Fans (I have 5 on the case) were making a lot of noise, so I manually cleaned all of them, including the Variable Speed Fan Technology for Boxed Intel® Pentium® 4 Processors. They were really dirty, and noise decreased indeed. Since then noise disapeared but after a while I noticed that the CPU fan NEVER increased its speed again. A month later suddenly suffered weird restarts and stalls, and sometimes processor was at its 100% and the processor fan was running at the same speed. I installed Intel desktop utilities to realize it was over the temperature. My guess is that during the cleaning of the fan, and for what I read on I might have damaged the thermister.
I also read this ftp://download.intel.com/design/Pentium4/datashts/303128.pdf, but can't be sure if I damaged it or not.
My question is: How can I test the fan to make sure that is the problem? Also, is there a way to know if there is permanent damage to the CPU?
For example, Is there an utility to test fan speeds? (increasing it just for test purposes I mean).
Thanks a lot.
