Testing Thermal Throttling with Northwood and Prescott

The system with a Prescott CPU shuts down at a higher temperature than that with a Northwood. The latter's peak was, in our case, 98°C, while Prescott never shut down at temperatures below 101°C, sometimes even working on at 105°C.

Both started throttling around 75*C.

Fancy a cup of tea? 🙂

Thats actually quite scary to be honest.... although its probably never going to get anywhere near that high during normal operations, the fact that it goes that high before shutting off is a little disconcerting in my view.

Dang! That's high for a Northwood. Average load temp for the Prescott, though, I hear.😀

Might seem high for peopel that build their own, BUT most OEMs woudl rather not have to put a fan on top of the heatsink. They like ot use a single case/power supply fan and have it pull air across the heatsink.
So this MIGHT hurt desktop Dells, HP's., gateways, etc... performance when doing large or heavy loaded works.

i've only been up to around 70c with my prescott
although i think it did throttle on my a few times in 3dmark
