Where I think the MacBook Pro could do better is if they adopted more of a vapor chamber strategy for the heatsink, but as you mentioned the radiators are probably going to be the limiting factor, seeing as there's really not a huge temperature delta going on here. Measurements by Notebookcheck seem to suggest that the MacBook Pro is already doing fairly well compared to PC OEM solutions, especially given the size of the enclosure and the fact that unlike Asus in the Zephyrus, they're not using 12V server level 60dBa fans in a laptop. Modern Intel notebook processors like these are likely running close to 80W and 65 steady state - They've got up to 8 cores to do this. People are trying to put CPU+GPU+RAM packages that are anywhere from 25W to 45W TDP in laptops that are physically too small for them. At least the 12 inch Macbook from a few years ago which was truly fanless uses an appropriately low powered CPU.ĭisclaimer: used to do systems engineering for a server manufacturer a long time ago, after you've gone through a dozen iterations of ways to mount skived copper heatsinks on dual socket motherboards in 1U cases, with various fan solutions, you realize that everything that is not acoustically terrible is some sort of compromise. Whenever I see a laptop with a >15W TDP CPU in a super slim package with a tiny heatsink/fan unit, no matter if it's from Apple or another vendor, I'm very suspicious.
Or the management/product design group has overridden the input of the people who actually know how to design thermal solutions, because the laptop CANNOT be 2mm thicker. If I had to guess they know what they're doing engineering wise, but they're taking a calculated (and poorly thought out, in my opinion) risk that a small percent of people will regularly peg the cpu at 100% usage, and they're further relying upon clock rate throttling and the cpu die thermal sensor to keep things from melting down.
