My new HTPC build. PSU fan mod to Noctua NF-A14 ULN (Corsair stock fan was stupid loud). Minor case case for AIO water cooling. Had some parts from old build mixed with some new stuff. Swapped out stock Fractal silent 120mm fans for Noctua NF-S12a PWM's did the same on AIO NF-F12 PWM. Machine sounded like a leaf blower in my living room until the Noctua swap. Can not hear it at all now! SSD boot drive on MoBo sata header and 3 4TB WD Red on Rocket card in RAID 5. This pulls double duty as a HTPC and storage server. i5 OC'd to 4.2GHz cooler master AIO keeps it very cool at idle 26 degrees Celsius under load stays under 50 degrees Celsius.
