A funny thing has happened to CPUs, their not as hot as they used to be. In some cases, Intel Core 2 Duo processors are pushing out as little as 65W, while some Celeron chips output just 35W of heat! It's quite a change from the long standing belief that newer processors will always output more heat. Glacialtech's Igloo 5058 Light E heatsink stands a squat 55mm tall and comes with a fixed speed 80mm fan that rotates at a quiet 2600RPM. Weighing in at a feather 263grams, the Igloo 5058 is compatible with Intel socket 775 CPUs outputting 95W heat or less.
