no PWM / 146,9 m³/ 18,1 dB(A)

High quality fan, very low noise, and very long MTTF.

If you want a really good fan with a high quality this is the fan to choose. How much does it cost if a(cheaper) fan dies during the lifespan of the server? Or if your disks die because they overheat because of chasis fan problems?

Most server cases are provided with standard fans. You now have the option to proactive replace your case fans with these. Also if  you are replacing the fans with silent fans, these fans you need.

Please note that the motherboards we sell have a 4-pin header with PWM so please take the 4-pin model and not this 3-pin model without PWM.

Our advice, take the Supermicro Motherboard and connect PWM case fans to Peripheral zone fan headers and let PWM control the fan speed based on the PCH temperature.
