Hi,
It's a difficult one regarding the H50, Corsair recomments to use the fans on the H50 as intake, but you will be blowing hot air and without a dust filter dust over your motherboard.
I used to use the H50 in P/P and followed their advice because I had a dust filter on it and 3 exhaust fans right above it.
What i've read from other users the difference in using the fans on the H50 as exhaust or intake will only be a couple of degrees.
Anyway I don't think you have bad temps with H50 and a 940 under load.
