Whilst the GPU is is at max freq., the CPU is throttled down from usual frequencies, but when loading levels and stuff, the CPU will boost, and then the computer fan becomes louder than the ceiling fan and then I quit because Macs are expensive and I don't think like I am doing the right thing.

The maximum junction temperature for the processor, as stated by Intel is 100✬. I live in Australia, so room temperatures will often exceed 25✬, but will never be more than 30✬ whilst I'm in the room because the A/C will go on. I place a pen on the side of the laptop so that there is more airflow (1 mm at the lowest to 13 mm at the highest). Thus, running max GPU clock running max graphics settings is fun, however within a two minutes the package temperature sits between 90✬ and 100✬ and stays there, with the fan revving like crazy. I was playing certain games, but CS:GO, is especially stuffed up and doesn't allow me to change settings, so the resolution is too long vertically, and I can't turn down the graphics settings. I have found that the graphics card produces a lot of heat. I regularly use Intel Power Gadget to keep an eye on temperatures and frequencies. Graphics card is Intel® Iris® Plus Graphics 655. My processor is an Intel® Core™ i5-8279U. I have a MacBook Pro 13.3' 2019 (4 thunderbolt ports), an I have been concerned about overheating for a while.
