The level of "this is bad" has reached new levels. I am paying a lot on electricity per kWh and right now I am barely breaking even. ETH is under $400... I am very very close to unplugging...

just breaking even here too if i count my bills , I might actually have to go back to work lol

Things are a bit tight for me, but no worse than 2 summers back right after I moved - though I have a LOT more hardware working to keep me at this level vs what I had then.
Litecoin dropped enough that I shut down the A2 farm - still debating if I want to go ahead and try to sell those machines or keep them for "just in case" I manage to get into a lower-cost area soon enough to matter, *or* pricing kicks back up/diff drops enough to make them profitable again.

Still working on the "reconfiguration" project, which should help a little - just got my first Mark II shelf/rack unit fully populated, now I need to build the second one and redo my airbox setup then I get to start reconfiguring some more.

*THOUGHT* I had a pair of my R9 290 cards go bad this weekend - but one was just a riser flaking out (I have spares) and the other the fan DID go bad but a left-over Delta 80mm 6800 rpm "screamer" from my Athlon(Thunderbird)/Alpha 462 heatsink days is proving to be "barely" enough to keep the card reasonably cool.
It's amazing how QUIET that screamer is compared to the MASS AIRFLOW through the cards though. 8-O

Turns out that while AMDGPU "supports" the R9 290, you have ZERO clock control and I'm not 100% sure the modded BIOS undervolting is working - fan control works though.
I may have to redo that particular machine with Xubuntu 14.04.03 and fglrx instead (mostly a matter of grabbing the HD out of one of the machines the R9 290 cards came OUT of and adding settings for more cards).

The AMDGPU + multi Polaris machine is working reliably now, with some undervolt and underclock via modding one of the driver kernel modules saving a LOT of power.
