Asetek, a supplier of liquid cooling solutions for computers, has developed a technology that adjusts the radiator fan according to the temperature of the liquid going through the pumps. This is excellent because it keeps the computer quiet during less demanding tasks.

Asetek liquid temperature fan control technology is available in two versions: automatic and manual. Both use firmware and temperature sensors built into the pump to control radiator fans. The automatic version uses values speeds stored into the firmware for fan control. The manual version interfaces with Asetek ChillControl software, giving enthusiasts the choice of using preset fan speed values or controlling fan speed with custom parameters.

The Antec KÜHLER H2O 620 liquid CPU cooler is the first product to feature this technology.
