My build is a Be Quiet! Dark Base Pro Rev 2 that comes with a PWM board on it.
I have the 3 case fans tied to that PWM and that is plugged in to Cha_1 on my Asus x299 Deluxe II board.
In bios I believe CHA_1 is set to PWM. Other options are VA and Auto. Default was Auto. I tried setting back to that it makes it so the fans run faster by default (idle) and its hard to say if they get faster on load. If so its very slight.
When I max-cpu i.e. through CPU-Z or rendering in a program such as 3dsmax the fans remain at the same speed.
A few more details that might help

- The Be Quiet! case has a slider on the front. Left is supposed to be PWM controlled from mobo which is what i have set. And it stays "slow" it seems. If i slide it to the right (manual mode) the fans speed up immediately (at idle) and then at load seem to be the same speed (no change).
- I do not have the case side on right now. the side is open. So may be its not seeing a reason to speed up? or are the fans suppsoed to speed up no matter what during load?
- The h100i fans speed up and the read out on the CPU temp hits about 55 maximum. So the machine is running fine and not rebooting or anything like that. Idle is in the high 30's
