Dimmention 4700 Overheating
I recently replace Pentium 4 2.8 Ghz cpu with a Intel Pentium 4 640. I properly applied thermal paste and took precautions.
I also replaced the 160W power supply with a 350W power supply.
I upgraded the RAM to 3 GB.
I found that the heat sink is remaining hot even after shutting down my pc.
The original cpu was a 32bit Prescott cpu. The new cpu is 64 bit.

The model of CPU you chose uses too much power for a Desktop case.
Neither the voltage regulators nor the Heatsink are the proper model. 84W Prescott cpu's cannot be dropped into northwood models without consequences. 1.475V-1.55V is too high for a 1.2v Prescott.
This model is too old and too slow to be usable for anything.

The original cpu was also a Prescott cpu. It was Pentium 4 520.
