  • 12v Fans - Regulated or Not?

    Basically I want to mount 2 12v (0.14a) fans behind my screen to provide cooling, do these need a regulated 12v or can I just tap into anywhere?

    I personally would probably just leave them, but I guess they would react badly to spikes.....

    Sorry for unhelpfully comment :-P If people leave their monitors unregulated though, I'd think fans would be okay

      Thats what im thinking, there isnt exactly alot in them to go wrong. I just dont want to run another load of cables to the boot lol

        There is no need to run regulated power for the fans.
        More voltage (14+V???), it will spin faster, create more noise, more air and die faster too.
        Less voltage, well, just the opposite of that high voltage.

          You don't think a 30v spike would kill a 12v fan?

            Should a proper car electrical system even have 30V spikes? I think with a 30v spike, you would have worries other than a damaged fan.

              I would not have any concerns about using car voltage to power a fan.

              However, If your PS does not have the overhead for to power the fan, you have missed your mark for planning and will have other concerns

                I'm running a DSATX so the extra load isnt a concern, its just whether I can face ripping everything out again to run more wiring to the boot

                    Hehe, i'm pretty sure my car electrical system wouldn't now be considered proper but i'm sure your right
