A cooling effect of 12.7℃ compared to commercially available Raspberry Pi plastic cases! A high-performance product with excellent cost performance starting at 2,190 yen.

This is a heat-dissipating heatsink case for the Raspberry Pi Model 4B. The top cover has a heatsink shape that efficiently dissipates heat, and it is made of aluminum die-cast, which offers excellent strength. Despite being a high-functionality case, it is a cost-effective product priced between ¥2,190 and ¥2,340. Inside the cover, you can choose between a type with thermal conduction protrusions (H type) and one without (N type), with the protrusion type including a thermal conduction sheet. Please attach the thermal conduction sheet to the CPU and RAM, which generate a lot of heat. You can choose between a desktop type and a wall-mounted flange type. The flange type has a VESA standard mounting pitch (75×75mm/100×100mm), allowing it to be mounted on the back of a PC display, among other places.
