I naively picked up a late 2018 air without considering the thermal aspects of the performance. It sounds obvious but I totally missed it and bought on basis of the benchmark numbers, make sure to look at the thermal performance under sustained loads. Notebookcheck do a good job at deep diving on this in their review https://www.notebookcheck.net/Apple-MacBook-Air-2018-i5-256-....

It's basically passively cooled! There's no heatpipe connecting the fan to the CPU so it kicks up to max all the time trying to cool it but can't make much of a dent on the temp. Really mind boggling.

I had to switch back to my old pro machine and felt like a bit of a berk for not reading up on that aspect.
