    Is there anyone using Lion, also installed smcFanControl here? I clean installed Lion, then installed smcFanControl 2.3. When I use smcFanControl at 10.6, the lowest fan speed was like around 3000, give or take; I noticed the lowest fan speed under Lion now is like around 4700. Is it just me or someone else has the same situation like this too?

    But, one thing for sure, my MBP is much cool under Lion than before.

    Hmmm, it might be that your computer is working harder. I can't say that mine is different because my default fan speed is always very high, even in snow leopard.

    I have Lion and SMC Fan Control. No change from SL - 2000RPM

    For each machine, Apple has determined the minimum fan speed and mapped an increase based on temperature.

    It's possible that for your machine, Apple changed that min and map... under Lion.

    SMC FC is designed to not go below default minimums based on the OS.

    What model do you have and - when you say "minimum" do you mean lowest it's always running at, or lowest you see possible on the slider on SMC FC?

    i have noticed that my computer used to run at 194 degrees while playing games like wow and starcraft and now its only running at 150 while playing them.

    thank you so much, 8Core.

    My MBP is refurbished and originally released at the end of 2010. i5 CPU and 4G RAM.

    By "minimum", I meant the lowest i saw on the slider on SMC FC.

    I am running lion with SMC and it defaults to 2000 and goes up as needed.

    I am experiencing exactly the same and it is very annoying the noise. I used to be able to reduce it to 3000RPM but as smc only allows minimum of default value am stuck at 4500.

    I really want to reduce it as at default I am running at 40 degrees anyway.
