The Reason the New MacBook Air Has No Fans

MacBooks have always been characterized by their fans that were activated at full power simply by opening an application. From Apple they have wanted to end this problem and that is why one of the characteristics of the MacBook Air with M1 is the absence of fans. In this article we will tell you why this Mac can not have an active ventilation system.

The M1 chip advantage

The 2020 MacBook Airs are mainly characterized by including Apple’s first proprietary chip, the M1. This one has numerous advantages over Intel processors. For example, the CPU, GPU and Neural Engine are grouped in the same space. Sending information between all these components of the system is much more efficient by not having to travel long distances, increasing response performance. The fact that this is a processor designed by Apple itself, means that it has been created to fully coexist with the operating system. This is really important to improve performance by copying something that you already have in the iPhone where the processor and the operating system go hand in hand, making it not necessary to have a lot of RAM.

MacBook Air Has No Fans

All of these performance benefits from chip design also apply to the processor. Apple has managed to create an M1 chip that stands out for its energy efficiency. By improving efficiency, all the energy supplied to the chip is not wasted. All the energy is used by the chip to carry out the different tasks that are requested, gaining in performance, preventing it from being released in the form of heat.

Thanks to this fact the MacBook Air can afford not to install any type of fan. Obviously there is no perfect efficiency and a system must always be created to dissipate heat. In this computer Apple has designed an aluminum diffuser that dissipates the heat generated by the system by moving it towards the ventilation outlets that are on the sides. In this way, it is not required to have a fan that moves the heat since through this diffusion system it will move to the outside without the need for moving air.

How does not having fans impact?

Unfortunately, Apple laptops have always been known for activating their fans too quickly. This has a clearly negative part that results in constant noise when doing a simple task on the computer. By removing the fan, this constant noise is drastically reduced. But the big question that can be raised now is whether the absence of the fan is noticeable when it comes to performance. The reality is that no, since while the comfort is gained, the performance remains at very optimal values. The passive heat transport system works very efficiently and all this thanks to the M1 chip.

Review MacBook Air M1 Apple Silicon

If we put ourselves in the situation of Intel processors this is something totally unthinkable in a computer with a size like the MacBook Air. In these cases it should be remembered that running a simple program could cause a significant increase in the internal temperature of the computer. This is where we clearly see that the M1 chip and its energy efficiency is much higher than that offered by Intel processors.
