Noctua unveiled its pumpless thermosiphon CPU cooler project at Computex last year. Now, the company is back at the Taipei-based tradeshow, showcasing updates to the cooler prototype.
The science hasn't changed. The device is still using two-phase cooling that causes the liquid to boil and vaporize at the CPU heat spreader, go up to the radiator, and then condense back into cool liquid to start the process again.
This creates a cooling system with no moving parts or pump noise, except for the spinning fans.
