Fans in MBP going like the clappers

    I have a late 2006 MBP - 2.33 GHz, 4GB or RAM (although due to limitations with that particular era MBP it only recognises 3GB) and a recently upgraded hard drive - 500 GB 7,200 rpm Seagate and 10.6.2 Snow Leopard.

    I notice it runs very hot and the fans can become very, very loud. Even with just Firefox open. (Also with some Rosetta apps such as MS Office 2004).

    This also used to happen before my recent upgrade to 10.6 (previously 10.4.11) and new 7,200rpm hard drive. At the time I though it was because I had less than 5% free space on my old disk and I thought the swap memory operations might have caused a lot of disk churn driving up temps.

    But now, who knows? Is it the new, faster disk that makes it run hotter? Or the OS? Because it doesn't take much to kick the cooling fans into high gear my useful battery life has plummeted. It devours a full battery in between 60 and 90 minutes. And this battery is a replacement bought only a year ago. Software update doesn't show that it's due any firmware updates..

    Puzzled.

    Maybe when the hdd was replaced the temperature sensor wasn't affixed properly. Also a 7200rpm drive would create a lot more heat than a 5400rpm.

    Alternatively, open Activity Monitor and check if there's a misbehaving b.g. process. Some third-party apps/drivers are the equivalent of viruses.

    Also, download a temperature monitor app and see which fan is going crazy.

    Not sure if its a similar issue, but previous iMac models occasional had a bug where the fans went like mad for no reason. There was a fix on the apple site.
