I recently put together a new machine and have a few different fans inside the case, as well as a Corsair AIO. I don't really have a lot of experience with changing fan curves, but I'd like to set these a bit lower as they run at a higher speed most of the time even during idle. At the moment, I have a Corsair 4000D case with one Noctua NF-P12 (1700RPM max) fan mounted to the rear in exhaust, and two Noctua NF-P14s (1500RPM max) mounted to the top of the case exhausting as well. I have a Corsair H150i 360mm AIO mounted to the front with three 120mm fans on it in a push configuration. Corsair's ICUE software is currently controlling the AIO and fans on the radiator, but what I'd like to do is be able to set manual fan curves in the BIOS for the three Noctua fans. Right now, they're all three connected to a fan header that has a Y-splitter on it, so I can't control each individually. I'm not really familiar with fan controllers or how I need to set it up and get it configured in the BIOS once one is installed. I was wondering if anyone could offer some insight on what the best setup would be and possibly any recommendations on controllers that might fit my need.
