With the goal of enhancing the computing environment, all Zalman Tech products are noise-free. This product is a noise-free 400W ATX (version 2.03) / ATX12V power supply supporting Intel Pentium 4 and AMD CPUs. By implementing heat-sensor circuitry that controls the cooling fan's speed (rpm) in relation to the temperature within the power supply, noise has been greatly reduced.
