    Default Gigabyte UD5H Build...System Fan Questions

    First Post so let me know if you need more info on my questions... :)

    My first build by myself with the following companents...

    Z77 - UD5h Board
    i5 3570k chip
    16GB Ram
    I have a 3/4 Cougar Vortex PWM fans added in.

    Temps look good:
    CPU at idle: ~32
    PCH: ~54
    System: ~34

    I just connected the 4th "SYS Fan" to the board and that one comes on/stays at ~1700 RPM while the other 3 are 900 to 1050RPM.

    Couple questions:

    1) Does it matter if I use any of the SYS FANS for intake/exhaust or location in the case? The reason I ask is the 4th one is the side panel intake and its the only intake I have on the board. The other front intake is direct to PSU.

    2) Why does that one fan rocket up the RPM's while the others stay lower. I tried "Silent" and it drops each one somewhat, but the 4th is still much higher (and louder ;)).

    I have reviewed speeds in the BIOS and EasySetup 6 (prefer the BIOS view). Its not really a concern because of the temps but just more of an understanding why one fan seems to been going hard, while others are not. And also should have have done the fans in a sequence on the board instead of just plugging in wherever.

    Any thoughts? Again if you need more info I will post later...thanks!!

    1) No
    2) As you found out, the Sys Fan 4 is wide open all the time.

    Thanks!!

    Is this normal that "4" is wide open? If not is there something I am not doing correctly?
