New Asetek Pumps Enhance CPU & GPU Performance

Liquid Temperature Fan Control Delivers Optimum Cooling and Quiet Computing

Asetek Inc., the world’s leading supplier of liquid cooling technology for computers, today announced two new pump technologies that deliver optimized cooling and quieter computing.  The new pumps use Liquid Temperature Fan Control technology to automatically adjust fan speeds at the radiator. This technology boosts cooling for significant CPU and GPU overclocking and keeps the computer quiet during less demanding tasks. The Antec KÜHLER H2O 620 liquid CPU cooler is the first product to feature Liquid Temperature Fan Control technology.

Asetek’s new pump technologies give Do-It-Yourself PC hardware and gaming enthusiasts a choice between two liquid temperature fan control strategies:

  •    Automatic liquid temperature fan control provides a “Plug and Play” user experience.
  • Interactive liquid temperature fan control for those who like to tweak and monitor their hardware.

Both pump technologies use integrated temperature sensors to monitor liquid temperatures and adjust fan speeds. Preset speed control curves are built into pumps with automatic fan control. Pumps with interactive fan control include a USB interface to Asetek’s ChillControl™ monitoring and control app.

ChillControl gives enthusiasts the ability to define their own speed curves or select between preset curves. It also provides monitoring of liquid temperatures, fan speed, pump speed, and sound level.  A purely fun feature of ChillControl is the ability to change the color of the lighting in the pump cap to match your machine color or mood.

“Water has a thermal capacity 4000 times greater than air,” said Steve Branton, Director of Marketing at Asetek. “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. The technology gradually ramps fan speed to maintain temperatures during sustained loads delivering an optimized overclocking and quiet computing experience.”
