Possible Duplicates:
Can I remove and put back the heatsink of my processor without reapplying thermal paste
Is it insane to replace a CPU without replacing the heatsink?
Can I re-use my heatsink/fan that is currently on the motherboard with this new Intel e5300 CPU ? I know both CPUs are socket 775 based CPUs. I have a 2.4 GZ single core Intel chip currently. Also would I be able salvage the thermal paste or should I just buy new paste?
