@david_3108-yahoo-fr said in Fan / temperature issue: device continues to work fine, except the noise of the fans at max speed. I tried to set the fan speed at a lower level but it turns auto after seconds. I check the device temperature : it starts at 40°C, after 5 minutes, it reaches 55°C and after 10 minutes, the temperature is around 70°C. It remains between 70°C and 73°C after hours of use. It seems to me that the temperature sensor has a shift of 20°C. Does someone has faced the same issue ? What can I do ? Old post, but I have the same problem. I've been wondering if it could be dust build-up inside the projector. I'll probably open it one of these days and check.

or is there some way to root the system? I can't do anything so I think I can't solve the eth not connecting :/.

It's very convenient not to answer questions, just ignore them!!! There is no answer to any question! A self-respecting company doesn't do that!
