Also, I noticed there's another fan in the "official" power supply. Since I'm planning to run it with very low power, I wonder if that fan is even needed as that's now the main contributor of noise. I guess I could buy another PSU without a fan for this "silent miner" project. Any suggestions for one? So far I've found
this one, which should run without starting the fan until 220W so it should be absolutely noiseless.
Been using a couple of these:
https://www.parallelminer.com/product/z9-mini-power-supply-460w-110-240v-80-platinum-94/They are running 1-Full + 3-Standard on balanced, and can be paired/controlled together. The fans do move a little air, but I can't hear them. (only feel it coming out the back)
They appear to be sold out at the moment, but you can pick up the breakout boards / cables from above, and source the PSU used. I use the same ones in my old G8 HP servers, and you can pick them up from old server distributors for cheap. ($10-20) They are dead nuts reliable, and efficient. The Titanium versions are a bit harder to come by, and not worth the extra $$ to me. Standard Gold versions work fine as well, but they are usually almost the same price as Platinum.
4mo uptime here, BTW. Would be longer, but had a power outage during a snow storm a while back.
