Upgrade your gaming rig or workstation with the Arctic Liquid Freezer III Pro 280mm AIO Liquid CPU Cooler and feel the difference instantly. This high‑performance cooler delivers extreme temperatures while staying whisper‑quiet, giving you the confidence to push your CPU to its limits without overheating.
Two 140 mm P14 Pro PWM fans move up to 72 CFM each, providing rapid heat dissipation across the 280 mm radiator. With a fan speed range of 200–1800 RPM and a noise level as low as 0.3 dB, you get powerful cooling without distracting noise, keeping your workspace comfortable.
The pre‑filled, maintenance‑free coolant and PWM‑controlled pump simplify installation and ongoing use. Compatible with Intel LGA1200/115x/1700 and AMD AM4/AM5 sockets, the cooler fits most modern CPUs, and the included mounting brackets and thermal paste make setup quick and hassle‑free.
