MacBook Pro easily getting hot
My MBP Early 2015 after downgrades getting hot so easily.
Firstly, I upgraded to Monterey, seems a bit overloading for my MBP so I backed up my important data, made the Mac bootable external HDD. With Luck, I succeed downgrade to Catalina. I noticed some difference is that Catalina boot up much faster than Monterey, but just only launch Safari, CPU heat up to nearly 70 degrees but Monterey only 55 degrees average. Even just moving cursor, my Catalina is up to 65 degrees average but Monterey is just normal like 45 degrees. How could I fix this overheating problem?
