    I had this MB:apple: for over a year now, It was running at a avg temperature of 50 C, but recently it's getting hotter and hotter, now it's running at 70 Celsius constantly if i do not increase the fan speed.

    How can I lower the temperature?

    P.S. I upgraded from Leopard to SL last year.

    Many Thanks.

    Or you can use a guide from iFixit, and open it up, and clean out all the dust. Or if under warranty, bring it to the Apple Store. The Unibody Aluminum MB, Is easy to open. Just remove the battery, and hard drive. Then remove the screws around the border.
