PWM temperature? What's that?

[pirred908]

I tried useing the search function, but nothing came up. Anyway, my question is:

What is the PWM? My motherboard shows the temperature for it in the BIOS, and it seems to be getting excessively hot. How can I figure out what this is? Thank you.

PWM is a method of controlling motor (i.e. your fans) by giving the motor a series of really quick on and off commands. This way, you can reduce the speed of your fan without lowering the voltage to the fan.

Your motherboard can measure the temperature and according adjust fan speed via PWM controller.

What is excessively hot? That means nothing without specifics. Also what's your system specs?

Not that you are wrong but PWM is much, much more then that.

In this case PWM actually refers to power delivery components on the motherboard for the CPU.

Correct. And those components typically have a very high tolerance for heat. Over 100C.

Mine are always around 65C loaded, and I'm rock solid stable.
