Headsets don't seem built for airflow. Index has fan mods and there are a few different Quest 2 third party fan addons. Most either only pull air out or don't have enough airflow to do more than just defogging. One does have decent airflow in but apparently it's very noisy. As nice as a smaller headset will be I don't see the heat issues getting better when we're cramming OLED/uOLED, pancake lenses and compute components into such a small space.
Apple actually have a patent for venting panel heat out of the sides of a HMD so hopefully other companies are working on solutions too.

Pic related is the opposite, it suffocates you for immersion.
