Question 40mm Cooling Fan Help

Hey guys, i bought this 40mm cooling fan for my new labby build, and the input voltage is 12v. I am powering my laser driver with a 12v power supply, so the voltage is right. The supply is rated at 3 amps.

So my question is, would i be OK just plugging the fan into the source, or do i need some other circuit to step down the current to .10 amps?

Thanks

Default Re: 40mm Cooling Fan Help

You can directly hook it up to the power supply provided that the current draw of the fan plus the laser does not exceed 3 amps.

Yeah, fans dont need extra current limiting circuits. as long as the voltage is right it will be fine.
