Under standard operation (room temperature, 200 CFM chassis airflow), the DSL2520UZ2 runs at 55°C–75°C. It is designed to accept temperatures up to 95°C at the junction. If you feel the heatsink and it is "warm," that is normal. If it is "hot" enough to desolder itself or burn your finger instantly (exceeding 85°C on the package), you have a problem.

The D-Link DSL-2520U (specifically the Z2 hardware revision) was a widely deployed ADSL2+ Ethernet modem. As these devices age and Internet Service Providers (ISPs) retire them, users often attempt to extend their utility by repurposing them for different networks.
