S-V-K, I saw you posted the amp draw of your exhaust fan (.60)amps, This is about half of what you will need to cool 3 X 55 PL-L. You need an exhaust fan that is at least 1.20 amps, your choice, 2 X .60 exhaust fans (quieter) or 1 X 1.20 or higher exhaust fan (louder). Your intakes 2 X .27 = .54 amps, barely less than your .60 exhaust. You need to double the exhaust to intake ratio to get the cooling going as well as lots of passive vents.
Oh yes,thank you very much.gonna place an order today.this 60amp fan is 45db loud,two of them will kick me out of house hehe i mean girlfriend will kick me out.by the way,do u have any tips for silencing pc case fans ?? naaah only joke
