Antminer S9 temperatures in STATS

[Morescratch]

Hi all, in the STATS from any given S9 I see:

Code:

            "temp1": 0, 
            "temp10": 0, 
            "temp11": 0, 
            "temp12": 0, 
            "temp13": 0, 
            "temp14": 0, 
            "temp15": 0, 
            "temp16": 0, 
            "temp2": 0, 
            "temp2_1": 0, 
            "temp2_10": 0, 
            "temp2_11": 0, 
            "temp2_12": 0, 
            "temp2_13": 0, 
            "temp2_14": 0, 
            "temp2_15": 0, 
            "temp2_16": 0, 
            "temp2_2": 0, 
            "temp2_3": 0, 
            "temp2_4": 0, 
            "temp2_5": 0, 
            "temp2_6": 76, 
            "temp2_7": 67, 
            "temp2_8": 65, 
            "temp2_9": 0, 
            "temp3": 0, 
            "temp3_1": 0, 
            "temp3_10": 0, 
            "temp3_11": 0, 
            "temp3_12": 0, 
            "temp3_13": 0, 
            "temp3_14": 0, 
            "temp3_15": 0, 
            "temp3_16": 0, 
            "temp3_2": 0, 
            "temp3_3": 0, 
            "temp3_4": 0, 
            "temp3_5": 0, 
            "temp3_6": 0, 
            "temp3_7": 0, 
            "temp3_8": 0, 
            "temp3_9": 0, 
            "temp4": 0, 
            "temp5": 0, 
            "temp6": 61, 
            "temp7": 52, 
            "temp8": 50, 
            "temp9": 0, 
            "temp_max": 61, 
            "temp_num": 3, 

My question is what temperature is temp6 reporting vs temp2_6? The temp2_6 value is what's reported on the miner status page. Just wondering because the temp2_6 value is always higher...

The temp6, temp7, temp8 are the air temperatures near the back of each board (bitmain refers to them as pcb temps).

On the other hand, the temp2_6, temp2_7, and temp2_8 are chip temperatures, so they will generally always be higher than the exhaust air temperatures.
