Why are you guys using a secondary stratum proxy when BFGMiner already has a stratum proxy built in?

Because bfgminer's proxy does not support long poll.

I have been trying to find a discussion on this since I got these cubes. So at the end of the day, what does that mean for efficiency / mining revenue wise? My first guess is higher stale count without longpoll or I could be way off.

Is it normal for the fuse to be warm to the touch on high clock? I have 2 cubes, one doesn't like high clock, the other one seems ok but the fuse is warm to the touch. I have only had it on high clock for 4 or 5 hours now after running on low for a couple days, but I don't know if I should leave it on high or not.

I had one cube totally destroy the fuse, fuse holder and do considerable damage to the main board after a week of running on the high clock speed.
I have had to jury rig a repair using heavy gauge wire running to an external fuse. The new fuse runs hot to the touch (>50c), you can keep your finger on the fuse, but it is uncomfortable, on the point of starting to burn. One advantage of the wires is I can place the fuse itself in the airflow to the fan which cools it somewhat.

The design they have used, is that both power feeds are combined into one 12v rail just before the fuse. I think a better design would have been to keep the two high current feeds on separate rails each feeding 3 blades and have a third 12v feed from the power supply (there are usually plenty of those spare even on power supplies running multiple cubes) feeding the main board, fan and Ethernet port. That would spread the load out more

I guess I'll leave it on low clock for the weekend. It seemed mostly fine all day but leaving it alone over the 3 day weekend to test how well it handles high clock doesn't seem like a good idea. Touching the fuse portion where the little loop of wire is is definitely hot enough to burn. Not immediately, and not like blister or anything, but holding a finger tip there for a few seconds produced a red sore spot. Next week I'll try an overnight on high clock and see what happens.

Sucks you have to leave it in low power but definitely a good call granted you wont be there to monitor/babysit it. Do any of you guys run extra cooling. I know its overkill and maybe not feasible with a large farm but I have a house fan sitting behind my last cube and inside of a cold dry garage. I do this more for the sake of cases like this one, (stuff failing under heat) with efficiency/revenue coming second.
