When I run SMC my fans kick to 4000rpm and SMC shows that my default speed is 4000rpm, I cannot put it lower then 4000 only higher. I have tried uninstalling the program and reinstalling. Any suggestions?

What model Mac do you have?

2010 macbook pro i5 2.4 ghz

you need to quit SMCfancontrol, then delete the plist for it...
com.eidac.smcFanControl2.plist
it should be in your home folder -> Library -> Preferences
when you run it again, it should re-create that plist with default settings for your machine, including 2000 rpm minimum settings. -
I had it working, but I reinstalled OSX and now its doing this. -
This is coming from a person who is just about to receive his first ever Mac in two days so, I might sound stupid and make a complete fool of myself but...
Could you manually change the settings in that preferences file? Are they writable text files or is it just not that simple in OS X? -

you can open the plist up and find the entry for the fan speeds and manually change them...
I did this on my old Mac to downspeed my fans to 1000rpm... but sadly that didn't work on my 2010 model, even setting for 1000, they keep going 2000. Somehow SMCFancontrol is just not detecting your machine right when it runs. You do have the latest version right? -

To convert the binary plist to XML...
Code:plutil -convert xml1 $HOME/Library/Preferences/com.eidac.smcFanControl2.plist
Code:plutil -convert binary1 $HOME/Library/Preferences/com.eidac.smcFanControl2.plist

Okay well I have no idea what any of that means, I just got a mac so i'm not familiar at all with the os, so can you explain that in order for a OSX noob to do it.

If you copy and paste that first command I put in, it will convert the plist (preferences list for a program) to an XML format so you can edit it easily. You can then open it up in TextEdit.app and look through it (it'll be XML formatted so it'll have tags and stuff int here you have to figure it out). You'll find the place where it has settings about fan usage... you can edit them carefully and save and exit and it should have changed.
close SMCfancontrol then open Terminal.app and copy and paste these lines in separately.
Code:plutil -convert xml1 $HOME/Library/Preferences/com.eidac.smcFanControl2.plist open -e $HOME/Library/Preferences/com.eidac.smcFanControl2.plist
looking at that picture, you'll see a couple settings where minspeed is set to 2000 and maxspeed is set to 6200. Make sure your min speed in all entries says 2000 and not 4000. if it says 2000 already... then I'm not sure whats wrong.
if you want to make it easier.. you can install Xcode tools... then you can double click and open a plist super easy in a reader made to look at it all correctly... no tags and junk, and no XML conversion needed.. -

That is what im getting now ?? It does not show any min or max speeds like in the picture above -
What version of SMC Fan Control do you have?

Is there something similar for win7 in bootcamp? since most seem to using that for gaming id expect people to force the fan on there too?

great thanks!

Anyway that we can set certain RPMs to activate at certain temperatures, like it activates by itself to keep it constantly under X degrees?
Also what are normal temps for a macbook 2010 320m?
