This works maybe. Some motherboards don't boot, when there is no speed signal at the cpu fan connector.German <gentgerman@gmail.com <mailto:gentgerman@gmail.com>> schrieb am Mi., 3. Feb. 2016 um 16:01 Uhr:Hi people, Here is the thing. Building new little build. My motherboard accepts only 3-pin CPU connector, but sysfan has 4-pin. My CPU cooler has 4-pin connector (PWM). Is that a good idea to plug CPU fan connector to SYSfan connector? Thank you.
My experience has been that the 4 pin fans work just fine with a 3 pin header. The 4th pin is an extra mode to control the fan but most motherboards can also use the older 3 pin method. The connector is built to allow that to happen.
