I would really like to catch up on this... I've done running blades on proxy, but never could figure out how to get the other miner hardware to get with it.

Could you show and tell a bit more?

Received a 1212SHE today and must say that these are great... miffed at myself for not ordering enough for all S5's, but will outfit all of them with this fan.
For anybody else following the thread here: The connector has 2 ridges that prevent the connector to slip on the pins. I took a nail clipper and trimmed the 2 ridges down, with the result that it fit right away just fine and it works great. Dropped the most 'whiny' machine by ~20db.

Does anybody know if the S4 fans are the same as S5?

I also decided to slightly deviate from Stratobiz's strategy and test to 'hang' the S5's instead of zip-tie to the metal rack. I have some miners sitting on Metro Racks and the vibrations sometimes resonate the metal. Found a good length of 12 gauge insulated copper wire and it should suspend a miner securely.

I don't have the luxury of a 'facility', so I might not overclock right away and decide later if it is feasible with noise/heat in my basement.
I also don't have the PSU capabilities yet. Those 1300 watters are pricey... I was actually looking into getting Rosewills Lightning 1300's as they seem to have
8 PCI-e connectors, which would allow me to run 2xS5's at least at default settings.

Thoughts of course welcome ;-)
