Fan problem

  1. I am just about finished building a new micro cabinet. Cabinet is 24" wide 14" deep and 30" tall. I have 1 80mm intake fan fitted to a 90 degree 2" pvc pipe coming through bottom and 2 60mm exhaust fans connected to 2- 2" 90 degree pvc pipes running out the back corners up high. Light is a Mars hydro 300w (140w). My problem is that the 2 exhaust fans, which are the same model, are blowing different amounts of air. The one on the left seems to be blowing out twice as much air as the right one. Both are connected to same adjustable power supply at 12v. My temps are around 85, but I feel that I could get them lower if the second exhaust fan was blowing the same amount of air as the other. Anyone ever experienced this or have any explanation as to why they would be blowing different amount of air seeing as they are exactly the same?
  2. They are parallel, I believe. All red fan wires nutted together with the red power supply wire and all black wires nutted together with black power supply wire.
  3. I figured it out. I hooked each fan up individually and that fan was just slower than the other 2, but in the process I pushed on the center of the fan and it made a click almost as if the motor wasn't seated all the way. Seems to be blowing harder now, just a lil louder almost as if I pushed it too far. But it will work.
