Pc fans - need some help

Hi. Im setting up a couple pc fans for a new veggy box. Both are 12v 0.05a. Im wondering if i can take a 9v 300ma power supply and use that for both?

Mostly curious about the ampere. I hear if i get that wrong, it could go warm and be a firehazard.

I found i had some spare fans. 4 pin. I have marked out the yellow for power. Is it just connecting that one and the ground to the powersupply to make it work?

The project have reached the drawing table (insert dramatic music)

Just order a 12v DC power supply from amazon or Ebay. The 9v wont work, but the 12v will power both. Good luck

It depends on the fans start voltage. If fan can start at 9V there is no problem with amperage: fan will draw no more then it needs. Connect your fans in parallel mode, so they will draw 0,05+0,05=0,1 A < 0,3 A that your power supply gives.

Alrigth! Thank you for the feedback!

It worked out perfectly. Doesnt run hot, and is superquiet. Cheers. Gonna start building the box.

You are welcome! I myself do run a PC fan from 5V phone charger.
