Windows 10: connecting multiple sized fans to one port?

  1.    09 Mar 2018 #1

    connecting multiple sized fans to one port?


    So i am changing my pc build a bit (again) but this will be a final change (i hope). I am aiming for msi z370i itx motherboard with corsair 240 air case. I have been looking at the noctua fans for more silent with good performance in airflow. I am using a cooler master 240mm radiator cooler for my 8600k.

    I will replace the stock fans from the cooler with noctua nf-f12 pwm fans as i did some research in best fans to use with radiator. I am going to use a pull configuration with this fan and already have a splitter for the 2 fans to connect in one port. Radiator will be between fans and case (the sandwich).

    What i want to do is get 2x 80mm noctua nf-a8 ULN premium fans for the case and another 120mm (same as the nf-f12). 3 of these fans will push air out from inside the case. The 3 case fans will share connection on another fan port on the motherboard.

    Any suggestions? Should i get the 80mm pwm instead of the uln just to share connection with the 1 pwm fan (case, not from radiator)?

    After this is settled, i will install the phanteks rgb fan grills on the 3x 120mm fans and have them connection to corsair rgb port from the mobo. I know, pricey because i want the most quiet fan with rgb rather than having rgb ready fan that may sound noisey for what i am rebuilding.

    Hi TheRandomBrain

    I think I would go all PWN assuming msi MB headers support. Didn't spend a lot of time looking for MSI board specs.

    I say this as it appears the uln has two speed settings and there could be times when you will want to go even lower. Imagine your MB will have fan curves you can set depending on load rather than setting A or setting B on ULN's

    One members opinion. Lets see what others think.

    Hi,
    You're well come to add the 2 80mm back fans if you really want too
    But I'd leave it open with none

    Make the top and front as intake and all air will be auto pushed out the back no fans needed

    PMW really doesn't matter 3 pin would just use voltage offsets and will still show a rpm in hwmonitor...

    Ok. All pwm fans no matter size? I'm going to connect 2 small and 1 120mm to one connection .

    Ok. I will try it out. I just don't want dust coming in to the back of the case. Thanks

    Hi,
    It would be impossible for dust to come in from the back because of the positive air pressure from the front and top
