computer fan?

i checked the search and found nothing, so how would i go about hooking up a computer cooling fan (zalman 120mm) to the circutry on my growbox? what wattage/voltage does it run on (theres absolutely no specs on the companies website)

they are usually 12v, 300-400 mA

Try a cell phone charger or any small plugin device you have no use for.

Here what i used works great. try to match the voltage to the charger. charger needs to put out more than the fan needs.




Good luck

Great advice besides the last part. Exceeding the fans capacity can lead to a lot of problems. Try to match it or hit just below

thanks for the cell phone charger tip, that sounds like the best way to go,
and njsurf fer sure, jersey totally kicks the shit outta everywhere else

Yes you are correct on that. You wound not want to use a charger for a power drill or large tool. I always forget that you have to consider the common sense factor. Print it and they will build it as stated without regard as to if it will work correctly. Always research research before DIY build anything to do with power you can get hurt or burn your house down.
