CPU fan is stayong at 75-80% Max speed! Help!

[mikepg]

I have run into a sudden problem with my MSI K8N Neo 4 Platnium board with an Athlon 64 3200 CPU. It seem that the Thermaltake CPU fan (tempsensitive, and has sepreate speed control) is now running at 75% of top speed. The fan slowly reached this point over tha last 4-5 days. It started to intermittantly jump from slow to a faster speed. It would gradually increase final speed, jumping back and forth randomly.

I do not know why it is doing this, but it was a $50 CPU fan and it shouldn't be bad after 1 year. I blew any and all dust out of the case as I though that the heat sink fins were clogged, but it still is running very fast and loud! Any ideas as to why it is doing this are greatly appreciated!

Hello,

What are your system temperatures?

I do not know, how do i find this? It is not hot, I would say ~85-90 degrees F.

Is there a utility I can use to find the temp? I know that it can bee seen in the BIOS, Does the MSI CORE software do this?

Also, the CPU fan has a speed knob that is turned to the slowest speed and it is running very fast.

Hello,

SpeedFan http://www.almico.com/speedfan.php is a good program you can use to check your system temperatures.

Alternatively, you can check in your BIOS after running your ps for a while.
