I'm from California... What is this "cold" you speak of?

Alternatively, you could try compiling an Xcode project. That should do the trick as well.

Won't work on M processors, (un)fortunately.

I recently installed an app to manually activate the fans on my MacBook Pro M1 Pro as I've never been able to trigger them over the past 4+ years. Just to check whether the fans even work (they do).

I left my Mac Studio running at 100% CPU on all cores for 14 hours, and the case ended up noticeably warm to the touch. It is possible!

Earlier quoted context omitted.

Honestly m1 was very cool no matter what workload you threw at it but at this point m4 max does get pretty hot even with just web browsing.

I've definitely had my m1 air get uncomfortably hot to touch - particularly right above the keyboard. (While doing developery things)

Can't say I've ever thought of a word like "developery", but now that I've seen it I like it a lot :-)

Try increasing to 10 cores. Works on my m3 pro.

I get them going full blast in 2 minutes from cities skylines.

Needs 2019 in title, this is Intel MacBooks not Apple Silicon.

How does the Neo getting to 100°C make it crap? By that logic, aren't all older Intel/x86 chips crap? If anything, I find it impressive that a small laptop CPU can do 100°C without a problem...my i7-7700T M710qs hit 75°C and throttle within a minute if I use a tool like y-cruncher or stress-ng. To be fair, totally different purpose.

I think my last Macbook was Wisconsin-locale instead of California. Closing the lid and putting it to sleep actually caused it to heat up (until the battery died).
