Apple continues to employ a fanless cooling design for the 13- and 15-inch MacBook Air M3 models, and while that means users will be pleased with completely silent operation, they will lose a lot of performance. The MacBook Pro M3, which has a single fan, can offer significantly improved sustained performance while promoting the same SoC, as demonstrated in a series of tests. It’s also worth mentioning that the M3 MacBook Air gets uncomfortably hot, something we hope Apple can fix in future versions.
For quick performance boosts, the MacBook Air M3 can run faster than the MacBook Pro M3
The 15-inch MacBook Air M3 was in the possession of YouTube channel Max Tech, who immediately pointed out that Apple featured the same fanless cooler design as before, but there was a chance that the power efficiency of the latest M3 meant the machine would speed up. less than those that carry the M2. Unfortunately, we were wrong in our assumption because, although the latest MacBook Air impresses in Geekbench 6’s single-core, multi-core, and Metal benchmarks, the M3’s true colors can be seen in sustained workloads, especially when the 3DMark’s Wild Life extreme stress test is run.
Somehow, the MacBook Air M3 continues to move forward, even when the highest CPU temperature reaches 114 degrees Celsius and the GPU reaches 102.9 degrees Celsius. Those high temperatures also mean that the chipset’s overall power consumption starts to drop dramatically to prevent the MacBook Air from getting any hotter, and as you can see in the comparison, it ends up being 33 percent slower than the MacBook Pro, despite that both models have the same M3 with 8-core CPU and 10-core GPU.
Another drawback of these high temperatures is that since the latest MacBook Air is made entirely of aluminum, it can conduct heat well. As those temperatures start to rise, Max Tech shows that the outside temperature of the chassis can reach between 45 and 46 degrees Celsius, which can be very uncomfortable if you have to keep the MacBook Air M3 on your laptop while running those loads of demanding work. Remember that Apple has yet to change this internal design, as the MacBook Air M2 would also reach unbearably high temperatures, losing a lot of performance compared to the MacBook Pro with the same SoC.
Fortunately, the same YouTube channel reduced those high temperatures to some extent by modifying the heatsink with $15 thermal pads. Although the thermals were exactly the same as the last time the MacBook Air M2 was stressed, this time it was able to maintain that performance for much longer periods. Those who are well versed in this area can purchase the same Amazon heating pads for a fairly low price and get more performance from your MacBook Air M3. You can also watch the Max Tech video above and see the tests performed.
