I have a new chronic problem with my HR10-250 locking up with the "internal temp was too high" message. It seems to have started with the "upgrade" to 6.3, but this could be a coincidence. I have confirmed that the fan is working and I am not using HDMI. In an effort to try anything, I removed the HDMI card completely and installed a second fan to circulate the air. No improvement. AFAICT, the unit is not that hot. The power supply heat sinks are almost cool to the touch. In fact, in cases where I have been able to check the sys info screen immediately before or after a freeze, it shows ~42-43. In one case, this sys info screen showed 16C! This suggests to me that there is an intermittent failure in either the temp sensor or the software that talks to it. - Has anyone else seen this (either with or without 6.3)? - Can anyone point me to the location of the temp sensor if I want to try to disable it? - Any other suggestions?
