GDSTIME 40mm PWM Fan 4-Pin 12V 40x40x28mm Dual Ball Bearing High Speed Brushless DC Cooling Fans

Product Description
This is 40mm x 40mm x 28mm 12 volt high speed PWM fan designed to cool various electronics and ventilate small DIY projects. such as Industrial Control Motherboard, 1U Server, Case, Computer, CPU, Heatsinks and Radiators; or as a Replacement Fan in nNetwork and Storage Equipment.
The fan's housing is constructed of PBT Plastic+30%GF UL94V-0. Reverse wind bar pressurization outer frame design to achieve maximum static pressure in all applications, this reduces the blade's noise and vibration, creating a perfect balance between power and sound by creating a compression effect and blocking any pressure from escaping. Precise copper tube structure makes performance more stable.
The 4028 brushless dc cooling fan uses a PWM 4Pin interface, with temperature control, speed regulation, and speed measurement functions. In other words, the greater the heat generated by the hardware, the faster the rotation speed, which is automatically adjusted, so the user does not need to adjust it manually.
This dc axial fan contains long life dual ball bearings, the fans can be run continuously for 50,000 hours and be mounted flat or upright.
