i think i found a way to run this board in my flat AND stay together with my girlfriend

i replaced the stock fans with 3 of this: http://www.blacknoise.com/de/products/it/16/Noiseblocker-NB_BlackSilentFan_92mm

the heatsink doesn't stay as cool as with this default airplane turbines, but i think it will work

i will take some pics later
