diy cooling fans for lights

How did you hook them up ...can you draw a simple diagram with voltage details.

Thanks.

 

Thanks for the link and idea, maybe I'll check my old cellphone charges.

 

I got this at frys electronics...(computer store) It is 110...plugs straight in the wall.
I intend to build a canopy soon but for now I have it blasting over the deck when the MH lights come on...works suburb.

DC fans are a LOT cheaper and i have a bunch of them(from building computers)
Just need to know how to hook them up to an AC adaptor without burning the house down.
When you hook up electrical wires...or advise other people about it, you have to give them details about voltages and why it works + extra safety measures.
You cannot use just any fan on or around the aquarium. Some manufacturers tell you never to use them in certain high moisture applications.
Its not something that should be experimented with.
Could be very dangerous and even fatal.

 

I have been using 12 volt fans for many cooling situations for many years, on computers, in AV Cabinets and in custom light cabinets, they are the safest to use because of the low voltage. I would not recommend using any 110 volt fans around a tank unless you have a qualified electrician install them.

As far as burning down the house, if you hook up a fan wrong it will either #1 turn back wards or #2 not turn at all depending on the brand and thats about all.

The most your going to get from 12 volt fan is a little zap! it sure isn't going to kill you, well that is unless you have a pace maker, LOL. Thats why I use them and not the AC fans which use 110 Volts. Most manufactured lights have AC fans in them, mostly because they are cheap and safe to use.

As far as using them in a wet area you have to make sure the fan is blowing in and not out, by doing this there is no problem with moisture. I have had the same 2 - 12v fans on one of my tanks for 18 months now with out a single problem.

 

thats funny...didnt think about the pacemaker or electrical devices inside the body

would suck to get killed by an aquarium ;D

senior citizens beware

 

an old cell phone charger will work fine

 

This had me rolling on the floor. I think it should be reworded to "dont do this if you are a moron. if you are unsure, you are one"


Good tips on working with electricity though.
