    I'm running a refurb'd aluminum iMac (specs in sig).

    I just downloaded smcFanControl after seeing posts here about it.

    I was just wondering whether there was any harm in keeping the fan speeds pretty high (near their max). I realize that the default Apple profile will (theoretically) work fine, I'm just curious as to if there are any downsides to keeping the fans at high RPMs.

    They will run down faster, but that most likely won't really become a factor. The computer will be louder.

    Ok, thanks.

    I happened to accidentally lose the default profile, because being the genius that I am, I accidentally overwrote it.

    Does anyone happen to have the default numbers handy?

    Higher speeds mean more dust,a little more fan wear and noise.

    Default speeds are 1000 OD,1200 HDD, 1200 CPU.

    Nice, thanks.

    One more question...

    I have an smc profile to use after I play a game or something. After I'm done and my temps are back to normal, how do I get the fans to return to their normal speeds after I exit smc?
