Bij AnandTech is een handige roundup online gekieperd van een aantal Athlon Heatsinks, waaronder o.a. de Global WIN VOS32-plus, Alpha P7125 en de Montac ArcticCircle. Als conclusie blijkt voor hardcore overclockers de Global WIN VOS32-plus (met een extra 8cm fan en plastic buis waarmee de hete airflow direkt vanuit de heatsink weggezogen kan worden) het beste resultaat te geven. Mocht je geen plaats hebben voor deze grote constructie dan kan eventueel nog heil gezocht worden in de gewone VOS32 versie of de Alpha P7125.
If you're a hardcore overclocker, and you've got a case that is compatible with the Global WIN VOS32-plus, then go for it. The fan duct system exhausts the hot air from the CPU directly out of the case definately makes sense; you'll get state-of-the art performance at a very reasonable price. But be prepared to having a noisy PC.If your case is not compatible with the VOS32-plus, and you want performance without compromise, then the two heatsinks to consider are the VOS32 and the Alpha P7125 with YS Tech fans. They provide very similar cooling performance; which one you pick is a matter of personal preference.
The VOS32 has better versatility (it's also compatible with SECC2 CPUs, the fans can be mounted on the side to avoid blocking a DIMM slot) and much lower price (around $30). However, it needs a small modification to fit the Asus K7M rev 1.04, so either buy a premodified VOS32, or use a side cutter to shorten some of the fins.
The Alpha's advantage is its embedded copper plate, which further improves performance if you mount the Alpha directly on the CPU core, without the thermal plate. Keep in mind that this requires modifying the heatsink, which will take time and skill. The disadvantage of the P7125 is the high price (around $50), high weight, and the fact that it blocks a DIMM slot on some motherboards.
Both VOS32 and P7125/YS Tech are also very noisy.
