Correct Cooling Procedures (Fans)


I have a MacBook Pro Late 2006 (Serial; *******WGK) and I dont know how to cool it correctly.

When I use a external Monitor I close the Lid, power up and then open it again so external Monitor works and MacBook is open But since that time it got very loud. And now its 68 Degrees Celcius, SOmetimes its over 75. Is it normal or too hot? How can I stand the MacBook Correctly?

It is on my lags now and underneath is a TV Program Guide so it gets a bit colder but fans are very loud!

Just like any system that needs cooling it requires a source for cool fresh air.

In the case of the Mac laptops it's through the keyboard. So when you block the air from entering through the key board the fans need to work harder. I would recommend leaving the lid open about 1/4 inch or more to allow the air to flow.

The other factor here is how hard the system is running. Watching a TV show or movie is a heavy compute process so it creates a lot of heat. Using Flash or accessing heavy graphic elements on a web site can likewise push your system.

If your system is clogged up with dust this will hold the heat in and cause the fans to work harder. Cleaning out your logic board and fan of any dust buildup will help. Lastly, redoing the thermal paste between the CPU & GPU units and the heat sinks will allow better cooling if the current paste is dried out or not correctly put on. There is a bit of skill here in doing it correctly. you don't want to much or to little, and you don't want any air bubbles either.

I would recommend getting 'Temperature Gauge' and 'Monitor Deluxe' apps from the App Store to monitor your system with the lid open Vs closed so you can see the difference in its' temp. Use Monitor to see whats happening with your CPU load in case you have something running wild.

In order of increasing difficulty: - Blowing the dust out of the unit, directing a fan at it (using a cool pad or resting up off flat surface), using 3rd Party FAN app. can make the fans come on sooner - that will help cool it too.

If you're DIY inclined replacing the thermal paste ( a rather difficult DIY job) can all make the machine run cooler...

Apple MacBook "Core 2 Duo" 1.83 13" Specs

Identifiers: Late 2006 - MA699LL/A - MacBook2,1 - A1181 - 2121

My first guess on this would be clogged heat sink ports. Here's how to get to the heat sink and be able to clean the vents: MacBook Core 2 Duo Heat Sink Replacement I would also replace the thermal paste as machead recommended. Here's what I use: Arctic Silver Thermal Paste

Use compressed air to blow out the fans and interior

If you're not using 10.7 with access to the Apps store, go here for Temperature Gauge download:
