Please contact MikroTik support by email:, providing supout.rif file from your devices. Also please describe your issue with details (how you are powering your device, etc.)

We`ve got similar problem witch CCR 1036.
Voltage from PSU was ~24V and reading from rOS was around ~13-14V, and what was worse, the temp on cpu was over 90 C.
When we inspect the board we found 2 broken capacitors (on foto)

After replacing them everything back to normal.
