Here's a list of miners that I've set up before: ASICMiner Blade, Cube, Tube, Prisma, Avalons 2, 3, 4, 6, and SpondooliesTech models SP10, SP20, SP30, SP35, plus a few Technobit models and Bitmain AntMiners.
The noise really comes down to the PSUs. SP30 is quieter and has a lower pitch compared to SP10 in quiet mode. Just a heads up for those running at 110V, you need at least 13A cables.
That's interesting. But sometimes I wonder if beauty matters when we deal with power and heat issues. These chips could perform better with more power, and noise could drop significantly if we switched PSUs or went bigger.
The first image was just a CAD design. Mine didn’t come out right, so I’m fixing the lighting. The real SP30 has different heatsinks and is silver, like the SP10.
I’m planning on using two outlets on different breakers. Running the numbers, an SP30 at 4.1TH at 2600W gives a better hash/Watt than 4.5TH at 2900W. Hash/Watt is what really counts.
@marvell1 You’re missing the point. What really matters is $/GH and the operational costs. A higher hashrate can reduce $/GH and lead to faster ROI, especially with low $/GH/m.
