NOTE:

1.Pls be sure that this Cooler can fit to your CPU model, if can't sure, pls contact us.
2.This   Cooler is prefer to Server and Industrial Personal Computer, big   noise,  we don't recommand to use it on personal computer.
3.The fan is 4pin  with PWM and can condition the speed according to the CPU   temperature  automatically.The default fan speed model is different in   per  motherboard. (mute,standard,full-speed mode) , if you want mute   mode,  pls revise the fan speed model in BIOS, don't think that it has   only one  speed mode.
4.When you mounting radiator, pls don't turn   the singal  screw tightly at once, should fix the four sets screw on it then turn  them tight one by one slowly. (make sure the CPU  can contact  the  radiator totally and keep it balance don't make it crushed)
