My System Specs

Default Mix 3 pin Fan with 4 pin PWM fan and header

So I'm trying a push/pull setup with my Hyper 212+, but for now, I'm using two different fans.
An Arctic Cooling AF12025PWM fan and a Noctua NF-P12.
The AC fan is PWM based and has a 4 pin splitter built into the cable, so I've connected the Noctua directly to this splitter and then the AC PWM fan is connected to the motherboard's header. The fans definitely don't have any issues with drawing too much power from the header (combined 2.64W vs 12W on the header).

Now what I am wondering is can I set the motherboard to control the fan speeds based on the temperature, or will it cause issues (something go boom?) because one fan is PWM and the other isn't?

Full speed is a little too loud for my tastes considering it's idling, when I'm gaming, I'm not going to hear it since the game's sounds will easily drown out the fans.
