    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

    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
