ProSiphon Technology
Superior Performance
Extreme Reliability

Designed for the higher heat loads of today’s most advanced chips, IceGiant’s technology deploys a more efficient strategy to battle heat with the use of phase change science.

There are no internal moving parts in the Elite that could break down.

By relying on good ‘ole gravity to operate rather than a mechanical pump, a prominent failure point of coolers is removed completely.


Cool air flows through the condenser and liquifies the vapor


Gravity drives the liquid back to the evaporator, and the cycle repeats



Heat from the CPU boils liquid inside the evaporator- vapor flows up to the condenser

Furthermore, the ProSiphon Elite does not use water as its cooling fluid.

The most devastating cooler failure that can occur is a water leak, which will destroy your electronics. Instead, the ProSiphon Elite contains a dielectric fluid- electronics could bathe in the fluid and work perfectly fine.

Best yet, our technology will show day-1 performance on day 3,650.

Our 10-year warranty sets the gold standard for CPU coolers.

(this warranty also covers the 4 low-noise fans that come with each Elite!)
