Help needed with cabinet grow

My cabinet is approx: Height-52", Length-21", Width-18".

My problem is that I having difficulties in finding a silent way of extractor air so that their is fresh air circulating.

Ive considered small squirel cage blowers & 5 x PC fans (12v) but because of the voltage Ill have to use too many batterys.

Any advice or links to any products that may help?!

Anyone..............

you could try hooking up the 5 PC fans to a computer power suply (PSU).

also there are 220v (normal voltage) small fans

Isn't 110v normal voltage? mabey I'm wrong.

i am from europe i found that somewhere for example -Featuring smooth, ball bearing design for extra quiet operation, our 4.5", 105 cfm 110V fan can't be beat. One guard, hardware and 6' cord included with each unit.
