A Cool Bunch: How To Put A Lid On The Die Temperature Of Your Athlon

A Round-up Of 55 Coolers For AMD Processors

Specific power dissipation of different AMD cores.

AMD has ventured down the correct path with its latest progeny, the Athlon XP with a Thoroughbred "B" core. The surface area of the die was expanded 5% to 84 mm2, which put its power loss several steps below that of its predecessor (as measured by clock increase). But if you compare the CPU die to a 100 watt light bulb, its specific thermal power is still fiery: while a heat lamp generates a wimpy 0.95 watts/m² (5% efficiency, surface area around 100 cm²), the latest Athlon XP2600+ churns out some 81 watts/cm². So the moral of the story is that many a little makes a lot - in this case, a lot of heat that desperately needs to be dissipated. Unless, of course, you enjoy seeing your processor disintegrate in a flash of smoke.
