Did you replace the processor or is it the one that came on your model? I found an old post that lists compatible processors and info about the heat sink--

The S SPEC and STEPPING for DUAL CPU must match EXACTLY.

The Following processors are supported.  Harpertown LGA771.

There are 2 heatsinks for the Precision T7400.

FN654 - Heatsink for 150W CPUs
FD841 - Heatsink for CPUs below 150W

MaryG, thank you very much for your time!

The I bougth the T7400 just like is, I didn't do anything. I'm just trying to make it work better. I decide to buy a Xeon 5450.

Again, thank you very much!
