XPG VENTO PRO 120 PWM Cooled by Nidec GentleTyphoon 4-Pin PWM Connector Daisy Chain Capability Dual Bearings Efficient and Silent Performance High Static Pressure 5-Year Warranty COOLED by Nidec GentleTyphoon The best overall static pressure optimized fan makes a strong comeback for the most demanding builds in a revisited capacity. 4-Pin PWM Design and Daisy Chain Capability  Pulse Width Modulation (PWM) allows motherboards to alter fan speed RPM dynamically and smoothly without annoying stepping. Flat cable design paired with its Daisy Chain capability, its easy to connect and simultaneously operate together to manage temperatures more efficiently. High Precision Dual Bearings Equipped with high-precision Japanese quality Dual Bearings, XPG VENTO PRO 120 PWM fan can withstand heavy duty loads and endure the highest thermal environment. Dual Bearings also operate with greater efficiency, granting quiet spinning and longer lifespan. High Static Pressure and High Airflow XPG VENTO PRO 120 PWM has high static pressure up to 3.15mm H2O, and its capable of producing up to 75 CFM airflow, making it an ideal air intake/exhaust gear to complement water cooling radiators, or to be installed at the front despite front panel and dust filter limiting airflow. QUIETER by Nidec DESIGN Innovative fan motor design and motor support mechanism utilize a double-vibration reduction structure and a spring instrument to greatly dampen and reduce vibration. In addition, the fan propeller is meticulously designed to reduce the disturbing frequency fan noise to a more refined \"vibration tone\" better suited to human ears. In addition with the 4 anti-vibration rubber pads, XPG VENTO PRO 120 PWM operates at mere 28dB(A) even at its maximum fan speed of 2,150 RPM (100 duty cycle). High Thermal Endurance XPG VENTO PRO 120 PWM Fan has a verified MTTF (mean time to failure) 250,000 hours at 25, or 60,000 hours at 60 ambient, which makes it ideal for heavier duty loads, e.g. more space-constrained builds with higher internal temperatures. Taking advantage of the high precision dual bearings, XPG VENTO PRO 120 PWM Fan can quietly operate and maintain stable at a large temperature range.
