Hey guys.

I bought a coolermaster jetflo 120 fan and it came with 2 silent mode adapters. The stock connection is a 4 pin chassis fan connection. The two silent mode adapters are 4 pin to 3 pin, bu where does the 3 pin plug into? Does it go into the 4 pin chassis fan connection just with 1 pin removed (There's four slots, just 1 pin missing)? Or does it go into my 3 pin PWR fan connector?

There wasn't really a manual that came with it.

Also, for those who have owned a CM jetflo 120, did it make an audible whirring noise at low RPM and a buzzing at >1400 for you as well? Because mine has been doing that. I bought the fan because it was supposed to be quieter than my stock case fan, but that whirring and buzzing makes it not so.
