I almost never write about CPU heatsinks/coolers but the new SILENTFLUX passive pro cooler from Noise Limit Inc. certainly seems intriguing enough to write about here. SILENTFLOW is a non-mechanical, self contained system that utilizes “bubble pump technology” to deliver passive cooling to the CPU. Translation? Aw heck, I’ll leave that to the Noise Limit Press Release here:

“Noise Limit has moved beyond legacy cooling techniques, such as heat sinks and pipes, to create the next generation CPU cooling technology called SILENTFLUX. The patent-pending bubble pump design is based on a non-mechanical system that uses the heat, created from the CPU, to create hot liquid and gas bubbles which move through a hermetically sealed closed loop tubing and condenser/radiator to cool the system. The bubbles continue to circulate, condense and return creating the bubble pump. This efficient and lightweight all aluminum design reduces the need for the typical high power, high noise airflow thus creating a cooling system that is high performance, flexible, cost-effective with very low audible noise.”

Get it? Basically heat from the CPU helps to create hot liquid and gas bubbles within the tubing. The bubbles circulate through the system – removing heat from the CPU and then condenses back to start the cycle over again.

Now the best part of it? There’s no sound output because there’s no need for a fan. The next best part? The SILENTFLUX is compatible with Intel Core i7 Sockets LGA 1366, LGA 775 and LGA 1156 . Sweetness.

The heatsink measures 145.4 mm x 138mm and weighs 282 grams. No word on pricing or if this heatsink will be available to the DIY market. However, Wortmann AG, a system integrator in Germany, will be the first to use the SILENTFLUX in their TERRA line of workstations.
