Fan Spoofer for immersion Colling and firmware

Hope this in the right section.
As I venture into the world of crypto mining more for Bitcoin at this point. I am looking to order my first immersion cooling system, that done. i have a deal on 40 Antminer T15, that on the way… today i was told that the T15 does not take well to being “dunked” as the firmware does not really allow the fan spoofer insert to work… have anyone put T15 in immersion cooling and how did it go?
