Howdy.  I just wanted to share my little experiment with the sidehack stick.  I have two and was running them at default setting with no cooling for a while then I decide to slowly ramp up the power and the cooling.  I've now got both sticks at 800mV and I've been running a day at a time at increasing clock rates.  I'm now at 425mHz on both for about 4 hours and with an 80mm fan each, probably overkill,  the sticks are hot but I can still grab the heatsinks and hold on and not get burned (my scientific temperature measurement).  I had 450 for a while but I think I didn't ramp it up slowly and I think I caused a surge so I had to go back to 425.  I'm running cgminer on ubuntu 14.04 on my xtra laptop and the sticks and fans are connected to a powered 12V 3A 10-port usb 3.0 hub.  hub is also plugged into the 3.0 port on my laptop but I don't know if it's getting any of that ports power.  These sticks are really well built and I'm having a blast tinkering with them.  I ordered 10 more last week and I can't wait to set them up.  Keep up the good work, I can't wait to see what your next project is.
