Why Macbook heats up to 100° even from a simple js animation?

Question

JavaScript

There is an MBA 2011 with OSX 10.8 on board. Previously, I didn’t use it much, but now, due to traveling, I use it as the main working tool. Recently I noticed that while working with scripts that involve some kind of animation, the Macbook starts to get very hot and make noise with coolers. I decided to install smcfancontrol and look at the temperature and saw that when working with even a simple nivoslider, the temperature rises to 80°C, and if the site uses canvas animation, the temperature rises to 100°C. The normal operating temperature is around 60°C. I decided to take it to the service, to clean it and replace the thermal paste, as a result, the operating temperature dropped by 5°C, but under load it still crawls to 100°C. On the desktop iMac, the temperature almost never jumps over 80 °. Is this normal for internal components? It is clear that this is a laptop and here the cooling is not the same as on the desktop, but still warming up to 100 ° from a simple animation is foolish. What happens if I launch something more serious, like some kind of game?

Answer 1

Heating up to 100 - this should burn your hands. Plus, at the laptop itself, at a temperature of about 100, the fuse should work, and the laptop will freeze / cut down. Is there such a thing?

Answer 2

MBA 2011 has always had an issue with elevated temperatures. You are not the only one with this problem. It's one of the first MBAs and they were also experimenting with low power laptops. The design is not perfect. My MBP with HDD does not heat up like that. Even when compiling Xcode, it eats more resources than yours.
Write it all down constructively. First, try updating to at least 10.10. If the problem remains and is critical - change your air to something fresher.

Try to look at the maximum operating temperature for your processor on the Intel website (for some processors, 100 is relatively normal, for some, you need to run to the service). My MacBook Pro 2014 heated up to a maximum of 100 degrees just when compiling GCC, for example, and the operating temperature is just about 60. Plus, I suppose that this may depend on the browser. When I tried to play with canvas animation I got a very different load in different browsers.
