For all of the faults with the 84X model, you could safely run them in 110F temps by backing them down and then overclocking them in the winter. The 1047 model chews through PSUs, we don't even run their newest firmware because of that reason.
What faults? All of my several dozen 841's have been bulletproof - as in zero failures over the years - and are exceptionally tweakable. Their only fault is their efficiency is not the best.
I have 2 of the A1041's and 5 of the 1047's, zero PSU failures... Where are you running these to have so many issues?
