My old overclocked situation:
615 Mhz /1235 mV -> 5.1 Th/s at 158 watt AC input.

Now:
557 Mhz /1150 mV -> 4.39 Th/s at 112 watt AC input

for 16.4% more hash power, I need 41% more power

Is this with cooling the VR or by adjusting the freq/power?

Just adjusting freq/voltage.
I haven't changed anything in the cooling as of yet.
Arent the VR's already cooled ?
I think the heatsink is rather fragile:
The 3 VR's at the PCB:

And the heatsink

Yes, the VR already has a heatsink. I repasted mine and increased the fan speed to cool it down further
