USB OTG jumper removal, thermal difference.

The wiki states that you can "reduce the power consumption and heat significantly." but doesn't state how much is "significantly" is. Is it 3*C under load? 5*C? Is it just the heat of that part of the board? I'd like to know the overall difference to know if I need to buy a power adapter because if we're truly talking about significant differences then I'll go ahead and buy it.

It's about 7-8C when idle.

The idle temperature depends on governor, ambient temperature, case. With the jumper not removed my C2 would idle at around 55-57C. With it removed it idles near 50C. I also have a C2 with a modified blue heatsink that idles at around 45C.
I haven't measured power consumption.
