Keezer fans

[LILJONNYWV]

Does everyone use compurter fans in their keezer and what is the best way to hook it up?

 

[Bean]

I have two fans in mine. Basically, I spliced them into an old cell phone charger.

I had extra connectors from an old computer PSU so I used those with the fan. That way if in the future I need the fan for a computer, I can still just plug it back in.

I can't seem to find a power supply that works. Most don't start the fan spinning.

What voltage and amperage do you need?

 

[schmoe]

I think mine is 12V. I don't remember the amperage, but it wasn't much.

I have 110 vac fan and tied the power wires into my keezer cooling circuit. So when my keezer is cooling or running my fan is going and mixing the air up. Not sure if this link will work but this like mine.

It should say on the fan very small what kind of amperage and voltage it needs. Less volts or amps will usually make it spin, but not as fast as it could be. If you go over though, you're going to blow the fan.

This seems like a great idea. Why wouldn't you just plug a splitter into the power out from the ranco or JC controller and then plug both the freezer and the fan into that?

What voltage and amperage do you need?

Be sure that the transformer is DC. Some are AC output. The transformer amperage is not critical. Don't exceed 12V on the power supply as it could smoke the fan. Less voltage is OK, but not more. I've had good results using a 500 ma 12v DC wall wort.

This is what i use for my fans, the 1200ma allows me to add more fans as i see fit, look at the fan, somewhere on there it may discuss the voltage and amperage requirements.

I partially disagree
If you furnish the fan with 12 volts, and it runs on 12 volts you're fine - that is, if using a wall wart that provides 1 amp, and the fan draws .04 amp, it won't blow the fan, the fan will simply draw what it needs.

But if the voltage supplied is 15 volts, you're supplying more than it needs - it will spin faster, but shorten the life.

Nice idea. the fan i used came out of an equipment rack and they run on 110 so I just had to plug it in. I am currently using my dual stage controller so I just plug the fan into the second stage and match the "on" time to the keezer. when i get around to needing that controller for something else I will keep this in mind.

Sorry, just came back to correct myself... this is correct ^

It makes it really easy to piggy back fans. I have 4 or 5 dead computers laying around so I steal parts from them for other projects.

I just use an old power brick off some computer speakers. Works plenty fine. I installed an extra outlet on the back of my keezers collar for it.

This will work as well if you aren't able to wire up a computer fan.
