We discovered SEVERE thermal throttling with Apple’s new M2 MacBook Pro, proving that it needs a BETTER cooling system with two fans instead of one. \nWe exported 8K Canon RAW and saw temps hit 108°C, more than we’ve ever seen on a Mac, even an Intel Mac.<\/p>\n

[…]<\/p>\n

The fan was maxed out at 7200RPM the ENTIRE time, so there was nothing the MacBook Pro could do to cool itself down except for HEAVILY throttle down the M2 chip. This led to much worse performance than the M1 Pro chip, which didn’t have to max out its fans.<\/p>\n<\/blockquote>\n\n

This is concerning if it’s not a fluke.<\/p>\n

It suggests that M2 thermal load is higher than M1 by enough to warrant different cooling needs (and different buying decisions) if your workload heavily stresses the GPU.<\/p>\n

Curious about the Air. 30W seems like too much to passively cool.<\/p><\/blockquote>\n\n
