Is the radiator-esque heat sink made of copper or aluminum? MBA 2018

Hi!

I’m getting quite high temps on my mac and was wondering if i can try apply liquid metal to the heatsink. I opened my macbook air and found a heatsink that looks to be made out of aluminum, but im not sure and can’t seem to find any information of whats it made of on google.

Okay so no way to use liquid metal? Is arcric or grizzly paste best? I’ll have to go to the store tomorrow and buy some to use instead of metal

I replaced my paste with arctic silver 5 and seems to be running a bit lower now. Switch to safari as well and this seems to drop the temp by like 10C so all good now :)

How much is good thermal paste on a macbook? I put as much as in the picture but when i took it off it had so much more paste. Like apple put sooo much more paste.

Either one is good. There really isn't any difference between them.

It's not always easy to determine how much is the right amount. You want enough to just cover the CPU can and not ooze over. Yet, you don't so little that the edges aren't covered so you get the maxim coverage to the heat sink. Do remember the paste is not intended to be thick its designed to fill the microscopic pits in the metal and transfer the heat across the void of the two metal surfaces.

The way you lay the paste is also important! I prefer the dot smack in the middle, that way there is no risk of capturing an air pocket as you press the heat sink down. A line also works when the chip is more rectangle, just becaseful you don't put to much at the edges.

First, do not use liquid metal TIM on your laptop!

You should fully clean the old paste and apply a fresh coat of thermal paste I would use the following:

Arctic Silver ArctiClean
[关联产品丢失或禁用： IF179-010]

Once you’ve put things back together I would install a good thermal monitoring app like TG Pro it will allow you to monitor the different sensors more effectively. Take a snapshot of the main window and paste it here for us to see if you are still encountering thermal issues 在已经存在的问题里加入图片

On the most part your system will get warm and has sensors which will shutdown the system if the system gets too hot.

Often times I see systems getting too hot when the systems resources are maxed out for the task they are doing. As an example high def video games or a full drive so the system does not have enough free space which gets into not enough RAM or large enough storage. The MacBook Air is not a deep gamers box or designed for deep music or video editing.

Note: Liquid Metal TIM has a tendency to travel which is why no laptop should use it. Even when used in a desktop one needs to monitor the orientation of the CPU chip as it needs to be level horizontally.

It also is corrosive with some metals and the heat sink Apple uses is an alloy which will be damaged by it.

Once you start messing with it you will lose you warranty. If it is overheating, take it in for a warranty repair. Also on any Apple product that I have problems with in the first year, I take out an additional 2 years of warranty with Apple Care!

I live in the EU, would it still apply? As i did not damage anything i don't think they can make me pay for the repair if it was not broken by me?

I got warranty from a third party anyways so i think they will still repair it but i will have to pay 100 euro in case it breaks.
