Hi all, i was wondering if anyone knew the CFM rating the little fans on the sabertooth. i'm already replacing the back little fan with a 40mm noctua fan, but i just dont know what to do the fan i want to place it, it looks alright but it's performance is prolly lacking and could be much improved with a new fan.i would be oprn to any suggestions, i wish i could put a 40mm in where the second assist fan is at but i can't. thank you.
