Loud fans & less power: MacBooks can be loaded incorrectly

The MacBook Pro can be charged on both sides via the USB-C ports. Reports suggest that the choice of page can affect the performance of Apple notebooks. It is therefore better to plug in the charging cable on the right.
With the MacBook Pro, the choice of port seems to make a difference
Apple's official recommendation is clear: the company writes in a support document that MacBook Pro models can be loaded on both sides. As Techspot now writes in its report, there have been user reports for months that contradict this reference. As a user of the StackExchange platform writes, he investigated the cause of an unusually high CPU load and the resulting heat development by the process "kernel_task" and found unusual results.
Apple itself states that the corresponding process is responsible, among other things, for controlling the fan control in connection with the CPU temperature, and the access options of programs to the performance of the processor are also determined here. The curious finding during a detailed examination: If the charging cable is connected together with other devices on the left, the temperature and system load increase significantly. A closer look at the values of the sensors on the Thunderbolt connections confirms this observation, according to the user concerned.
Just load on the right
The solution to the problem is similarly curious: If only the right side is used for loading and the left side is used exclusively for peripherals, the heat problem does not occur and the kernel process is also ended. As a further investigation by another user shows, the measurable differences of up to 15 degrees are very clear. Currently, two models seem to be affected by the problem: the 15-inch MacBook Pro 2017 and the 16-inch MacBook Pro 2019. Apple has not confirmed the problems so far - but the company is happy to take a lot of time to make such statements. Apple, teardown, MacBook Pro, Ifixit, Apple MacBook ProiFixit
