Give your PC build the airflow and the looks it deserves with the UPSIREN UF-1 PRISM 4 PRO 120 mm case fan. Combining addressable RGB lighting with a high-efficiency PWM design, this fan moves serious air while staying remarkably quiet, making it a smart upgrade for gamers, builders and anyone fighting heat inside a tower case.

With nine fan blades, a fluid dynamic bearing and a wide 600-1500 RPM speed range, the UF-1 balances raw cooling performance with everyday silence. The 4-pin PWM connector lets your motherboard control fan speed automatically, so the fan ramps up under load and settles down when you are just browsing or working.

Available in black or white, in regular or reversed-blade versions, it is easy to match your chassis, radiator or GPU cooling setup and keep your cable routing clean.
