Why do the MicroFins® Technology Coolers better than other coolers?
The traditional methods to make the heat sinks are Extrusion, Forging, and Die- Casting, and the maximum fins can be manufactured with a density approximately 20 to 40 fins their thickness or diameter. The material must mix with other metal to form heat sink with the thick and low-density fins that can't meet the thermal solution for the CPU. Some other method mix copper with other material to form the outer frame and brazed or weld the fins into the heat sink, which created the interface layer about 2 to 3 degree of the heat increase between the bottom heat sink and the fins, and also its very difficult to control the quality of the mass production heat sinks because some poor contract or disassociate of brazed or weld fins which is not a reliable products.
Nevertheless, Dynatron's MicroFins® Technology coolers can eliminated all the weakness problems. MicroFins advantage points are:
The Intel retail heatsink that comes with the P4-478 CPU is a massive piece and equiped with a low rpm 70mm fan. It cools efficiently and is very quiet. It is adequate for most overclock operation. Most aftermarket HSF does not perform much better. If you don't overclock, tt may be a better deal for you to get the retail CPU and keep the 3-years warranty as a bonus.
But the CPU does get up to 55-65 degrees C under full loads. If you still want to buy an aftermarket HS, here are some reviews:

The Thermoengine Arkua-8169 Copper Core Cooler is one of the high end option.
Or you can get the Thermaltake P4. As low as $8 from PriceWatch.

Nevertheless, Dynatron's MicroFins® Technology coolers can eliminated all the weakness problems. MicroFins advantage points are:
- Fin Cross Section - the cross sectional shape of the fin is skives with thin slice with 0.35 mm and 1.0mm pitch in the 60 x 60 heat sink that is better heat dissipation.
Fin Density - high density up to 60 fins for AMD K7 and Intel FC-PGA CPUs.
Fin Distribution - formed ideal distribution, the fins arrayed uniformly on the base without the interfaces, which decrease at lease 2 to 3 degree of heat source.
-applied the high quality of aluminum, and the copper to build the heat sinks for Cooler series.
Unique High Quality - cut though the whole pieces of aluminum or copper evenly to form up to 60 high thin fins, and all heat sinks are unique high quality in our production line. In conclusion, taking performance factor into account, Dynatron's CPU coolers had high-density fins 2 to 3 times than other coolers, and reliability quality products, we highly recommend high density fins of heat sink with high pressure drop cooling fan for your GHz CPU.
