  • question?

    What would happen if you hooked a 12 volt fan (120x120 high amp sucking) to your battery instead of the PSU? Good Idea or Bad Idea?

    I finally find a theard that answered my question.

    hmm...i dont know

    But one time, we took a 80mm fan out of computer and stuck it out the window of my car going 80mph...it was spinning so fast it hurt our ears. I still wonder how fast that fan was going.

      D batteries...

      I run 4 of my fans off of 8 D batteries = 12 V. I didnt want them running all the time and wanted to take my comp out easily (fans arent in or on comp), so using comp power was out of question. Rat Shack sells those battery packs for $1.99. Takes 4 D batteries and spits out 6v. Hook 2 of those together and you have 12v. Works well so far...

        Well I'm looking at lessing the load on my PSU. I'll just get a relay and a 3 amp fuse.

          I have my system fan connected directly to the 12V - the cpu fan not because it takes not much current -

          12VFAN on 12V should work ? or not`?

          i have my sytem hoocked up as the following
          Battery=> big big cable => PowerSplitter => Relais =>FAN&Inverter . So with a little switch i turn on and off my interver and system fan .

              I think even if you have around 13-14 V while driving this would not dammage the fan. If you feel not good by connecting the fan directly take a cheap one so that it doesn't matter if it brakes.
              Ah yes forgot - Have some equipment at home which runs 24h/day and that needs a fan - This fan is connected to a 13,2V PSU - Until today - no problems

                Running a fan at a slightly higher voltage (14vdc) shouldn't cause any problems, as people have said. If its a cheap fan, it could shorten its lifespan, but when you consider how simple of a mechanism and how cheap a fan is, whats to loose?

                  speaking of fans i found a stupid trick the other day while messing with one of those clear fans with the l.e.d's in it if you put it unplugged i front of another fan or something else that will spin the blades fast enough it generates enough power to power the l.e.d's like i said stupid trick but hey
                  WINNER!!!!
