My experience with the A3: Total of 4 purchased direct from Bitmain. All are overclocked by +668, running in a 2-car garage with the door closed and zero ventilation, along with 4 other ASICs and 1080 Ti x16 GPUs. Mining non-stop since January 27th with zero reboots, averaging > 900 GH/s per A3. Have no choice but to give it 5/5 stars so far.
Could be because of the clean power: all are fed dedicated 220V 30A, 2 units are using EVGA 1600W T2, rest are on AW3++. Also keep the units low to the ground where the cool air stays, tho the garage stays around 90F+ (outside temps are 50F). Bitmain says operating temps max out at 104F, so fine solution until Spring/Summer.

My A3's been acting up ever since day one and I think a hashboard just died on me. Temperatures are really low, with the outside cold the chip temps are ±60C. I see spikes in HW errors on all boards (bursts of 10k's of errors, leading to stale/invalid shares, and the one with the least amount of errors just left the building... Weird!
