Thermocouple Probe Question

[Reyzac]

Where do I access the temp sensors on a P4? I may have forgotten to mention that.

So thanks, I think I'll refrain from trying to stick it in between. I think otherwise I'll just use the side of the heat spreader, you can still easily access it under the block.

IIRC, they're on-die, under the heat spreader and inaccessible.

[KaptCrunch]

yes on die thermoressistors is the way to go with speedfan,real temp are some apps out there

or for spot temp cheaper

[Reyzac]

Thanks for the info guys, I'll see if I can get readings from the temp sensors on die.

you can't just run a thermocouple between a chip and a heatsink, that will mess up the heatsink entirely unless you drill/etch out a channel in the heatsink.. but then you're just going to be measuring that specific area, not the entire chip.

I'd find a way to measure the exhaust temperatures. that's your best bet with something like that. stick it in between a heatsink fin somewhere not too close to the fan..

what's wrong with your onboard CPU temp sensors?

and yes, flattening the ball will likely mess up the probe.

CPU temperature sensors aren't very accurate and are totally useless when you go below 10C on the CPU. If you are an extreme bencher or using the power of the Canadian Outdoors you might want to even have a rough idea of your CPU temperature.

Below 10C is not going to happen. The sensors will be fine for my application, and I still have the thermocouple just in case.
