3 case fans, one case fan header on motherboard - How should I hook it up?

Hello all,

I'm finalizing my HTPC build, but ran into a bit of a problem with the case fans.
(one thing to note: the motherboard I'll be using is actually the Gigabyte GA-F2-A75M-HD2, but can't find it on pcpartpicker for some reason, so I picked the closest one)

However, the one problem I'm currently facing is the case fans. The case has 3 fans, but the motherboard only has 1 case fan header. What would be the best options to solve this?

Also, I know the PSU is a bit overkill, but I wanted to go with a modular one to decrease cable clutter, since I will only be using one 3.5" HDD and one 2.5" SSD (possibly adding another 3.5" in the future). If you have any recommendations for a cheaper PSU that won't cause too much cable clutter, that would be greatly appreciated as well.

Thanks.

Well there are obviously fan header splitters,which would be ok for maybe 2 fans, but that would still leave one, since you can only put so many fans on a single header before you run out of juices.

With a specific 3 pin to 4 pin fan cable You can connect your fans directory to a 12V 4 pin connector from the PSU, If it's ok that the fans are running at full speed. Otherwise it might be ok to look for a fan controller where to plug in all your case fans, allowing you to adjust them accordingly.

Of course if you intend to use a DVD / Bluray drive it might not be as easy to come by considering your case only comes with one 5.25" slot however there are other alternatives, or possibly you could just place the controller inside as you probably won't be adjusting them much once you have set them to a proper speed. But if you don't use an optical drive, then there are several nice controllers in the $20-40 range to choose from.

Thanks for the answer, rvilkman.

I'm not planning on using an optical drive of any sort, as I honestly can't remember the last time I used the one on my workstation/gaming PC, other than OS installation, which I intend to use a flash drive for.

I am kind of hesitant about installing a fan controller, since all the ones I'm familiar with are quite flashy, and won't really fit well with the overall look of the case, which is supposed to fit in nicely with everything else in the TV cabinet. Can you recommend any specific fan controller that doesn't have all these crazy led's and graphics and whatnot?

Again, thanks for your time.

Don't really have a recommendation, they all have their specific issues. So i'd say pretty much check out what is available and how it would look on your machine. Most of them should be fine for you. And of course you could just hook up your fans normally to the 4 pins and see if you actually need to reduce the noise.

I just found out that the case actually comes with a three 3-pin to molex adapter (didn't notice it in the manual before, and I've never seen this kind of adapter), so I guess I'll just hook two of the fans using this adapter directly to the PSU, and the remaining fan to the motherboard. If they get too noisy, I'll probably go and get the Scythe KM06-BK Kaze Master fan controller (still available in my country), which fits nicely into the overall look of the case.

Thanks for your help!

a Scythe Kaze Q would be also a option.
