Scythe NCU-2000 Pentium4 Heatsink

Frosty Tech spends some time chillin' with the Sythe NCU-2000.  This is a Pentium 4/Socket 754/939 HSF that is made to get the job done quietly.  This monster is 143mm (5.6") tall, and likely won't fit in smaller cases.  If you're in the market for some silent cooling, you'll want to check out this review.

"For the Scythe NCU-2000 to work properly inside the PC, the fins of the heatsink have to be oriented vertically. If the fins are oriented horizontally, convection cooling won't be nearly as effective because as the hot air rises, it will not be passing through the heatsink fins. How the NCU-2000 actually stays cool without a fan is what will discuss next."
