Non-story. You trade performance for a fan less design and portability, and even then the burst performance (which is what people consuming content like websites) is great for quite a long burst. I’m usually a defender of Apple to be perfectly honest, but the trade off here definitely feels a lot more fair to to user. They could downclock the CPU, fix the sustained load performance by having it less than the current burst and never thermal throttle. But that’s a worse experience for no actual user benefit. And adding thermal pads turns the thig into a very uncomfortable device that potentially causes infertility.

all of the above is correct, and you also trade performance for not being excessively hot and roasting the battery. there's a reason apple did not thermally bridge the cpu to the chassis as in the not-recommended mod mentioned in the article, because it would make the battery less safe and greatly decrease its lifespan.

  I don't think that is the main problem. The main problem is that it is illegal for laptops and similar devices to become over 45-ish degrees C at point of contact (lap). I can't remember if it was in the USA, Canada, or EU.

    I think the major safety standard is set by the IEC (which is International); the exact safety standard is here behind a paywall: https://webstore.iec.ch/publication/494 https://webstore.iec.ch/publication/494 It's heavily referenced (with embedded snippets) in this report: https://www.researchgate.net/publication/295857251_Ouch_Hot_Laptop https://www.researchgate.net/publication/295857251_Ouch_Hot_... tl;dr: 40-50c for a device with metallic chassis. 60-70c for device with plastic chassis (I can't be sure what the precise recommendation is as I see 40c referenced but 50c also referenced in other parts, depending on contact period etc;)
