overheating issues

i have a one plus 9 5g with a snapdragon 888 chip and 8Gb ram,,, I'm a very heavy gamer, the phone overheats like crazy ,i also have a redmi k20 pro with much lower specs than the one plus 9 and somehow it doenst compromise perfomance like the one plus...im thinking of getting the Redmi k60 (12GB RAM, 256GB STORAGE AND SNAPDRAGON 8+ GEN 1) ANY ADVICE DO YOU THINK I WILL GET BETTER PERFOMANCE WITHOUT THE OVERHEATING ISSUES??
