reason, you can do the same thing by downloading and installing these free programmes (will only take a couple of moments):
ORTHOS PRIME this will stress your CPU to 100% Usage, leave this running for a couple of hours
SPEEDFAN this will give you more accurate temps of your CPU and motherboard

As I say just stress the CPU not the memory or hard disc and monitor the temps via speedfan.
