Forgive me for spamming; this is a repeat of a question that I thought might get a quicker answer if it had its own thread. (I think) I'm all ready to go except for this issue and, since I'm out of meds, I'm kinda chomping at the bit to get my medicine cabinet going. OK, so ...
I have a 25v laptop power supply hooked up to 3 12v axial fans to cool my 150w HPS in a DIY cooltube.
I strung the 3 fans together before splicing them to the adapter but, only the one closest to the power supply is spinning. There was barely, barely enough wire to hook them together so I cannibalized wire from another 12v fan to make them reach the power supply. This happens to be the link to the 2 non-operational fans. Coincidence? Or, not heavy enough wire? It's awfully skinny.
I also have a 4th fan I want to mount for circulation. Is 25v supply adequate for the 4 fans? Overkill?
How can I get all 4 fans to go? I have an old car/air pump that we used to use for the air mattresses when camping. Can I use the wire from that to hook the fans together and then to the power supply? If not, I'll have to swing by "the Shack" for the correct wire, whatever it is. Too bad I can't just go ask them, isn't it?
Thanks in advance ...
