Can I plug two Aio coller fans to motherboard cpu_ opt and Aio_pup hedaers for better control?

I just built my rig and it has corsair h110i aio water cooler and two hd 140mm corsair fans on it. But, the corsair link software runs them on silent mode really loudly, maybe its because they are 140mm? But if not, I would love to plug them in to my mobo but I have only cpu optional and Aio_pump hedaers left, they look the same and have the same specs. Would this work and also are 140mm fans loud on 800 rpm??? maybe I am used to quiet notebook fans.

Thy in advance.

Depending on the motherboard, AIO_PUMP won't allow changing of RPM speeds because AIO pumps like to run at 100%. CPU_OPT would be fine, but your chassis fan headers should also be PWM compatible so it wouldn't make a difference. I believe 800RPM is the lowest they can go, so if they're still loud at that low of a setting then there's not much that you can do.

800RPM is near-silent for my HD120s, but I also have a case that's good at sound dampening. 140mm tends to be a little louder, so it is probably audible. If it sounds like a lawnmower then it's pretty likely that they're not being PWM controlled lol.

sorry they are 140mms and running at 1400rpm, and I cant change their speed from corsair link. and also on the box it says max 1350 rpm but link says h110i fans both about 1400.
I have no mor chassi slots left.

You can use CPU_OPT but I don't think AIO_PUMP would work with fans.

Buy a fan hub or a few Y-Splitters for all of your case fans. They're fairly cheap and would work better.
