    17V mod on fan?

    Is it a no go? I know it'll be noisy but it should hack it right. This is an 80mm we're talking about. Running it over 12V and -5V.

    I think I'll try it outside the comp before I try it with mobo and everything plugged in...

    Why you wanna do that? Its gonna sound louder than a Delta or Tornado at those volts.

    Are you on one of ur crazy overclocking missions again kez?

    Crazy mission again iMc, lol.

    I've got an old 80mm wired across -5V and +12V right now - on an old PSU.

    Seems to be running OK...

    The fan will most prob burn out. The motor isnt rated to use that voltage. Wait for the smoke

    Yeah I know it'll probably burn out, but to be fair, I bet it can hack it as it's only 5/6V more (ok 50% overvolt then, lol.)

    Just tried it across the -12V and +12V rails (ie 24V.)

    I got a ton more airflow out of it - and took a reading of the voltage...

    Came back as 40V - I think the -12V rail on the PSU is poorly regulated when there isn't much load on it, LMAO.

    edit: FYI I'm testing this with an old quiet fan from a PSU - I'd love to see what happens to a delta...

    LMAO 24V (or whatever insane voltage this PSU is giving out) is VERY noisy! And there's an awful lot of airflow!! I'll do some videos with comparisons in a while
