Canopy/Stand Exhaust Fan?

[plutoniumJoe]

I ran two 120mm computer fans from one end pulling in to the other pushing out. Worked well for me on my 75g with 2 250w and 4 t5s.

How did you power them? That is the main question because most computer fans are 3-4 pin connectors?

I used a 12volt wall wart that was on the same timer as my lights. So I only ran the fans when the halides were on in the winter. All day long in the summer.

Ive used the cheaper axial fans from JL...
I actually have one running right now that Ive probably been using on and off for 6, maybe even 7 years.

Awesome bang for buck.

Explain, do you mind linking me what you used. Are 12V adapters have the circular input plug like a laptop charger how did you get it to power a 3-4pin plug?

[plutoniumJoe]

Cut the plugs and twist the wires together.

That easy hey? is the voltage between the pump and adapter fine connected like that?

[plutoniumJoe]

Not sure what you mean. Is it a 12volt pump?
