M2 MacBook Air Thermal Mod How-to

The second folks began to get their palms on the M2 MacBook Air, overheating and thermal throttling had been massive subjects 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 may be augmented with a easy $13 change that may enhance the MacBook’s efficiency throughout heavy and sustained workloads.

The precise modification itself is straightforward, and it simply includes placing a low-cost thermal pad contained in the laptop computer. This offers thermal conduction between the M2 chip and the metallic backside of the laptop computer, preserving the chip cooler for longer and permitting it to carry out higher. However whereas the mod itself is easy, it is best to take into account the related dangers earlier than doing so your self.

Including the thermal pad

Really modifying the MacBook Air to get the enhancements is pretty straight ahead and simply includes 4 screws, however earlier than you try this learn the protection part. Together with your system turned off and unplugged, on the underside of the M2 MacBook Air, there are 4 P5 Pentalove screws holding on the underside of the chassis. A suitable screwdriver may be picked up pretty cheaply or as a part of a bigger electronics restore package. With all of the screws out, you’ll need to carry up the panel on the entrance, left, and proper sides to disconnect inside 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 first rate 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 more difficult to reattach the underside panel. Minimize the thermal pad to measurement and apply it, fastidiously, beneath the ribbon cable.

To reattach the underside panel, you’ll need to slip the 4 hooks towards the rear of the chassis into place. This takes care and a little bit of drive, so watch out and make 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 perimeters to reattach the clips earlier than changing the 4 screws.

As you go to place the screws again in, make observe 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.

*With the second run, the unmodified M2 Air had a bit extra time to chill off, however the future runs had been all began instantly after the earlier one completed.

After operating these assessments and seeing the enhancements, I needed to see if a 1.5mm thermal pad would supply 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 virtually 500 factors greater than the M2 Air modified with the 1mm thermal pad.

Potential points

Whereas many people all the time need to get probably the most out of our {hardware}, there are some points that may end result from the mod.

It would result in the underside of the laptop computer getting hotter than is advisable. This will make it uncomfortable to make use of in your lap when operating 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 harm you trigger by taking it aside and making modifications will doubtless not be lined.

There may be additionally the danger of fireside must you harm the battery. Not one of the set up of the thermal pad requires you to mess about with the battery, however as you might have the laptop computer open, make sure to not apply extreme stress to or puncture the battery cells. This might trigger a lithium hearth – which is extraordinarily troublesome 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 aware of, correct battery security procedures.

I’ve additionally seen a number of folks anxious about degradation to the SSD and battery that might end result from the additional warmth switch of the thermal mod. In my testing, the pc’s SSD and battery sensors didn’t appear to point out extreme warmth because of the modification – however that’s to not say it couldn’t be the case. Apple doubtless throttles the chip to gradual it down and cut back warmth if different parts – not simply the CPU – are getting too scorching. So whereas it’s essential to concentrate on this potential, I don’t suppose it is going to really grow to be an issue.

Ought to YOU mod your MacBook Air?


For 95% of individuals, doing this may be a whole waste. Should you’re simply doing basic internet searching, doc enhancing, and media consumption, you received’t want or use that additional energy. The opposite 5%? Nicely, most of these folks 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.

Should you actually need to experiment and mess around with your personal {hardware} to get the very best efficiency from it, by all means, accomplish that at your personal danger. I plan to maintain the thermal pads in my daily-driver M2 Air, however simply take into account it fastidiously (and don’t blame me in the event you break one thing whereas opening it up).
