Evercool NW11F Pentium 4 Heatsink
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.
