Replacing the heat sink?

I was reading about how to replace the heat sink for my macbook pro 1260 model. I looked and it said that ifixit has a replacement heat sink that does not come with temperature sensors. Can you use the sensors that were on the old heat sink for the replacement one?

Is this a good question?

You do need to have the sensors functional otherwise the system will not engage the fans.

Why are you swapping the heat sink?


Can you use the sensors from the old heat sink? The computer is 4 years old and it heats up very quickly. I get readings of 180 degrees with moderate use.

Joe - Replacing the heat sink won't fix this kind of problem. Unlike a desktop system were you could put in a larger unit there just isn't any room or alternative heat sinks that offer better cooling than what you already have now.

You need to clean off the old thermo grease and apply a fresh coat on the CPU & GPU units so heat is better able to dissipate into the heat sink. Make sure to use a good quality thermo grease. You will also need to clean out the heat sink fins of any dust as well. Don't forget to clean the fans and make sure they are running.

Lastly, you should look at your applications and any OS add-on's to make sure none are running when they shouldn't (a common cause of over heating).
