Hi I have replace the stock fan of my H100i GTX with some ML120 (the value pack Corsair CO-9050039-WW ML Series) Much better, as case doesn't go into tumbler mode anymore at full speed but not silent either. As anyone tried using Noctua NF-A12x25 PWM with the H100iGTX ? They seem very good (even come with a full frame rubber seal for watercooling heatsink), but after some digging in these forums, it seems that you cannot plug any fan into the H100i or you may toast it (ie CM JetFlo). So I thought it would be better to ask here before spending £54 and be sorry that my cooler is fried
