Thermal management specialist Asetek has developed a new pump technology that promises to deliver both quieter computing and optimum cooling performance. Liquid Temperature Fan Control offers users either automated fan speed adjustment for plug and play usability or hands-on tweaking, for those who like to take control of their hardware. The company has also updated and re-issued its ChillControl monitoring and control application – a one-stop-shop for checking, defining and adjusting system cooling performance parameters.

Asetek says that its new Liquid Temperature Fan Control technology automatically adjusts fan speeds at the cooling system's radiator. This should help reduce sudden bursts of fan activity during short periods of use for a much quieter overall experience, boosting cooling performance and allowing for significant CPU and GPU overclocking.

"Liquid Temperature Fan Control technology leverages the higher thermal capacity of Asetek's liquid coolers to effectively cool CPUs and GPUs across sharp spikes in load without spiking fan speed or noise," said Asetek's Steve Branton. "The technology gradually ramps fan speed to maintain temperatures during sustained loads delivering an optimized overclocking and quiet computing experience."

The technology is offered in two fan control strategies, both with integrated temperature sensors to keep a check on liquid temperatures and adjust fan speeds accordingly. The automatic system uses built-in control curve presets to oversee performance, while the interactive option allows PC tweakers or gamers wanting to get the most out of their computer systems to set their own speed curves.

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

Systems with interactive control include a USB interface to Asetek's ChillControl monitoring and control app, which gives users the tools to define their own speed curves or choose from a selection of presets. The interface also shows details of liquid temperatures, fan speed, pump speed, and sound level. Users can even use the app to change the color of the lighting in the pump cap to match a user's system lights.

"Basically, it started out with our Vapochill and Waterchill products, which were pretty complex systems," the company's Zack Fanning told Gizmag. "Now, we have managed to reduce the hardware to fit inside the pump cap, as well as making the software more user friendly."

The app is said to allow for quick swapping between three cooling modes. Maximum fan speed can be engaged for optimum overclocking performance, or for quieter operation there's a silent mode, which makes use of the liquid cooling properties of the system to keep fan spin to a minimum. There's also a custom mode where users can set their own speed curve.
