4600 satellite pro CPU fan

[davidflatman]

i have a 4600 satellite pro and during normal operation and with out any warning the computer freezes the mouse does not move numlock will not turn off/on, then again with out any warning the computer will be working fine again.
i have noticed that the CPU fan does not seem to be working at all and never switches on (it used to ) so i am thinking that this may be that the processor is over heating or something Long those lines. is there a program that can test the CPU fan or what can i do to fix this problem

You might need to change the fan. Try another plug to see if it still works. If it doesn't, it's useless.

I don't think you need to test the fan, if it's not spinning then it's not working.
Try what lhuser said, and if you can't get the fan working then either get a new fan, or if u can't easily change the fan then get a new hsf.
