awesome input guys, thanks alot,
very interesting! watching this.
Got a hacked S7LN keeping the shop bathroom warm, just turned it on today as we enter a cold snap. Got an undervolted S7 for heat in my apartment that's also pretty quiet. There's another one running around the shop somewhere too.
I wish the S9 were more hackable. It'd be nice to run one cooler and quieter. I know the chips will operate up to at least 400MHz down around 420mV, which probably isn't much of an improvement over stock settings (about 7% lower voltage, so maybe 10-12% efficiency boost machine-level) but that would turn it into an 8.5TH 700W miner, which surely can run quieter than stock.
If they were more hackable.
yeah that would be cool, I have one old s9 that you can change the settings on, still pretty noisy, might try that with better fans, keep an eye on the temps tho.
still tempted by r4, seen a few you tube vids of some running, psu louder than unit lol. they are cheep now.
thanks for all your input.
