Know before you buy
A 280mm radiator requires a case with mounting points for two 140mm fans side-by-side. Before purchasing, check your case specifications to ensure it supports 280mm radiators, as some mid-tower cases are limited to 240mm models.
The cooler will function and maintain your cooling curves without the software running, as settings are saved to the pump's onboard memory. However, you will need the iCUE software installed to customize the RGB lighting effects or adjust fan profiles.
Yes, this model supports sTR4 and sTRX4 sockets, making it compatible with many AMD Threadripper CPUs. Always double-check your specific processor generation against the supported socket list provided in the manual.
The fans utilize magnetic levitation bearings, which are designed to minimize friction and noise. While they will ramp up under heavy CPU loads, they remain significantly quieter than standard sleeve-bearing fans at comparable speeds.
No, the cold plate comes with high-quality thermal compound pre-applied to the base. This ensures an even, optimal spread for heat transfer right out of the box.
The lighting is controlled exclusively through Corsair’s iCUE ecosystem. While it integrates perfectly with other Corsair RGB products, it does not natively sync with motherboard-based RGB software from other manufacturers.
