liquidpaper007 means if the air is blowing in the right direction.
I got myself a FM121 last week, and man does this thing blow air, pretty impressive. I mounted the fan controller inside my case, because I like a smooth case, and not with big buttons sticking out of it :P And I dont need to change the speed everytime, so i've put it in the case. Im getting myself another one pretty soon, together with a SI-120
