For the second one, try flashing it again with 1V1, it shouldn't go (much) above 1.1V though 1.11V wouldn't be unexpected. Does it go up to 1.15? You don't need to keep the bottom heatsinks warm during operation, the issues with the boards needing to be warmed up prior to startup with a hair dryer is exclusive to the boards made by Lucko. It shouldn't have an effect on your board.
Thanks, I was wondering about the hairdryer thing. The problem board does get above 1.15v in cgminer sometimes - that seems to be the majority of the times it's crapping out (bfgminer doesn't show it getting that high when it craps out). It also sometimes now does the 200+ GHs with practically all errors too, if that info helps.
The "hairdryer mod" is only good for boards that "stick" just under 1v it just gives the warm up a bit of a push.
The secondary cooling is mainly to move the air under the board. Heat rises, so the spill off from the main cooling fan is enough to ventilate the top.
A thought has just struck me, Will the Lucko boards with a problem work better upside down!!!!!!!!!!!
