I have ordered a 212 EVO for a new build. I am new to PWM. If I order a Blade master PWM fan for the push/pull would it be correct to use a PWM splitter to connect this second fan to the motherboard?
If you mean plug two fans into one motherboard PWM socket, you have to make sure your motherboard can handle it. In the motherboard's manual you should find a maximum amperage and wattage for your CPU fan connector.
