My 2019 MacBook Pro gets HOT and the fan runs 12+ hours a day!

I purchased a macbook pro 13 inch. From day one, it operated very hot while not performing anything really taxing on the cpu.
I ended up returning the macbook pro before the end of the 14 day period. The assistant at the genius bar also noted that my macbook pro was operating very hot. He turned it on & within a minute he could feel the heat from the CPU. He suggested a full refund & that I should order a new (special order unit) from Apple.
I'm thinking that maybe I should wait & see if Apple fixes the issues with the keyboard & the overheating problem...

What about a $2,500 laptop? Or $3,000? How much DO we need to spend to bend the laws of physics?

6 MacBook 12", 1 for the live info on graphs and the other 5 to each take care of 1 live stream station.

NONE of them will ever make a single sound.

Total cost? Probably $7000 or more, but there you go, law of physics bent.

I just started using turbo boost switcher, and it’s doing a lot to help keep heat and fan noise under control.

It is a little frustrating having to cripple the CPU to bring heat under control when there’s no way to cripple the GPU instead. But on the positive side disabling turbo boost isn’t a huge performance hit in real life use, it’s easy to turn it back on if needed, and it really does help keep the temperatures and fan speeds down, as well as increasing battery life. Pretty sure I’m going to drop the $10 for the Pro version as it has options to automatically shut off turbo boost in certain situations like power cord unplugged or having certain apps open.


Again I’m not saying I’m happy about having to cripple the cpu to get heat under control. Why doesn’t somebody develop an app to control how much power the GPU is able to use...

Probably because apple has locked down the system, system manufacturers can choose between different chip types that permit over clocking (or under clocking I guess). Apple doesn't let you do that AFAIK

The issue is the small enclosure and how much heat the chips are generating, passive cooling only works so well and that's why the fans need to kick in, especially as the cpu or gpu work harder
