I'm experiencing an issue where temp3 on the avalon unit always shows a value of 0.

I believe this is the sensor that is affixed to one of the module heatsinks in some thermal paste of some sort.

I traced this back to its connection on the board, it appeared to be seated correctly. I unplugged it and re-seated it, with no success.

Any suggestions? I am afraid to keep it running, as the fan speed stays very low and I do not think it is providing adequate cooling due to low temp3 sensor value.

Thanks.

temp3 should be the param control fan.

Although I know nothing about the hardware, I think you should take a picture of what sensor you reseated, so may others can help.

My understanding is as follows: 'temp1' is from sensor mounted to one of the air intake fans. 'temp2' is not currently used (-1 value). and 'temp3' is from sensor affixed to a module heat-sink.

After scouring the forum for example copy/paste of stats from other users Avalon, and confirming with an additional Avalon user on IRC it seems evident there are 2 temp sensor values each being reported through 'temp1' and 'temp3', respectively. I apologize for the earlier miscommunication, I was not trying to assert there should be 3 temperature values reported.

The issue with this particular Avalon unit I have, temp3 has a constant value of 0, and the fans always stay at ~700-800 rpm, even after hashing at ~66 GH/s for 20 mins+. I have turned this unit off to prevent damage.

Picture of the sensor connection that was re-seated (with no change to the temp3 '0' readout) is below.

Thanks for your time and assistance, any suggestions would be greatly appreciated.
