I've connected a fan to a DC converter and it worked for awhile. Eventually it started to smell weird and the fan stopped working. I think I'm overpowering the fan, but I don't know any other way to wire it. Can anybody help with this problem?
When a computer fan plugs into the motherboard it send out the necessary voltage stepped down through resistors. You need to find a better fan
These fans are brand new and have been used by other people doing grows. The adapter I'm using is 10V DC. I know the fans are good so is there anything else I can do?
I think I may have figured out what is wrong. The fan is rated 12V and the output on my adapter is only 10V. I'll have to find a different adapter then try it out. The adapter can power the fan for a few minutes but after that it dies.
That doesn't matter, it'll just spin at lower RPMs. Sounds like your problem may be with the transformer--is it providing enough amperage? Make sure you aren't shorting out anything too.
Go to Radio Shack and pick up a 12v adapter with 1.5a rewire to that Problem Solved here is link http://forum.grasscity.com/general-indoor-growing/370802-wiring-computer-fan-s-run-120v-c.html
