I have an Asus P8Z77-v mobo. All the fan headers are 4pin. My fans are all 3pin. One fan a CoolerMaster SickleFlow has an adapter to connect to psu via 4pin molex connector. Can the 3pin connectors be plugged into the 4pin headers?
"Note When connecting a 3-wire fan to a 4-pin fan header, the fan is always on; there is no fan control."
