    Default z68 Extreme 3 Rev3 using a 2 fan cpu cooler

    On the z68 Extreme 3 Revision 3 motherboard there is a 4 pin CPU_FAN1 slot as well as a 3 pin CPU_Fan2 slot. Why is the second cpu fan spot just a 3 pin? If I am running my hsf in a push pull configuration the fans need to run the same speed. Do I need to get a splitter and run them from the CPU_FAN1 slot or plus the second 4 pin fan into the 3 pin CPU_FAN2 spot. I am just trying to educate myself here.
    Thanks

    Using a "splitter" cable is probably your best bet.
    With a 4-pin PWM cable, do NOT use a cable that has exposed male connectors, as these can cause a short circuit if the male end gets disconnected.

    Exposed male pins:

    cpufan 1 and 2 headers are linked I suppose its like a built in splitter with cpu fan 1 being the master header.

    Why is header 2 only 3 pin? It doesnt need to be 4 pin cos you will be running the cpu fans linked. I suppose if Asrock felt people wanted to run them at different speeds they could have put in a second 4 pin cpu fan header and a seperate speed adjustment.

    You will get a seperate speed readout for each fan in axtu.

    The only proviso is : To avail of the boards pwm controlled set speed and temp overide function you need a 4 pin fan on header 1, header 2 it doesnt matter if its 3 or 4 pin.Their speeds will be linked

    Connect fans: set speed at say level 5(the same slider covers both cpu fans) and temp 50 in uefi or axtu . If they are say max rpm 1800 fans both fans will only spin up to 1200 rpm approx until cpu temp exceeds 50C. Above 50C the fans will speed up towards their maximum or until the temp drops below 50C.
    Its a gradual process, ie the fans wont be speeding up and down every second hunting for the correct speed.

    You can experiment with temps and speed settings. If you leave the fans at lvl10 they will run full speed.
    I find it more convenient(less noise) to set speed and temp in uefi then only turn the fans up full in axtu if Im doing some benchmarking or testing.

    Extra info:
    I use dual fans on my cpu cooler..but if you were a single cpu cooler fan user you could connect an exhaust fan up to the cpu-2 header and have user setable temp/speed regulation for the exhaust fan.

    There is a 3 pin exhaust fan header chassis 3 ,which you can set fan speed on but it wont vary with cpu temp.

    Chassis fan 1 header is another 4 pin pwm cpu temp setable connection.
    There are 6 fan headers,5 of which you can set a fan rotation speed on and 3 of those you can set a cpu temp overide on.

    Should be enough for most, but an actual splitter should work also.
