Geekworm 4mm Thickness Brass Copper Heatsink H402 for Raspberry Pi 4

The Geekworm 4mm Thickness Copper Heatsink H402 for Raspberry Pi 4 has received a mixed reception among users, with opinions split on its thermal performance and material authenticity. Many reviewers praised the heatsink’s ability to reduce temperatures significantly for their Raspberry Pi 4 setups, with reports of cooling efficiency leading to lower operating temperatures, even during intensive tasks like gaming or running software applications. One user noted a drop from 65°C to 55°C, while another reported an impressive decrease from 52°C down to 45°C, which they preferred for long-term use. The build quality of the heatsink was generally appreciated, with comments highlighting its fit and finish. Additionally, users welcomed the inclusion of extra silicone pads and mounting hardware, enabling flexible installation options. However, there are serious concerns regarding the product's claimed material composition. Some customers vehemently criticized the heatsink, arguing that it is made of Zamak (a cheaper zinc alloy) rather than pure copper, which they claim significantly undermines its thermal conductivity. This led to claims that the heatsink does not perform as well as expected when compared to other materials like aluminum or genuine copper. In summary, while the Geekworm heatsink has been effective at cooling for some users, the integrity of its material claims and inConsistent performance results have left a divide in customer satisfaction. **
