I got a HAF 922 with all fans installed any way i just settled it under this desk. Any way my top fan and the CPU fan are blowing air out the side fan under fan and front fan blow air in. All 3 of the intake fans are completly unobstructed the top fan however has about 30 Santimeters between it and the desk. So i am wondering would this cause much of a heating problem it is the out take fan.
