Hate to be a buzzkill but at 10 cents a killawatt you're better off on unloading them before the Antminer S7 comes out and it is a larger supply due to unloaders.

Well like I said let's not get caught up on the economics right now, few potential ways to toy with the kw/h price but difficult / not worth the effort without some results at the very least, and scale makes a big difference as well. That all really comes down to margins though and that isn't my focus at this time. I'm after first hand operating experience and actual data of my own to work with, I've done web searches / calculators etc.. which have been a good guide, but it's not the same. Of course, I don't really want to operate at a loss, so cost of kW is still a factor to some extent, as are the delays in getting up and running with the expected s7 release. Unloading would definitely not be a terrible idea $ wise, but the s5s should get me much of the info I need, hopefully in time to make a decision come s7.

at 10c a kw/h he is good for around 120,000,000,000 difficulty.. so no worries there..

for OP..
first thing i would do with the s5s is disconnect the PWM (usually blue wire) from the fans. if you are careful you can pull them from the plug with a needle and not damage the wire so you can plug it back in later if you want..

this will set them to run full speed and lower the temps from what they would be if left alone.

Yeah chopped the PWM wire first thing, I'd seen some stuff about the s5 cutting the fan on network loss and boards getting fried, and had no real reason not to run them max anyway. I've got a box load of 120mm collected up from PC builds over the years, they vary in quality but might chuck em on in pull for that little bit extra, not sure if the designs all that well geared towards push/pull, but can't hurt, I think.
