Cooler Master JetFlo 120The 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.
Ultra-Durable, Self-Lubricating POM BearingPolyoxymethylene (POM) is a highly rigid and abrasion resistant material that self-lubricates and enables an incredible 160,000 hour lifespan for JetFlo. The POM Bearing is enclosed in Cooler Master's patented Oil Recycle Bearing System (ORBS), which provides IP54 water and dust resistance.
Quiet ReliabilityCooler Master's POM Bearing technology helps reduce vibration and noise while offering consistently lower friction levels than traditional bearings.
Immensely Powerful Fan BladesUltra-thin fan blades enable minimal resistance and maximum performance - up to a staggering 95 CFM of airflow with PWM functionality. Unlike other fans that disperse air over a large area, JetFlo generates concentrated airflow in a tight radius.
