Yesterday I made a couple more tests after running it for a week at 1.5 Th and 1000W during the paycoin frenzy

First of all I did try to push it to the maximum, having a 1600 W PSU I though I could go higher than 1.7 Th, but alas I could not.
Intake temperature as reported by miner's interface is higher than environment's real one, I was in a 10 ° C as this old analog thermometer shows

but miner's reported temperature was at 16 ° C and increasing

At 1667 GH I was using around 1280 W on a 220V outlet with my Recom M1600 PSU (85% efficient)

1670 GH is as fast as it can go, in a 10 ° C environment, because of thermal throttling by the chips, which were not able to remain below 125C even at 100% fan speed.
In his review johnyj is doing some great mods to better cool all of the chips and so avoid thermal throttling, let's see what he can get.
