    I had some issues with the regular updater for 10.5.7, so I installed the Combo Updater on top of it. I noticed that the default fan speed for my MB has gone from 1800 to 2000 RPM. Has anyone else noticed this?

    If so, did you use the combo updater?

    Why on earth does SMC make it look like the default is 1800? I of course juiced my default on my macbook (with smc installed) up to the 2000 mark but wondering why SMC does this and what the default fan speed for the 17 inch UNi is?

    There is a discrepancy in the minimum speed listed for the Macbook 5,1 in the machines.plist that SMC uses between two of the download locations for 2.2.2

    Interesting. I had iStat installed previously and noticed the 1800 RPM was lower than on my old MBP (2000 RPM). Then when I installed 10.5.7 I noticed it was just slightly louder, even at idle. So I checked the fan speeds (opened SMCFanControl) and then saw (and heard) the fans go from 2000 to 1800.

    What is the real value?

    I was using my 2.4 GHz Unibody MB at 1800 for the last 1.5 months without issue.

    My Unibody MacBook Pro default is 2000. I don't think the update up'd it. Try resetting SMC.

    Just for the sake of reiterating, I also have a 2,000RPM (always have) fan on a 2.4GHz MacBook. Sometimes it drops into the 1900's. What is the purpose of SMC? Wouldn't Apple put their notebooks at a comfortable level based on the usage?

    It's supposed to be 2000rpm, its also supposed to be 2000rpm in smcfancontrol but one of the download locations for it has an incorrect setting in a plist for Macbook5,1 that has it set the fan to 1800rpm.

    The fact that it can do this at all has made me remove it.
