Case Fan trouble - Asrock z87 Extreme 4 + Fractal Design r4

hi guys,

im unable to control the 2 fans (3pin) that came with the case, Neither via software (Fan-Tastic) nor in the UEFI settings. Both fans just run at full speed. Can somebody tell me what im doing wrong?

  1. Use the Define R4's built in controller.
    Connect the controllers molex power cable to the PSU, and you can run three fans at hi-med-low from the switch inside the front panel.

    But have a good read over of the motherboard's manual. Usually you can set up a custom fan profile that might work.
  2. Check Section 4.6 of your manual on p. 97 - that's where you can adjust fan settings. Your mobo has 3 chassis fan ports - one 4-pin at the bottom edge, and two 3-pin in the middle of the board. Your case came with 3-pin fans.

    You should be aware that a 3-pin fan plugged into a normal 4-pin fan port will always run at full speed. SOME mobos allow you to alter the way that 4-pin port operates to make it behave like a 3-pin fan port, but I don't know whether yours does or not. So check the BIOS settings in Section 4.6 to see if you have that option for the CHA_FAN_1 port.

    Alternatively, you could simply connect both of your fans to the CHA_FAN_2 and _3 ports, then configure each under Section 4.6.

    The manual does not make it clear what options you have for adjustment. Usually you can disable a port (some of these may be by default), set it to automatic control, set it to a fixed speed, or set it to a version of automatic control in which you custom specify what speed it will run for certain temperature values. For the case fan ports, the "temperature" it uses is sensed by a probe built into the mobo itself.
    (For the CPU cooling system, the temp used is from a sensor built into the CPU chip.)
  3. hey guys, i connected the case controller like 2x4b suggested, it works fine. Thanks again, both of you.
