Its irrelevant to the post but ok.My i7 Haswell hackintosh is build in fractal define mini,antec 620 watercooler (5 years no maintenance)all three fans replaced with noctua(watercooler and two from case),asus gtx 760 my system is cheap and dead silent. On full load is compared with my iMac(mechanical drive replaced with ssd's) in idle.
----------
I have replace it with a pwm noctua fan for cpu watercooler and its dead silent idle run at 300rpm and full load handbrake 3 hours never exceed 900rpm with cpu temp at 55C.
I reckon after you've heard a nMP working in real life at full load, sitting on your desk right next to your keyboard and mouse and not under the desk like a normal case is you will think again. It has just one slow and large spinning fan as the only moveable component in the entire design. You have three fans plus I presume a 4th in the PSU. Sticking your hackintosh case on the desk right next to the can would be the only way to truly compare it and I reckon on full load in the same place there I know what would win the quiet competition!
