Can't be heat because the miner didn't had tha chance to sync and start mining.
I used paraffin oil pharmaceutical / cosmetic grade.
Fans were and are working even now if I power it up as does the entire machine. It does power up and just won't sync or do anything other than staying idle
I ll try upload a video in an hour or two.
