| Hi Mr J,
The fan you have is fine and 100% ok to use with the processor you're running. I think that model will support XPs up to 3400mhz.
First thing I would try is to ensure that the CPU fan/cooler is seated correctly onto the processor and the retention clasps are securely fastened.
Did you power the CPU fan from the correct header on the Mobo, usually marked CPU FAN.
Did you remove all thermal paste from the top of the CPU before appying the new fan?
I would not advise you to power up the PC with a fan not present. You'll probably fry the processor in a matter of seconds.
Good luck...
