In recent hardware release cycles, Apple has focused on one very specific theme: How to control heat in fanless devicesThe iPad Pro and the most advanced iPhone models have been receiving internal revisions focused on improving heat dissipation to better utilize the power of Apple silicon.
However, everything points to the next MacBook Air with M5 chip would maintain the same general strategy This new model differs from the current generation: a very thin and light laptop with passive cooling and, according to leaks, the only significant upgrade being the processor. For many users in Spain and the rest of Europe, this opens up an interesting debate about the balance between design, sustained performance, and temperature.
From iPad Pro to iPhone 17 Pro: the thermal stress that doesn't reach the MacBook Air
In recent years, Apple has been incorporating specific cooling improvements into various products, prioritizing thermal stability for Avoid overheating and performance throttlingThe most striking case has been that of the iPad Pro, where internal changes have been introduced aimed almost exclusively at controlling temperatures.
In the recent iPad Pro, the company decided to add graphite sheets on the main casing and copper applied to the Apple logo areaThis combination allows heat to be distributed and dissipated more evenly, resulting in a thermal improvement of around 20% compared to the previous generation, according to data from Apple itself.
In the iPhone realm, the problem became especially visible with the iPhone 15 Pro, heavily criticized for its temperature spikesThe response came in two waves: on the one hand, an internal redesign of the iPhone 16 to improve heat dissipation; on the other, a much deeper revision with the iPhone 17 Pro, which integrates a vapor chamber and an aluminum unibody chassis that acts as both structure and heat dissipation element.
Thanks to these steps, both iPad Pro and iPhone 17 Pro now have clearly more advanced passive cooling systems than in past generations. And that's where many users wonder: if this effort has been made in tablets and mobile phones, why isn't the same philosophy applied to the MacBook Air?
The MacBook Air redesign and its thermal limits
The big change for the MacBook Air came in 2022, when Apple released a a thinner and lighter body, accompanied by the M2 chipThis redesign not only affected the aesthetics: it also brought about a significant change in the dissipation system, which went from a larger metal heatsink to a much thinner graphite sheet, without a "real" heat block as such.
This decision had a direct consequence: MacBook Air with M2 tends to overheat earlier than the previous model, especially when subjected to demanding workloads for extended periods. The system remains completely passive, without fans, and relies on the graphite to try to dissipate heat as quickly as possible, but its margin is limited.
With the advent of M4 chip With the iPad Pro and the introduction of copper in the logo and internal improvements, many interpreted that move as a hint of what might be coming later for the brand's most popular laptop. However, The information circulating about the MacBook Air M5 indicates that the main, or even only, new feature would be the processor, with no notable changes in the thermal system.
Several technical possibilities are on the table. Apple could opt for something similar to what it already did in the iPhone 17 Pro, incorporating a vapor chamber or other more advanced passive dissipation systemHowever, for now, leaks insist that the approach for the MacBook Air M5 would be continuity: same design and cooling philosophy, but with a more efficient and powerful next-generation chip.
The underlying problem is that, although Apple Silicon improves generation after generation, The MacBook Air's thermal margin doesn't seem to be evolving at the same rate.If the chassis and cooling system remain virtually unchanged, each power increase risks further shortening the time the system can maintain its maximum performance before reducing frequencies to protect itself from heat.
What would a MacBook Air M5 with just a chip swap entail?
If the leaks play out as they suggest, the next The MacBook Air M5 would essentially offer a leap in performance and efficiency thanks to the new chip, without profound modifications to the rest of the key components: same chassis, same cooling approach and, predictably, same thermal limitations in intensive use scenarios.
For the average user in Spain or Europe, who uses the laptop mainly for browsing, working with office software, studying, watching streaming content, or occasionally editing photosThis approach may be sufficient. Daily experience with light and moderate tasks will likely improve, taking advantage of the M5's greater efficiency without requiring major internal changes.
The debate arises when considering those who, even after buying a MacBook Air, expect maintain a consistently high performance In video editing, heavy exports, development with continuous builds, or other professional workloads, combining a more powerful chip with the same passive cooling system could result in very good initial speed peaks followed by a drop in performance as the system heats up.
One of the risks is that the MacBook Air M5 will, in practice, less prepared for sustained performance than its technical specifications might suggestFrom a marketing perspective, the new processor will be the big headline, but in day-to-day use, the user experience will largely depend on how well heat is managed during long work sessions.
Therefore, although Apple's approach may make sense to the general public, some more advanced users might perceive that the Air is stagnating in terms of thermal performance, while the chips continue to improve generation after generation.
The role of the entry-level MacBook with A18 Pro and potential cannibalization
Alongside the upcoming MacBook Air M5, rumors suggest that Apple is working on a new entry-level MacBook based on the A18 Pro chipwhich is expected to arrive sometime this year. This model would be positioned as an entry-level laptop within the Mac lineup, with a strong focus on efficiency and passive cooling.
Everything indicates that this MacBook with the A18 Pro will also have a Fanless design and very measured heat managementLeveraging the experience gained with iPhone and iPad, if Apple decides to implement a more refined thermal solution, it could become an interesting alternative for users who prioritize comfort, quiet operation, and battery life over raw power.
That's where the MacBook Air M5 could find itself in a delicate position: if it keeps the same cooling system and only changes the chipSome buyers might opt ​​for the entry-level MacBook if they perceive a more stable thermal experience, even though the Air is more powerful on paper.
For the European market, where many users particularly value the relationship between price, portability and reliabilityThermal management can become a deciding factor. It's not just about preventing the equipment from getting hot in your hands, but also about ensuring that performance doesn't plummet precisely when it's needed most.
If the MacBook Air M5 ultimately arrives without changes in this area, Apple is reportedly relying almost all of the model's appeal on the new chip., leaving the cooling aspect in the background compared to what it has done in iPad Pro and iPhone 17 Pro.
Based on everything we know so far, the most likely scenario for the next MacBook Air M5 is that of a laptop that continues the current design and cooling system, gaining power thanks to the new processor but maintaining the same thermal limitations that have already been noted in M2 generationFor most everyday users, it may still be a very well-balanced, lightweight, and quiet option, but those looking for sustained performance in demanding tasks may need to look towards... other Mac ranges or wait for Apple to decide to bring to the Air the cooling improvements that it has already introduced in the iPad Pro and iPhone 17 Pro.
