CPU fan

  slowtype 15:08 31 Mar 2005

Since installing a Jeantech 500w Psu in my Advent T9000 P4 3 GHz 512mb ram Geforce 6600 the cpu fan has been going crazy when under any kind of stress.

any help appreciated.

My guess is your new PSU isn't up to the task, despite the rating in watts.

Sorry if I'm being thick but why would the CPU fan spin more often if the power supply isn't up to the job?

slowtype, hi

I doubt it, as I said it was a guess, I can’t imagine why either. But as I can think of nothing else, I’d try switching it with another one.

Given the effect manifests itself under “any” kind of stress, it seems a good systematic starting point. In the absence of the term “any” I would suspect something was configured incorrectly, or perhaps a chipset driver was corrupted.

It might even transpire to be something basic that’s been overlooked like a dust clogged CPU cooler under the fan.

Could just be the H/Sink to proc thermal grease is not making contact correctly or its dried out, and the the proc is overheating and ramping up the cpu fan speed to try and cool it.

Does your M/Board have varible fan speed control for the CPU....?

The Change of PSU may be a red herring apart from the fact of taking the old one out and fitting a new one in, has disturbed the M/Board and broke the H/Sink seal.

Thanks to all who helped but the noise couldn't be found be 3 engineers so in the end they replaced the whole computer.

slowtype, hola

Thanks for that. Glad you’ve solved it.
