ActiveCool AC4G Socket A Powered solid-state cooling system

Features
This unique active cooler is a must for anyone pushing their PC to the max. The clever design incorporates an active cooling device which can actually chill your CPU by electrically passing the heat from the CPU to the heatsink. This design can keep your CPU really cool even in the most demanding situation.

The AC4G active cooler is also much quieter than a traditional design cooler. This is because the fan doesn't need to spin as fast to dissipate the same heat. The controller circuit included with the cooler will control the speed of the cooler fan and your case fan to ensure the optimum cooling and reduce overall system noise.

Typical cooling performance:

Using AMD Athlon 2700+ CPU
Maximum CPU Thermal Power: 68.3 W
CPU temperature running SiSoft Sandra CPU Benchmark: 45°C
CPU temperature during Burn In: 50°C
Typical CPU temperature* 36°C

Using AMD Athlon 3000+ CPU
Maximum CPU Thermal Power: 74.3 W
CPU temperature running SiSoft Sandra CPU Benchmark: 56°C
CPU temperature during Burn In: 61°C
Typical CPU temperature* 55°C

* Typical indicates how the CPU performs under typical stress of Windows applications (Office package and other more intense applications). All tests were performed at room temperature of 25°C. Indicated software was run for 20 minutes to create thermal load. Temperature for all Intel P4 processors was measured with Intel Active Monitor software. A ThermalTake XaserII case with front and rear 80x80x25 case fans was used in all tests. Test results may vary depending on case design and air flow.
