It’s not really a efficient heat sink since it’s just a big slab with no fins to actually cool itself down. Now it’ll heat up the whole chassis and then stay hot. It also doesn’t look like the metal piece on top of the CPU is seriously connected to the chassis (like with direct contact and thermal paste)
- dev_tty01 4y agoNo, a small finned heat sink with no air movement would be worse. They are spreading out the heat to move it out via a large surface area of the metal case. I'm guessing the paste wouldn't help much since the heat flow density is fairly low. Think of it this way, the thermal resistance per sq mm is relatively high, but the total parallel thermal resistance is still very low because of the large area. Don't forget, this machine is focused on the consumer mass market, not the high performance market. It will never break a sweat for the vast majority of typical use cases. Even when throttling a little bit, it still vastly outperforms the Intel MB Air it replaces. Get a 14" MB Pro if you really want incredible thermal performance.

- threeseed 4y ago> It also doesn’t look like the metal piece on top of the CPU is seriously connected to the chassis It's not supposed to be connected. You are describing the hack that some people do where they add a thermal bridge between the two. Yes you get better performance but at the cost of serious injuries due to the significantly increased heat being directed to your lap.
