I'm not sure what you are saying. I think you are saying my want for less heat is not realistic?
Of course not, I'm just adding one more condition that you don't write above on your last statement.
I mean this:
I would like lowest power consumption with highest hashrate.
Even I was able to reduce much heat at my rig with a few things, so that was realistic after all.
And that I should aim for stability more than anything?
That's me, I didn't say you should do that. But for me stability is important.
