PC Stats has posted a GlacialTech Igloo 4300 Heatsink review

This is a two part socket 478 heatsink which tries very hard to reinvent the retention mechanism wheel from scratch. The Glacialtech Igloo 4300 succeeds for the most part. Instead of using two clips, or fragile plastic components, the heatsink uses a one-piece articulated steel mechanism to latch on to any standard socket 478 heatsink retention mechanism (HSRM). I seem to recall Glacialtech originally promoted this mechanism as the only one you could engage with "just one hand." That is true, with just one hand we were able to install this sucker on the heatsink retention mechanism (but are you really going to buy a heatsink because of this? I think not). In any case, it's the cooling performance we are interested in, and not the clip. As with other Glacialtech heatsinks, the Igloo 4300 uses fairly thin fins of varying height to dissipate the heat from a toasty Pentium 4 processor.
