Fan connectors: 4-pin motherboard interfaceSupports speed additional features support PWM speed control functionApply chassis cooling, CPU heatsink, transm the power supply fan, liquid cooling aided, switching power supply cooling, high-reliability server applications. Intelligent temperature control the fan is PWM fan, on the premise of motherboard supports PWM function, the fan is very quiet and general speed control at 1500 rpm, and almost no sound. Buyer please determine whether your motherboard supports PWM function, general location of motherboard CPU fan outlet is 4-pin PWM is supported, some low-end motherboards may be false t, those boards do not support the PWM, some motherboard PWM function need to go into the BIOS of the motherboard is on, otherwise the fan will run at full speed. The fan runs at full speed when approaching 5000 rpm, noise is not small, mute users, please be sure to let the fan used in PWM control.
