For the 200mm case fans we have selected the high quality and very reliable Noctua's versions.
There are 2 versions the 3-pin and 4-pin. The 4-pin version is with PWM. Our motherboards we sell have 4-pin headers, so please take the 4-pin version. With PWM the speed is automaticly adjusted. If you don't want to enable PWM take the 3-pin version. The fan will then most likely always run at top speed.
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.
