What's your smcFanControl "ideal" minimum speed

    I'm playing with various minimum speed settings in smcFanControl, basically looking for the best "middle ground" of speed vs. resultant temp. Right now, I'm at 5000 rpm/115-120F (46-49C), which is about 30F/18C off the unaltered temp.

    So, what's yours?

    Do they get loud at all at any of these speeds (3k and up)?

    I only hear mine above 5,000rpm. I run the fans at 2,500rpm and it keeps the temperature ~47-49C.

    I don't suggest using that at all.

    Get rid of that. It'll ruins your fans. It did it to mine.

    You the iStat widget to monitor your fan speeds.

    I can hear it at 3k, but it's not a bother, and I sleep with my MB running on the desk beside my bed. So it passes the sleep test for me. I've had multiple laptops that haven't in the past.

    Are you saying that smcFanControl damages the 'Book? That's the first I've heard that from any source. Details, please!

    For some reason I cannot go any lower than 3500 using Leopard while 1800 was the minimum in Tiger.

    Anyway, 3500 holds the temps on 37c while downloading and browsing. Much better than on Tiger really. I guess a cold room also helps.

    2.33Ghz / 15" running 10.4.11 here. I usually run it with the minimal RPM (2000) at ~47C (that's 177F apparently). When I use matlab intensively I increase the RPM to 3000, because it can get to 80C quite rapidly. On this machine it gets audible at about 3000, I think.

    4k minimum speed keeps my MBP hovering around 100ºF, though that is the internal temps, not the temp of the external case. It is quite comfortable now:) I just wish I could undervolt it also...:rolleyes: I've undervolted it in Win XP and that works wonders. Running ANYTHING in Win XP makes the laptop get VERY hot.

    Sorry to dig an old thread up, I'm now on 10.6.3 and the min I can get on my Mid 2009 MBP 15 is 4651--loud and annoying. Any idea how to put it below that without having to shut down smc fc to deactivate it and then restart?

    Thanks

    Mine is 2000 default,2500 for light work,and 3000 for heavy load,if it's really hot and I'm using it in my lap I may turn up the fans,it depends.
    I used to use fan control but smc is much nicer because you can have the systems default fan speeds with just a click.

    Hmm? Are you saying just having the program open in my menu bar ruins the fans? Or altering their speeds ruins it? I like to keep it open just to see the default fan speed and temp.

    Completely agree.

    Just get the old (free) iStat and let your Mac manage the fans.
