MBP 2019 Intel monitor constantly goes to sleep while CPUs and fans continue running

EtreCheckPro Report

Macbook Pro 16-inch, 2019

Processor: 2.3 GHz 8-Core Intel Core i9

Graphics: Intel UHD Graphics 630 1536MB, AMD Radeon Pro 5500M

Hello!

I have a persisting problem that only occurs when I play League of Legends.

Usually one of the cores goes above 100 degrees, and then monitor goes black.

It is not a normal sleep, since MBP is not awaken by pressing keys or moving mouse, but by shortly tapping the power button (and takes 4-5 seconds to have monitor on, and reconnect to wifi).

I am not using external monitors or keyboards, just a USB-C hub for a mouse.

I usually keep TG Pro app on, to keep track of temperatures and to keep the fans at maximum speed.

I tried running League of Legends with Metal graphics, but the problem persists.

I also started disabling the "Settings>Battery>Options...>Automatic graphic switching", in order to use the dedicated graphic card for better performance.

Please help me if anybody knows the cause or a potential solution!

MacBook Pro 16″, macOS 13.1

Based on all the bridge diagnostics, your hardware seems to be having problems. Run Diagnostics (which may not find any issues here, if they’re due to load, or transient errors) and then contact Apple Support.

I’ll assume you are not using those add-on tools to reduce fan speed. That would be bad.

Remove the Antivirus.

There are reports of some MacBook Pro models getting warmer when being charged using the left-side USB-C connections, but whether that might help or hinder, or might help sufficiently?

And this is Intel, and Intel tends to run hot. Seemingly too hot, here.

I think you will want and need a chat with Apple Support, based on all the bridge-related chatter in the EtreCheck report, and your reported symptoms, and your reported history of efforts seeking to mitigate.

Thank you for the response!

I have ran the diagnostics multiple times but they always tell me the macbook has no problems.

I am using the add-ons to always maximize the fan speed, hoping it will reduce the temperature even by a little.

The log tells me the only antivirus program left is Apple’s, as I previously attempted to uninstall every other.

Another notable point is that the problem does not seem to occur when I am not using the charger. When I am using the charger, my “Optimized charging” is turned on. Do you think that could be the cause?
