Dynamic Bearing Case Fan Hydraulic 140mm 1500RPM PWM Intelligent Temperature Control PC Cooling

Feature: 1. SILENT FAN: The for MFDB fan has eight soft silicone pads at four corners to absorb vibrance at high speeds. The maximum noise is only 35.1dBA, which is equivalent to the sound of falling leaves, so that you can resist noise interruptions while working or playing 2. EFFICIENT HYDRAULIC BEARINGS: The cooling fan use ultra durable for MFDB dynamic pressure bearings. The magnetic bearing technology with low friction coefficient has longer service life than traditional bearings, and the bearing life can reach more than 10,000 hours 3. PWM INTELLIGENT TEMPERATURE CONTROL: Can dynamically control the chassis fan speed in the range of 800‑1500rpm to reduce noise. The PWM pin can be inserted into the SYS FAN pin 4. 7 BLADE DESIGN: 7 high pressure fan blades can reach 53CFM at 1500PRM. Chassis fans focus on improving performance, bringing stable wind pressure and strong air volume 5. EASY INSTALLATION: Computer fans are compatible with all types of cases and easy to install. User friendly power supply interface design, ready to use, 125mm screw hole distance(distance between center points of two screw holes) Specification: Item Type: Dynamic Bearing Case Fan Material: ABS Dimension: Approx. 140 x 140 x 25mm 5.51 x 5.51 x 0.98in Screw Hole Spacing: Approx. 125mm 4.92in Bearing Type: For MFDB Rated Voltage: 12V Rated Current: 0.25+-0.02A Rated Speed: 800-1500RPM+-10percent Airflow: 110.5CFM Function: PWM.
