Product Description.
The Cooler Master JetFlo 120 is a high performance, long-lasting cooling fan for computer cases, CPU coolers, and radiators. Longevity is a key feature in JetFlo as it utilizes Cooler Master's latest Polyoxymethylene (POM) Bearing technology. The blades found on each JetFlo fan are ultra-thin but extremely strong, enabling minimal resistance and maximum performance. JetFlo is powerful while remaining whisper-quiet thanks to rubber mounting corners that contain threaded steel inserts, absorbing most vibrations and noises.
