Yes I did add heatsinks but I feel it would have worked without with all the glue removed.
Had same issue with Carbon Cub, removed excess black glop and seems fine now in a test CC. I installed a new HH supplied brick in my GOOD CC and it is doing fine. I paln on reusing old brick in another plane now.
