First I thought this might be because it sounds like you still have your fan hooked up and spinning. Not sure if that's the case, but the only setups I've seen the fans are disconnected if I'm not mistaken. Either cheated at the control board or using immersion firmware. Then i had this thought.
Just looked up what the A9 is. Is this the grin miner GPU Looking thing? If so that says it draws 500w you are now using a machine that draws 3100w +. I would guess you are not circulating and cooling your oil well enough to remove heat.
