    What is the minimum fan speed for the 2011 Sandy Bridge MBPs? I tried smcFan and the lowest it'd go is 3000rpm. smcfan used to go to 2000rpm for old MBP. iStat Menu is still able to go to 2000rpm on my NEW MBP. Why the discrepancy on between the two? Has the baseline speed been changed?

    My 2011 MBP goes down to 2000RPM and up to 6200RPM according to smcFanControl. My previous 2009 MBP had a max of 6000RPM. That extra 200 really pushes it that extra mile. =P It needs to, considering how hot the i5 gets in this thing. Ugh.

    interesting. here's a screenshot of smcfan I took. As you can clearly see, won't go lower than 2000rpm. Any ideas?

    you can manually edit the file SMCfancontrol uses to create your own custom settings...but I really don't know why you 2000rpm isn't there by default.

    Try Fan Control, which I think is a generally nicer app than smcFanControl. It actually allows you to drop the fan speeds lower than 2000 RPM, then have it gradually increase with temperature, rather than have it hit 90C then the fans zoom up to 6200 RPM. I'm just doing basic browsing now, and my fan is around 1350 RPM, with temps around 50C, which is perfectly normal.

    SmcFancontrol I just have settings for 2k, 3, 4k, 5k, and max. If I'm doing anything I usually just leave it on 3k.

    I started having issues with smcfancontrol. Before I could go down to 2k, now it won't go below 3k. I have stopped using it, as I have read that I really don't need it. The MBP does all the work and changes it when needed.

    At idle my base 2011 15" MBP fans are at 2000 RPM. It's the quietest laptop computer I've owned.

    Shouldn't be noisy at 2k.. if it is, something is wrong with your fans.

    If you find 2k RPM noisy, you either have bad fans or you are hearing your hard drive, some of them make a constant, wooshing fan-like sound.

    My 2011 i7 2.2Ghz MBP is near-silent at 2k RPM. The only noise I hear is the hard drive in a quiet room.
