Due to the CM4's higher performance compared to previous generations, it runs significantly hotter -- at 25°C ambient with a fully loaded CPU, temperatures reach around 80°C, close to the 85°C thermal limit. The CM4 Cooler addresses this with three thermal pads that simultaneously conduct heat away from the CM4's CPU, wireless module, and power management unit (PMU), reducing temperatures by up to 20°C under full CPU and DDR memory load. The cooler can keep the CM4 running at full CPU load in ambient temperatures up to 50°C. Available in Black and Silver finishes, it supports the full range of CM4 variants including wireless models.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible with:\u003c\/strong\u003e Raspberry Pi Compute Module 4 (CM4) -- all variants including wireless\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3 Thermal Pads:\u003c\/strong\u003e Simultaneously cools the CM4 CPU, Wi-Fi\/wireless module, and PMU\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCooling Performance:\u003c\/strong\u003e Reduces CM4 temperature by up to 20°C at 25°C ambient under full CPU and DDR load;
