The search term "dsl2520uz2 firmware hot" is a cry for help from a storage administrator watching a server crash in real-time. The takeaway is simple: Firmware controls thermals. A cool, stable expander indicates healthy, validated code. A burning-hot chip indicates either a failed flash or an incompatible binary.
Always use OEM-signed firmware. Always increase fan speed before updating. And never, ever trust a firmware file from a non-vendor source.
If you have followed this guide and your DSL2520UZ2 is still scalding hot after two reboot cycles, the chip is likely physically damaged. Replace the backplane or expander card immediately to protect your data drives.

Your server's fan curve is likely set to "silent" or "balanced." During a firmware update, override the fan profile to 100%. The flash process takes 60-120 seconds of high CPU usage on the expander. Without 400+ LFM of airflow, you will overheat.
The steps to update the firmware might slightly vary depending on the manufacturer. Here's a general guide:
