Question about Apple MacBook Pro Notebook

2 Answers

My 2001 MacBook Pro fans run almost constantly, while my previous 2009 MacBook Pro fans seldom ran. Why is that?

My 2009 MacBook Pro had 8GB of RAM and my 2001 MacBook Pro has 16GB of RAM. It's annoying how often and how long the fans run on this 2011 MacBook Pro. I run apps like: Google Chrome, Mac Mail, Excel, Word, Dreamweaver, Safari, Firefox, iTunes, Parallels, Windows 8, Photoshop.

I had to chuckle, because many MBP users actively seek out applications to make the fans run more often and more vigorously. It seems that early models of MBP would quietly cook themselves to an early demise.



You should follow Ted James\' advice regardless - it\'s easy to do and worth doing whether that\'s your problem or not. However, I had a similar problem with my MBP and found that it was a browser plug-in that was the CPU and running the system hot. If it\'s a software package making your mac run hot, that\'s a little more tedious to troubleshoot, but still pretty simple. First - try this simple step: While your mac is running the fans (misbehaving) start the Activity Monitor app - which is in your Utilities folder. If you prefer to use LauchPad to start applications, then you may need to look for "other" start typing "activity" in the search box, b/c the utilities are not shown by that name in some newer OS X releases. Once Activity monitor is running, select the CPU "tab" at the top or bottom of the app. Now you should be able to see how busy your system is in a moving graphic at the bottom center of the app. If your CPU is running at nearly full capacity, have a look at the column called % CPU. If the process name a the top of the list is contributing the majority of your % CPU, then that is the candidate for an errant application overheating your Mac. I\'ve attached a screen shot of Activity Monitor working on a quite system with almost no activity.

It should be obvious, but the next thing to try is to exit or kill that application and see if that allows the fans to spin down.



Hope that helps.

Your cooling fan is clogged with dust, not allowing enough air to circulate through it. Use compressed air and blow out the vents. The fan constantly runs because it isn't getting enough cooling.

Testimonial: "When I upgraded the RAM I used a vacuum to clean out dust, however that didn't fix the near constant fan use."

I am running OS X 10.4.11 and would like to upgrade my operating system?


Please provide more information.
To what would you like to upgrade it?

Since OSX Mavericks was just announced, I'm going to assume that's what you're wanting to upgrade to.

Not all Macs can run Mavericks.

Mavericks Capable Macs

Mavericks, like its predecessor Mountain Lion, requires one of the following Macs with at least 2 GB of RAM and 8 GB of available hard drive space:
  • iMac (Mid 2007 or newer)
  • MacBook (Late 2008 Aluminum, or Early 2009 or newer)
  • MacBook Air (Late 2008 or newer)
  • MacBook Pro (Mid/Late 2007 or newer)
  • Mac mini (Early 2009 or newer)
  • Mac Pro (Early 2008 or newer)
  • Xserve (Early 2009)

If your Mac isn't one of the ones listed above, you won't be able to upgrade.

If you have an iMac, MacBook, MacBook Pro, or Mac mini model that was originally released in Early/Mid 2006, the latest version of Mac OS X your system supports is Snow Leopard.

Could I use MacBook Pro 1G RAM (hynix 1GB 2Rx16 PC3-8500S-7-A1) to upgrade my T400 2G RAM to 3G?


Hello thx5,
It depends on how the 2GB in your T400 is currently configured. If the 2GB in there now is just one 2GB stick of RAM then yes you can add the other 1GB stick and then you will have 3GB of RAM installed. If your 2GB is two 1GB sticks of RAM (which is more likely to be the case) then the 1GB stick you have from your Macbook Pro isn't going to help.

Note: your laptop can handle up to 8GB of RAM via two 4GB sticks.

Hope this helps, if so please leave some good feedback. Thanks.
