Review on 🖥️ GeekPi Acrylic Case with Fan and Power Supply for Raspberry Pi 4, Complete Kit with 4 Aluminum Heatsinks - Ideal for Raspberry Pi 4B 8GB/4GB/2GB (Board Excluded) by Jeff Kersey

Instructions were included with the packaging. don't follow them Instead, use the video here as part of the product information. The demo and order they used in the video is much easier than the suggested instructions that came with the box. It also helps a lot if you have a picture for reference. I liked this case so much that I bought two of them! In them I run max overclocked 2.147Ghz units, force turbo, surge 6 on all 4 cores at 100% 24/7 in Florida with terrible AC. Not ONCE have my devices experienced thermal throttling. I assure you that you will not be able to generate enough heat from this unit to overwhelm the cooling provided by this case, fan and heatsinks.
