Plug CPU fan into non-CPU fan header?

Question for you all,

I have a Rampage III Formula motherboard, and just bought a corsair H100i for my case. The way the motherboard is laid out, there's a fan header right next to the CPU socket which would be much easier for me to plug the H100i's power block fan connector into, rather than the CPU_fan header all the way at the top of the motherboard.

I have two fan headers at the top of the MOBO (CHA_fan and CPU_fan), right under the H100i's two fans, so I think it'd make sense to plug them in there. (not going to use CorsairLink, cuts down on extra cables) Which means an exhaust fan would be plugged into CPU_fan.

The H100i's CPU fan plug is only 3 pin anyway, not PWM, so can I plug this into the header mentioned above? (Right next to CPU, and marked CHA_fan (chassis fan)

This would mean that the two 4-pin radiator fans are plugged into CPU_fan, and OPT_fan 1.

This leads to two questions:
-Is it ok to have a 4-pin PWM exhaust fan plugged into the CPU fan header? And thus, the CPU fan plug (3-pin) plugging into a chassis fan header?

Thanks,

Alright, makes perfect sense to me. Thanks!
