IceGiant sells high-performance CPU coolers that use a sealed, pump-free “Thermosiphon” design instead of traditional heat-pipes or AIO liquid loops. The line-up is two-model: the flagship IceGiant ProSiphon Elite (≈ US $170) and the newer ProSiphon V3 (≈ US $140), placing the brand squarely in the premium air-cooler tier. Products are sold factory-direct through theigt.com and via a handful of North-American e-tail partners; no retail box stores carry inventory. The company’s entire identity is built around the claim that a gravity-fed, dual-phase thermosiphon moves more heat than vapor-chamber heat-pipes without the failure points of pumps or permeable hoses. Review outlets regularly show the ProSiphon Elite keeping Threadripper 3990X or Core i9-13900K below 70 °C at sustained loads—performance that lets IceGiant market itself as “air cooling that beats 360 mm AIOs.” Buyers are workstation builders, over-clockers, and small data-lab operators who need 24/7 thermal head-room but refuse pump noise, coolant evaporation, or maintenance downtime. The brand appeals to engineers and content creators who value reliability metrics, open upgrade paths, and a “no-nonsense industrial” aesthetic. IceGiant competes in the narrow gap between flagship twin-tower air coolers and 280/360 mm closed-loop liquid units. It differentiates by eliminating mechanical pumps, advertising zero RPM idle noise, and offering a 10-year warranty that covers both base and radiator sections—positioning the cooler as a fixed-installation asset rather than a consumable component.
