FrostyTech has posted an Evercool NW11F Pentium 4 Heatsink review
The Evercool NW11F-CLB825CA/LD2 is a socket 478 Pentium 4 heatsink based on a fairly standard design principle. Its clear plastic fan glows a nice bright blue thanks to three carefully placed LEDs, and noise levels are generally moderate. The extruded aluminum finned heatsink section is augmented with a 25mm diameter copper core insert that rests directly on the Pentium 4's integrated heat spreader. The copper core helps to improve thermal transfer throughout the aluminum portion of the heatsink.Evercool NW11F Pentium 4 Heatsink Review
