One of the major differences between the MacBook Air and the MacBook Pro is that the Air lacks cooling fan . That means the Air will slow down its execution if the task at hand causes the computer to generate excessive heating system . That ’s always been the case with the Airs , but apparently , it ’s jumped to a new extremum with the M3 MacBook Air .
Max Techhas done some extensive benchmarking with the M3 MacBook Air and discovered that when using theM3 Air in grapple mode with two outside displays , one of the laptop ’s major new features , the laptop computer throttles so much that operation could be cut in half . Max Tech was able-bodied to do this by running the3D Mark Wildlife Extremebenchmark for 20 minutes . After the sixth moment , the performance starts to duck and it persist in to do so until about 50 pct of the performance is lost .
We ’ve mentioned ( and experienced ) the MacBook Air throttling with past models , and even saw some of it while test the new M3 MacBook Air with the laptop computer open . The clamshell mode ( where the Air is closed while connect to external displays ) shows a more drastic cliff than we ’ve look with past Air models due to the laptop ’s lack of a fan .
The argument can be made that the billet that make the fall is an outlier , but it ’s not–3DMark Wild Life Extreme is a 3D graphics exam that perform tasks commonly used in high - oddment games , and Apple touts the Air as a adequate to play laptop . Also , the throttling is n’t just with this one benchmark test . Max Tech see a similar drop cloth inCinebench 2024and with anAdobe Lightroom Classicimage import .
How to maintain M3 MacBook Air performance in clamshell mode
Max Tech tried a few dissimilar things to prevent the M3 MacBook Air from throttling down . First , they used aSvalt Cooling Block , which is a laptop computer stand that also doubles as a rut sump , imbibe away heat that ’s dissipating through the bottom of the pillowcase . Then they used the Svalt Cooling Block with aSvalt cool off Fan Fx . Both method acting decoct the amount of throttling , with the Block / Fan setup being good than with just the Block .
Lastly , they cracked the Air pillow slip , installed thermal pad , and placed the Air on the Block with a Fan . This frame-up was the most successful , showing little to no throttling or public presentation loss . In fact , in some tests , the Air slightly outperformed theM3 MacBook Pro .
Using the Svalt Cooling Block with the cool off Fan Fx is a unsubdivided method acting to address the problem , but it ’s a pricey one – the Block is $ 279 and the Fan is $ 49 . add together that to the cost of the$1,699 15 - inch MacBook Airused in Max tech ’s testing , and you ’re paying $ 2,023 , which is $ 24 more than the $ 1,999 14 - inch M3 MacBook Pro that willsoon be updated to confirm two displays in grapple modelike the Air . garish stands with cool down fans are uncommitted , but it ’s not love how good they are for this function . add thermal pads is also relatively well-off , but not everyone feels well-off with collapse subject a MacBook to get to the inner working .
Why does the MacBook Air have no fans ? So Apple can make it as thin and light as possible . However , the technology does exist where Apple could put fans in the Air without making the laptop heavy . A few months ago , I saw a demonstration of ahacked MacBook Air outfitted with Frore ’s AirJet , which is what Frore calls a “ self-colored - state active cooling chip . ” They ’re fans that are a little openhanded than the size of it of an SD Card . The AirJet disembowel the heat energy out from the Air ’s CPU , which allowed it to maintain carrying into action . AirJet is n’t a product consumer can buy , but it could be an alternative down the line as processors get more powerful and introductory indigence get more demanding .
Apple has not comment on Max Tech determination , but Apple has always positioned the MacBook Air as a general consumer laptop that can do the occasional heavy - duty undertaking usually done with a pro - level app . If you obtain yourself doing loading - expectant work consistently , a MacBook Pro ( which has cooling fans ) is more appropriate .
