    4 fans, 3 normal headers + 1 "power fan" header. How to connect?


    Hi guys.

    I received 3/4 of my new hardware yesterday. So, today, I decided to unpack my (huge) case to check out how will connect everything and also learn to "play" with it.

    So, the case has 4 fans (Lian-Li Lancool PC-K62) with 3 pins. According to my motherboard manual, there are 3 system fan headers, 1 "power fan" header and, of course, 1 CPU fan. From the 3 system fan headers, one has four pins.

    So, how am I suppose to plan on how to connect them?
    Thx for the help

    P.S The motherboard is a Gigabyte X58A-DS3R

    There are plugs on the motherboard.

    The CPU fan (and heatsink) should be right next to the CPU.
    The others (system fans 1 and 2) are also on the motherboard, but that will depends on the layout. Check the manual, or just look on the board itself.
    I don't know about the power fan...

    Again, read the motherboard manual, it should show where each fan goes.

    It is possible to connect a 3pin fan on 4pin onboard,just make sure its the right fan for the job..Won't damage your Hardware you can plug it in while the system is running!!

    The pwr_fan header can be used for a case fan

    Thanks for the info. I'll be sure to check the pin layout in the manual so the pins fits accordingly.

    Thanks for the info. If I can use it, that means I have 4 case fans headers!

    EDIT

    LOL... reading the manual sure gave me an insight and the answer to my question was in there too XD

    Lebon14,
    I would suggest you use a high quality fan controller. One power in from the PSU and all four case fans attach to it or more. Flexible fan speeds can be helpful with non premium fans for noise and heat control. The addition of temp probes which can monitor case temps is also handy. Many good makes and models available this link is just one. Good luck and I hope this addresses your connection issue.....oh it looks cool as well !

    Added value for cable routing as it keeps this away from the mobo headers.

    I disagree. You would only need a fan controller if your motherboard is unable to correctly regulate the fans.

    Temperature probes also cannot give an accurate reading of temperatures. I.e., they cannot give CPU core temps, just its outside temp.

    His motherboard should be able to run the fans just fine (and should be auto-regulated by the motherboard anyways).

    There are also fan Y connectors (splitters) available on eBay

    My take on this a little different then Lordbob75's. I think it's better to keep the additional voltage out of the mobo and I like the clean routing of the fans to controller but I do agree that the temp. probes are just a novelty as they will only give you case and surface temps. For me I watch my vital temps with software like SIW and I would disagree that having the control over my fans is a bad thing. I will agree thought that with really great quality fans as with Noctura's the need for the controller is rather mute as they run so quiet at wide open and you don't hear a difference when slowed at least in my case. Either way its personal preference !

    I don't want a fan controller because I don't need it. I'm not that hardcore... I just want to plug the fans >_<
