Frostytech dishes the dirt on an all copper Intel Core 2 Duo / Pentium D heatsink which looks like a million bucks, but doesn't quite stack up.... Good info to know f you're going heatsink shopping.

I really like Frosty's Top 5 Heatsink List - it tells me just which coolers are the quietest, and coolest.

"The nPowertek SF 775-2 heatsink features a body made of copper fins which have been wrapped around a central copper slug. The copper column makes contact with the actual CPU core, and the heatsinks' 136 copper fins radiate the heat out into the surrounding air. Anyway you slice it, there is a lot of copper in this puppy. Does a half kilo of guarantee amazing thermal performance? Nope, not by any stretch; it's how that copper is used, not how much is crammed in there. Of course, we'll reserve judgement until the thermal test results come in... a little later in FrostyTech's review."
