Basically,
Swapped out the intake fans Corsair SP120's ~2300rpms and added two 140mm exhaust fans 1900rpm
temps are ~ 46-51c in a 20c room. Left to run overnight.

What are your chip temps? I have two bgears PWM 120mm pushing 110CFM and a pair of 140mm bgears PWM pushing another 110CFM and it still gets hot in ambient above 75F to a point where it shuts off.
