Was your fan retail? Did it come with the heatsink?
What heatsink have you got and will it take a different fan?
The jet 4 looks like it will do the job. Have you got a socket 478 mobo?
It looks pretty impresive all made of copper. That should conduct the heat prety well!
However, it does sound a bit noisy especialy if you intend to overclock. I am not sure 3500rpm will be enough for overclocking.
Then again I am no big expert.....
If you intend to stay within the detailed specs then I do not think you can go wrong with an all copper heatsink like this one.
Good luck and keep it cool!
