The Vilros "WAVE" Raspberry Pi 5 Compatible Aluminum Alloy Active + Passive Cooling Case is a Case designed to passively provide massive cooling to a Raspberry Pi 5 board and also provide active cooling for when the passive cooling is not enough. Not only does the case contact the onboard chip to pull heat away from the board, it also features a wave/fin design to dissipate the heat from the case. If the board still gets too hot even with its heatsinking capacity the Built-in PWM fan with fan connector will automatically power on/off as needed as well as increase/decrease RPM based on the board temp. Optional accessories including a wall mount as well as a GPIO cable adapter are available and sold separately. Note: This case contacts the main chip only as our testing has found that when using in this case it is not necessary to add additional heatsinks on the other chips. Customers who want to add additional heatsinks can add the Vilros 6 Piece Heatsink Set for Raspberry Pi 5 and add heatsinks to the 5 remaining chips.
