Anyone else notice their A3 running pretty hot on the chip side? Mine was approaching 90C on one board, had to go in and manually set the fans to 100%. Now running low 70's. This is with 70F ish ambient temps. These run quite a bit hotter than my L3+'s it seems.
I had to do the same, other miners (L3+s) in the same place are working at 50's.
Bitmain OC'd the shit out of these, just like the D3. Hopefully blissz will make firmware for the A3, he saved us with D3 firmware. It gives the ability to change voltage and customize each hash board with voltage & frequency.
