    My 2.53 GHZ Unibody is very loud with one of the fans today.

    Anybody seen this?

    the RPM sensors don't show anything unusual just the noise inside
    is much much louder than normal.

    So the fans are spinning with 3000 RPMs but it sounds like 6000 RPM?

    What software do you use to monitor the fan speed and CPU temperature, and what software do you use to control the fan speed?

    Fan control didn't seem to do a whole lot for me.

    iStatMenus show RPM as 2000 rpm but the left one is definately all of a sudden louder and I noticed post 10.5.7 fans hitting 4500+ rpm plus sporadically.

    smcFanControl also doesn't do anything when launched for me.

    What would I do in Fan Control? doesn't seem to let me control each fan independently.

    See attachment for the sound. Turn up your volume.

    Yeah I did that and reset the PRAM.

    SMC is take AC adapter out, battery and then hold power down for 5 seconds right? The issue is that you never get any feedback that it worked.

    If I remember correctly, the procedure has changed with the new Pros, it is now done like the MacBook Air.

    Right Here

    i suggested fancontrol to help experiment. to diagnose the problem. if your fan sensors i truly kaputt then fancontrol would be able to tell you that

    When I read that document I figured the 15" Unibody was under

    MacBook, MacBook Pro except MacBook Pro (17-inch, Early 2009)

    Yeah something is odd because when I launch it it does literally nothing. I don't see any GUI on my machine. iStatMenus shows the RPM as normal.

    hmm then i would say either your fans are messed up or that it's something else. are you sure there is no CD in there or that your HDD isnt running really fast. i hate to ask that question but it happened to me once. i was like what is up with my fans and after a while i realized it was a South Park DVD spinning.

    My machine doesn't have a CD inside it right now and has an X-25M (160 gb) instead of hard drive so I don't think it's the hard drive. The only thing it could be since it's at the back (near the screen) left hand corner area and that's where the left fan is. There's nothing else that would be rotating in that area.

    just a thought. have you taken the back of to see if something is obstructing the fans?

    Just a quick update I took it to the genius at the applestore and he immediately agreed with me that something wasn't right with the fan and the noise it was making. They will be swapping out the fan. I hope they do both since you figure if one has gone the other is soon. He said something about the fans being magnetically aligned and sometimes they come out of alighnment and can become unbalanced and result in friction.

    In anycase I'm hoping my machine with have two new fans in it tomorrow. I only hope that Apple takes care when taking out the screws because I know from having seen the machine with the back off earlier that it's a relatively easy thing to replace providing you have the part. Since it's under warranty I'd prefer Apple did the work but I still have some concerns about my machine coming back in the spotless condition it went in.

    Just got a call from Apple Store today telling me that they stripped one of the screws and marked my case when trying to get it out and that they have to replace the bottom case to correct the problem so I guess my fears were warranted afterall and they'll be a delay until they get the parts they need.

    Update:

    Apple got the parts they needed and gave me a call to say that all the work has been done and the machine is ready to pick up today. This is the same day I got the call saying they needed to order parts so despite having screwed things up they have gone out of the way to fix things in a timely manner.
