Is there any M1 Max 14 inch user that having overheating problem?

Recently, I’ve bought 14" M1 Max. But I am thinking buying 14" (smaller cooler), was a mistake. Because it is much sooner overheating if I do some cpu & gpu intensive tasks and performance drops. For example, If I run game, temps quickly bumps to 90 degrees. Is there anyone having this issues or my machine is faulty?

As you already said, smaller chassis means smaller cooling.
