I am using the Cooler master one, e.g. article here tomshardware.com/…/cooler-master-pi-case-40-revie…

That one however makes the GPIO pretty unusable, so yours seems better.

I am using Jellyfin and Immich on mine mostly, it is rare that the PI gets hotter than 50-55°C. Don’t know if that’s good since I have no point of comparison. It took a long time at 100% load which got the temperature up to 70°C, but that was just once when I made the mistake giving Photoprism my whole photo library at once.
