IceGiant Shows Off AIO CLCs Powered by ProSiphon Technology—No Pumps

IceGiant at the 2025 International CES showed us their ProSiphon TITAN series CPU coolers for workstations and gaming desktops. These are closed loop liquid CPU coolers based on the ProSiphon technology IceGiant innovated. It works on the fluid siphon technology, where a thermal gradient in the loop drives coolant instead of a pump. Heat dissipates more efficiently to the coolant, and there's no crackling noise from the pump. The only downside to this are that the siphon tubes are rigid and you have to plan your build well.
