I myself use my old EVGA motherboard with a spare Gigabyte ODIN 550watt PSU plugged in and 4x Noctua NF-B9 1600's on full whack.
Being the enthusiast, i show my love for PC hardware by using it as much as possible
To turn it off, i simply flick the PSU switch, but to turn them on, i flick the switch on, then hit the onboard power button on the mobo.
Bevelled Blade Tips Due to advanced design measures like the bevelled blade tips, the NF-B9 is surprisingly quiet despite its outstanding airflow and pressure performance. Vortex-Control Notches Psychoacoustic optimizations like the Vortex-Control Notches make the NF-B9's noise pattern more pleasant to the human ear. Smooth Commutation Drive The new SC drive system reduces torque variations and thereby ensures improved running smoothness, particularly at lower speeds. Self-stabilizing oil-pressure bearing Noctua's well proven SSO-Bearing technology guarantees supremely quiet operation and exceptional long-term stability.
