Hi,

I installed Intel Power Gadget because my MacBook Pro (13-inch, 2019, 2.8ghz i7, 16gb ram) was getting extremely hot just watching youtube on chrome. I had to use a desk fan just to lower the temperature on the palm pad.

I installed IPG and it asked me to type in "sudo touch /Library/Extensions" in terminal.

I ran three youtube videos on dual external monitors(27" 2560 pixel monitor, and 1080p monitor) and on the macbook screen. I was also processing 100 24 megapixel raw files in Capture One 12.

IPG showed temperature between 80 to 90 degrees. It is now 70-80 degrees while watching a youtube video and the palm rest is incredibly hot.

Why does MBP get so hot while on idle? I regularly reset pram and smc. Is it the i7 chip that cannot idle at low temp? I have a desktop fan blowing and the palm rest on the right is very hot. The laptop fan has not turned on once.

My main problem is that I cannot use this on my lap because it gets too hot. I have four little furniture moving stickers on the bottom of the laptop for airflow on a table and this helps with the desk fan I use to cool the laptop.

Thanks.

According to the screenshot you have posted your CPU is very far from idling. Its average power draw is essentially at its sustained power draw limit, the CPU is running a high clock and CPU utilisation is very high. High temperatures are quite normal under these circumstances. No idea what you are doing to push your machine this hard, but I am doubtful that just watching YouTube would do it.

This is not idling, this is literally 60% utilisation.

my mini right now on two screens and Logic Pro X huge project open (but not playing).
this isn't even idling, but its 5x less utilisation.

Anyway, my 2018 i5 2,3GHz is not running hot. It's one of the coolest laptops i've used

I bought the 2019 13 inch base spec two months ago. It got so hot and uncomfortable that I bought an infrared thermometer to make sure I wasn't imagining things. I compared it to my old 2015 13 inch and it was between 5 - 10 degrees celcius hotter on every measurement.

Not only that - but unless I used my old power plug - as they don't include one with the new one - it was transferring considerable amounts of electricity through my body - as measured by a vu meter.

The last straw for me with Apple - they are so keen to save money they don't mind subjecting their users to 'electric jizz' - which i was first alerted to when it felt like parts of the machine were vibrating!

Did you take it to Apple to get it fixed? The max voltage on these devices (from power supply) are 20V which you should not be able to feel. If you feel anything, the high voltage for display is leaking and machine needs to be fixed.
They may be hotter due to design, do not know, I have 2017 which is not hot. But they should not zap users. Unless it is static electricity which is not related to power supply and device itself, just to environment which charges it somehow.

It's almost certainly because of all the displays you're driving. Just sitting on a bare empty desktop, my 13" 2019 MBP got CRAZY hot while hooked up to a 5K ultrafine display. Your Macbook display has about 3.7 million pixels it's refreshing 60 times a second. Combined with your other two monitors, it's driving a total of 8.2 million pixels. Your iGPU is working overtime and that's heating up your computer.

I confirmed this theory by purchasing an eGPU and hooking that up to the 5K ultrafine. My 13" MBP was cool as a cucumber after that, even running 3D applications like Blender/Unity.

You're pushing your laptop pretty decently (with the CPU peaking at 80%), those temps are perfectly normal. You have 4 cores in a thin and tiny enclosure, its going to get hot.
