I concur. Its working at spec speeds (presuming you bought a 13TH unit not a faster one). Chances are the sensor is bad and reporting false information. If it was really that hot it should have shut itself down.
Mine on, or open a ticket with Bitmain.
I believe the issue is with the sensor. because I left it off for one week and just now switched it on, and everything looks good. any idea where the temp sensor is located on the board?
