The second individuals began to get their fingers on the M2 MacBook Air, overheating and thermal throttling have been large matters of debate. Whereas the efficiency of the M2 Air is greater than sufficient for most individuals utilizing the laptop computer for basic work, the present cooling system could be augmented with a easy $13 change that can enhance the MacBook’s efficiency throughout heavy and sustained workloads.
The precise modification itself is simple, and it simply entails placing a low cost thermal pad contained in the laptop computer. This offers thermal conduction between the M2 chip and the steel backside of the laptop computer, maintaining the chip cooler for longer and permitting it to carry out higher. However whereas the mod itself is straightforward, you need to think about the related dangers earlier than doing so your self.

Including the thermal pad
Truly modifying the MacBook Air to get the enhancements is pretty straight ahead and simply entails 4 screws, however earlier than you try this learn the protection part. Along with your system turned off and unplugged, on the underside of the M2 MacBook Air, there are 4 P5 Pentalobe screws holding on the underside of the chassis. A appropriate screwdriver could be picked up pretty cheaply or as a part of a bigger electronics restore package. With all of the screws out, you’ll wish to carry up the panel on the entrance, left, and proper sides to disconnect inner clips, after which pull the panel towards the entrance to take away it from the hooks on the rear of the system.
I personally used a 1mm thick thermal pad throughout my testing and noticed respectable enhancements in efficiency, however others have used a 1.5mm thermal pad to get even higher thermal switch; that thicker thermal pad makes it a bit tougher to reattach the underside panel. Reduce the thermal pad to measurement and apply it, fastidiously, beneath the ribbon cable.
To reattach the underside panel, you will have to slip the 4 hooks towards the rear of the chassis into place. This takes care and a little bit of power, so watch out and be sure that all 4 hooks go beneath the screw heads. As soon as the underside panel is slid again into place, push down alongside the edges to reattach the clips earlier than changing the 4 screws.
As you go to place the screws again in, make word of the threading. The 2 screws with shorter threading go behind the laptop computer nearer the hinge, whereas the screws with extra thread go close to the entrance of the laptop computer.
Efficiency enhancements
Even with the comparatively low-quality and thinner thermal pads I used, the M2 MacBook Air with the thermal pads carried out dramatically higher than the M2 MacBook Air with out thermal pads. Whereas each laptops reached excessive sufficient temperatures to thermal throttle, the modified M2 Air nonetheless carried out considerably higher whereas throttling than the unmodified M2 Air.
After working these assessments and seeing the enhancements, I wished to see if a 1.5mm thermal pad would offer even higher contact and efficiency. Whereas it took a bit extra effort to reattach the underside panel, with that thicker thermal pad the M2 MacBook Air obtained an preliminary Cinebench rating of 8535. That’s 930 factors higher than an unmodded M2 MacBook Air and nearly 500 factors larger than the M2 Air modified with the 1mm thermal pad.
Potential points
Whereas many people at all times wish to get essentially the most out of our {hardware}, there are some points that may outcome from the mod.
It’ll result in the underside of the laptop computer getting hotter than is really helpful. This may make it uncomfortable to make use of in your lap when working at full energy – there’s a purpose Apple didn’t design the M2 MacBook Air to do that. Moreover, whereas simply taking aside an digital system like this may occasionally not void your guarantee, any injury you trigger by taking it aside and making adjustments will possible not be coated.
There’s additionally the chance of fireplace must you injury the battery. Not one of the set up of the thermal pad requires you to mess about with the battery, however as you’ve gotten the laptop computer open, be certain to not apply extreme strain to or puncture the battery cells. This might trigger a lithium hearth – which is extraordinarily tough to place out. As Apple explains of their personal restore manuals, within the occasion of a battery hearth, you want a buck of sand close by to smother it. Learn up on, and be accustomed to, correct battery security procedures.
I’ve additionally seen a number of individuals fearful about degradation to the SSD and battery that might outcome from the additional warmth switch of the thermal mod. In my testing, the pc’s SSD and battery sensors didn’t appear to indicate extreme warmth because of the modification – however that’s to not say it couldn’t be the case. Apple possible throttles the chip to sluggish it down and cut back warmth if different parts – not simply the CPU – are getting too sizzling. So whereas it’s essential to pay attention to this potential, I don’t suppose it would actually turn into an issue.
Ought to YOU mod your MacBook Air?
No.
For 95% of individuals, doing this may be an entire waste. For those who’re simply doing basic net searching, doc enhancing, and media consumption, you gained’t want or use that further energy. The opposite 5%? Nicely, most of these individuals ought to in all probability go along with a extra highly effective laptop computer or desktop with energetic cooling as an alternative – one thing just like the 14-inch M1 Professional MacBook Professional.
For those who actually wish to experiment and mess around with your individual {hardware} to get the perfect efficiency from it, by all means, achieve this at your individual threat. I plan to maintain the thermal pads in my daily-driver M2 Air, however simply think about it fastidiously (and don’t blame me if you happen to break one thing whereas opening it up).
