Today I came to my PC after hearing a clicking noise and feared a HDD failure but turns out it's just one of the 3 Phanteks 140mm fans that has bearing failure. Rather than replace just that one I have decided to throw them all i the bin and get nice new ones designed to have a long MTBF with quietness in mind. The case is an Enthoo Evolv ATX and I have 2x front intake and 1x rear exhaust configuration. A H115i sits at the top for CPU cooling with 2x Nanoxia Deep Silence series fans PWM controlled to silent running. All the case fans are running in silent smart fan profile in the BIOS anyway so hover between 590 and 720rpm. I'm after 3x quiet fans that do push decent air still if anyone can recommend something? I don't need/want RGB lighting etc, just black fans and if they have red accents then that's a bonus as it will go well with my interior decor Cheers!
