I have a Compaq Evo D510s small form factor desktop which currently has a 1.6GHz Pentium 4 in it. I have found a place that sells the same socket processors that my computer uses and would like to upgrade it, but since it is a small form factor it has a simple heatsink and was wondering if anyone else has a SFF Evo and has done this, or if the original heatsink would be able to keep the processor cool enough, or even a heatsink that can be used in my computer.
