Is that this "warmth dissipation cellphone case" good and actually dissipates warmth than the common cellphone case?

Context: I’ve been enjoying video games on my s20 FE 5g with Galileo G8+ and haven't use a case primarily due to my case being too thicc for the rubber of G8+ that holds the cellphone in place.

Is it actually dissipating warmth particularly when there's airflow on the cellphone? I'm planning to purchase one however hesitant as a result of I don't actually need it as I nonetheless have a case and doesn't have a lot cash to carelessly spend on one thing. Thanks upfront!
