Good afternoon! I changed the power source, nothing has changed. The cleanliness of 633.636.628 after 17 minutes of operation is automatically rebooted and changes to 612.636.599. After restarting, the fans operate in emergency mode (at high speed), which results in a drop in temperature on the boards by 2 degrees. I wrote in support that I want to send you SMO and SM2 boards for repair.
