My Compac runs @ 312.5MHz with 1 HW error maybe every 2 days. Decent USB charging hub that is supposed to provide up to 2.5A per-port groups, 7 ports for total of 60W. It's also feeds 2x of Sidehack's (Gekko)  2PAC sticks

Yes, even with a fan blowing on them they are quite warm but then again, seems mining ASICS love high temps.
