Lebedev "Mighty Semchan" Semyon A recurring issue with Nvidia's latest GPUs—the overheating and potential melting of their 16-pin power connectors—has prompted innovative solutions from third-party manufacturers. Testing has shown that these connectors can reach temperatures exceeding 150°C, prompting companies like Cablemod and Ezdiy-fab to develop cooling adapters equipped with specialized heatsinks.

Similarly, Cablemod’s solution utilizes a copper PCB combined with an aluminum heatsink for optimal performance. While the exact temperature reduction remains unconfirmed, these adapters aim to significantly lower connector temperatures during intensive use.

Cablemod highlights its adapter’s unique design, featuring an aluminum heatsink specifically engineered to dissipate excess heat from the problematic 12VHPWR or 12V2x6 connectors. Additionally, the accessory includes an improved thermal interface for better heat transfer and a shape designed to prevent cable bending, reducing the risk of damage.
