Cpuidle and other cooling programs

[progiciel]

Hi,

I read a discussion about the problems that using cpuidle can cause to processors, because of the constant change of temperature. However, I understand that some operating systems like WinNT issue a HLT command just like cpuidle or rain or any other cooling program. As a matter of fact, my PC runs cooler when using NT than when using W9x. What's the difference then? Shouldn't those servers running NT have dead processors every now and then because of the temperature changes? Isn't the HLT command the same, regardless of the operating system?

Thanks!

Well, yes and no.

Depends on the condition and how you've rigged processor. Constant temp changes are generally not a big issue with the processor. The danger comes in when these processors are also using an unconventional cooling units, like the Peltiers refridgeration unit. It's not the constant changes, but rather the sudden changes in temps that can cause condensation to form. Moisture, of course, can dangerous to sensitive equipment.

For PCs/Servers without these active cooling devices, the danger is generally not towards the processor, but rather the powersupply. If the power spikes are severe enough and come often enough, it can severely strain the power unit, there by causing failure, which in turn, causes other problems. This is generally not an issue with commercial servers as they're rarely in a state of complete idle. Most businesses run their batch processes at night when user activity is not as heavy. For the most part, as long as you have a decent quality powersupply, your PC or workstation should be fine as well.

Thanks for the explanation, I was just wondering if it would affect my processor if I run cpuidle. I have a Duron 600, overclocked to 800 and air cooled.
