I love the fact that you cannot support your claims and then claim that you made no such claims. You entertain me.
Either:
Bitmain was wrong to control fan speeds (and you can factually support such a claim with data)
or
Everything you said was just meaningless trolling based on mere speculation.

You drivel on about how I should prove that "running the miners harder and hotter is the best option" while ignoring the 100, or so, times I've reiterated that the ROI is diminished at a far greater pace than any "improvements" seen by mere cgi file "underclocking" (never once have I questioned the validity of those, like Sidehack, that actually change things [including frequency and voltages] based on measured results). What good is a $1,200-1,800 miner that lasts 10 years and only produces a gross of $1,000 over the entire 10 year period?

Either present data to support your claim* or go back to your little troll-hole.



*surely someone with your level of certainty has charts with BTU output recordings to support your claim that manual fan speeds make the miners run "cooler" and more efficiently....
