Chipset / PWM IC temp question

Hey all,

Should the chipset temp rise almost as quickly as the cpu temp when running@load in Orthos, or will that be the pwm ic temp :confused:

I'm using SpeedFan to monitor them, but I'm not sure I have them the right way round. I'm asking as my current X2 4200 clock ( [email protected] ) failed after 20min in Orthos and the temp I have named ' chipset ' was at 61c when this happened. The ' pwm ' temp was around 45c, core 1 42, core2 54.

Checked the temps with SmartGuardian, even though my board's an Asus A8N-SLI SE and it shows the same results which makes me even more confused, as going by heatsink tests on http://www.madshrimps.be/ the pwm temp is normally higher than the cpu core :confused:

The PWMIC is what provides the voltage to the CPU. The higher your VCore the higher their temp will go. I believe they can take up to 100C but anything below 60-70C is better.

I doubt the PWM is responsible for your instability though. Looks like you need more voltage, a better cooler or both

Thanks for the reply. I know I need a new cooler, as that's mainly why I was asking

So the 61c is likely the pwm temp and not the chipset temp ? If it is then good, as that saves me spending £12 for a Thermalright HR-05-SLI.

As for vcore, the 1.425 is whats set in the bios. Cpu-Z, SpeedFan, CentralBrain Identifier and Everest show this as 1.46 / 1.47 vcore which I would have thought would be enough, unless they are wrong of course , as it'll do 2.64ghz with 1.4125vcore set in bios, with 1.42 shown in Windows apps.
