Well I have to agree, Mike, that Tom's Hardware's test procedure left me a little cold. In fact I don't know what his procedure really was! I don't think I'll use that link again, but I showed it just for convenience, since most tests do show that the FOP32 is an effective HSF, is reasonably quiet, fits most motherboards, and is not too expensive.
Mike:
Which three coolers do you consider the best for the P3/Athlon flip-chips?
