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.

Hi, it doesn't have to do with heat, cause the miner was broken in under one minute since powering it in oil. The oil was still cold.

Can you explain in more detail how you have the oil cooling set up?

Something sounds seriously wrong to have smoke bubbles.

I didn't get to the point I had to cool the oil. It all happen in 30 seconds. Funny thing is the miner was still on, though never connected to mine.
For the record I had a radiator with 9 fans on it but the oil was still cold.
