When you say overheated do you mean the mac shuts off or it's just feels hot to the touch?

inside the fan and on the board, old inefficient thermal paste can cause overheating. Insufficient RAM may also cause overheating.

Open the laptop and use some "canned air" to blow out the dust from inside the fans, the cooling slot and off the logic board. Do not touch the heat sink at this time, as it's a rather touchy DIY job. Reassemble the laptop but do not screw down the top case just yet. Perform tasks that used to overheat the box. If overheating no longer occurs you're good to go.

You should max out the RAM for your machine.The MacBook Core 2 Duo shipped with 512 MB or 1 GB of RAM. If your MacBook is still running with only the stock RAM, upgrading will provide a dramatic performance boost at minimal cost. Upgrading to the maximum (3 GB for Core 2 Duo, 4 GB for Santa Rosa or Penryn) can be done very easily.

If no significant change occurs in the overheating you could go the next step and replace the thermal paste. Take care with the disassembly/reassembly of the the small connectors, they are easy to damage.

As far as being obsolete goes. IMnsHO if the computer still performs the functions for which you purchased it, there's no need to change up to a newer box. If/when you purchase a piece of software or hardware that requires more power than you currently own, that would be the appropriate time to upgrade.

If this answer is acceptable please return and mark it.

Good Luck,

As I would say it, only this answer was better.. 1+ from me!


This is a very complete answer, and you should do what he says, but and more thing... You have to understand that all model macbook and macbook pro usually overheat a little bit, more than other computers, so not always this is a problem that can be fixed, and make sure that you are using the computer in a normal environment with normal temperature. Good Look :)


The only thing i have to add is that its best to remove the fan for cleaning. A lot of dust can gather on the exhaust side and cannot be removed with the fan in place.

I find that the MBP fans default to only 1000 rpm until it gets insanely hot.

First thing thing I would do (after blowing out the dust... well OK, the second thing :-) is to install iStat Menus (version 2 is free, version 3 costs). Then see what your actual temps are while running different tasks. iStat can also display your fan RPM's and you will see them both at 1000rpm.

Next, install fan control. This is a great utility that can adjust the fan profile to something a little more agressive that will substantially reduce temps. Play around with it and find the right balance of temps and fan noise. It is very easy to use. Linked below.

At least at the end of these steps you will be able to tell exactly how hot your Macbook is getting.
