Frostytech tests the stock heatsink that ships with all E4xxx series Core 2 Duo processors. Is it any good?

"The stock Intel Core 2 Duo E4400 heatsink is composed of two sections - the first an outer ring of extruded aluminum with 26mm long curved bifurcated (split) cooling fins, the second an internal 33mm diameter solid cylindrical aluminum heat spreading core. The aluminum slug at the center makes direct contact with the processor integrated heat spreader, conducting the heat it absorbs out to the larger fin surface area."
