while driving to UPS office I've been planning how I'll cut wires of my 2 brand new PSUs, as pci-e extenders had not arrived yet. But in the box was a nice bonus: already installed pci-e connectors!
there were a lot of bonus thermal paste all over the device
Too much thermalpaste is not a good thing. If the miner runs too hot you/us may have to re-paste it.
On a different note, what do you guys think of adding a second fan to the miners? I'm guessing the main fan is one of those crazy 150 cfm server fans so adding an slightly weaker fan to help it out a bit should be OK.
