Geekworm 8PCS Brass Heatsink CPU Cooler for Raspberry Pi 5/4B/3B+/3B

The Geekworm Heatsink CPU Cooler for Raspberry Pi has received overwhelmingly positive reviews from customers. Many users have praised the copper heatsinks for their excellent heat conductivity and effective heat dissipation. Customers have found these heatsinks easy to install and correctly sized for their devices. They have reported that the heatsinks do a great job of removing heat and keeping temperatures under control. One customer mentioned using these heatsinks on an ESP32, where they observed that the copper heatsink effectively conducted heat from the IC and dissipated it into the air. The customer also noted that the adhesive seemed to hold up well initially but was unsure about its long-term performance. Another user appreciated the modifiability of these heatsinks, mentioning that they were able to modify them slightly to fit their specific case. The customer found that the heatsinks worked perfectly for their needs. Some customers have used these heatsinks for SSDs that lacked their own cooling or were unable to be covered by a motherboard heatsink. They found that the heatsinks stuck well, had a low profile design, and effectively kept temperatures under control alongside proper airflow. One user mentioned using these heatsinks on an Orange Pi 4 LTS 4GB and found that they provided adequate cooling even without a fan. Overall, customers were satisfied with the quality of these heatsinks and appreciated that they were made of real copper. However, one customer noted that while these copper heatsinks were slightly better than common aluminum heatsinks, the difference was only significant if the device was being heavily overclocked. Otherwise, regular aluminum heatsinks and a small fan would suffice. Overall, the Geekworm Heatsink CPU Cooler for Raspberry Pi has received positive reviews for its effective heat conductivity, easy installation, and correct sizing for various devices. Customers have found them to be of good quality and praise their ability to keep temperatures under control.
