What is an acceptable temperature
I've recently changed the thermal paste on this to try and get the temperature down, however it still runs at about 100 degrees Celsius. Is this the normal cpu temperature for this laptop?

Hi,
in fact I do have the exact same Macbook Pro, so I want to share my current temperatures with you (@ approx. 25°C ambient temp):
Although my Macbook neither was in heavy load nor idle, I think it is fair to say, that your temperatures, in case you did not run heavy calculations in the background, are way too high!
What were the temp values like before you changed the thermal paste? Which paste did you take and how much of it did you apply ;-)

It was probably about 10 degrees higher! I used Arctic mx 4, and used the spread method. Maybe it would be worth using a different method?
Okay, I do have exactly the same paste in use - back then I did it according to the following method (unfortunately in German, but it shouldn't be hard to get it translated:

Especially make sure you also clean the copper parts of the heat spreader as well as cleaning the residue of the old paste with 99% alcohol. I would further highly recommend to take the fan ducts cautiously apart and use some qtips with 99% alcohol to clean the remaining dust away. Quiet some work, but it is worth it!
After this procedure your Macbook will be back on duty for hopefully quiet some time :)

The average CPU temp should be about 50-70°C. I would recommend checking if your fans are spinning if they are check if they are dusty and blow them out with compressed air. If they aren’t, check if the cable is damaged or if the fan is broken.

Lets get a better idea on what's happening, Install this great app TG Pro You only need the free version.
Take a snapshot of the all of the sensors (you'll need to adjust the window size so all of them can be caught in one snapshot) Don't forget to get the fans as well. Post it here for us to see 在已经存在的问题里加入图片. Ideally, we need one just after starting your system (about 20-30 min running) before running any apps (baseline). Then do a second when the system is running hard when you think it shouldn't be.

@lividpenguin - Not seeing all of the sensors! You'll need to alter the window size width down as well as slide the fan window down a bit so the sensors on the lower area can we seen within the snapshot.
Let's try to get another capture.

Ok, thank you for all the replies on this thread! Through everyones help i discovered that my MacBook was indeed running way too hot. I took someone’s suggestion and changed the thermal paste again but used a different technique that meant the coverage was hopefully better and 48 hours later it seems the temperatures have gone way down. Thanks again!
