Review on Enhanced Cooling Case for Raspberry Pi 4 Model B – Geekworm Armor Case with Dual Fan, Aluminum Alloy Construction for Effective Passive Cooling by Mike Cox

Nice case, good fit but as Mr Thomas said above the thermal pads on the frame and the USB controller don't touch the case which actually acts as a heatsink. Well built and easy to assemble with the included hardware, and the thermal pad makes contact with the CPU but not other chips. It would be nice to use a thicker thermal pad or two included in the box. 42s idle. EDIT: Adding 2 stars for the communication this company provides. Within a day of posting my review the guys contacted me and said they had a fix for the thermal pad issue and it might have been a bad batch. If they can fix the problem of the heatsink contacting all the chips, then it's a 5 star product. Already 5 stars for communication with customers.
