Review on 🔥 Alphacool Copper Heatsinks 14mm 10 Pack for Enhanced Cooling Performance by Jay Arnold

Used on Raspberry Pi 4 with thermal tape (sold separately). Before installing it on the Pi, I folded the fins outward to form almost a semi-circle to allow more airflow between the fins and passively release more heat into the air. I didn't do any before and after temperature measurements, but I will say that the thermal capacity of the copper keeps the CPU temperature stable and helps my RBP4 not reset its CPU. At room temperature around 21°C, the processor displays up to 65-68°C under load with passive cooling. If I put a fan on it, I'm sure the temperature will be very close to room temperature.
