Introduction

CM4 Cooler is a heatsink specially designed for Raspberry Pi Compute Module 4, which ensures Compute Module 4 works reliably.
CM4 Cooler is a heatsink specially designed for Raspberry Pi Compute Module 4.
Due to the higher performance of Compute Module 4, its power consumption gets higher than Compute
Module 3+. The temperature of the CPU is close to the temperature limit-85°C when the environment temperature
is 25°C and the CPU is fully loaded. Besides that, PMU and Wireless Module (CM4 with wireless function) are also very hot. Three thermal-conductive pads are attached to the back of the CM4 Cooler to ensure CM4 Cooler is also very hot. Three thermal-conductive pads are attached to the back of the CM4 Cooler to ensure CM4 Cooler is closely attached to the CPU, Wireless Module and PMU on the Compute Module 4. The heat of these three components is dissipated by CM4 Cooler through the three thermal-conductive pads.

There are four nylon washers packed with CM4 Cooler, 1.5mm height & 3mm height optional for 1.5mm and 3mm height 100pin board to board connector. They are used to support Compute Module 4 and avoid damage to the board-to-board connector or deformation of Compute Module 4 when the screws are used to fix the CM4 Cooler on the Compute Module 4. There CM4 Cooler on the Compute Module 4. There’s no need to solder the stand-off that secures the Compute Module 4 on the PCB when customers design their own baseboard, which saves money.

CM4 Cooler can reduce the temperature of Compute Module 4 by a maximal 20°C when the room
temperature is 25°C and CPU & DDR memory are fully loaded. The actual heat dissipation performance will be variable according to the temperature difference between the environment and Compute Module 4. Please check the CM4 Cooler cooling performance testing report for more details.
CM4 Cooler is available in black and silver. It also supports the full series of Compute Module 4 including the Wireless version.
