So let's summarize: I can use BrainsOS+ on solo pool and there was a proof that this software can find block. Am I correct?

I'm using different software for my antminers because of custom cooling and I want to protect the device if that cooling will fail (also autotuning option convinced me). I cannot do this on Bitmains software as it has disabled any access into it (tried to ssh and telnet but without success) and without fans it won't start. I know that with access to shell with root I can "cheat" any sensor to make it run  (I'm linux daily user and DevOps engineer so I believe I have enough knowledge to do this).

I heard about Vnish which is using open source software under the hood but I can be wrong.

Do you have any suggestions how to solo mine "the right way"?
