Take Care Not To Burn Your Fingers!
One of the most notorious issues with Intel's Prescott Pentium 4 is its tremendous heat dissipation. Dealing properly with the heat produced by this CPU requires care on the part of the user in selecting the appropriate cooler. To help make that a little easier for you, THG's Munich Lab has tested 5 Pentium 4 coolers for socket LGA775.
One thing is immediately obvious when you consider the coolers: they all look somewhat similar. All the manufacturers have obviously been inspired by Intel's reference design. The basic shape of each of the coolers is the same, with only the EKL cooler differing slightly: its aluminum heatsink is oval instead of round.
Why do you suppose that is that the case? The reason is that Intel's thermal design guide specifies that airflow from the cooler also must cool the surrounding motherboard components, especially the voltage regulator. It is not easy to implement this type of cooling design, so manufacturers have generally stuck to Intel's reference design.

Good to see: split fins to increase surface area.

great forum Its good that you all focus on low end coolers.next time add a little info on how thermal paste works in conjunction .I painted my whole heat sink with the stuff.Reply
pls help me...Reply
the 4 heat sink stand are broken.Is my pc is safe or i hv to buy new one.
plss help me
awhile back I bought a few cheap after market P4 coolers wasn't worth spit . nothing is better than that copper coreReply
