Is the heatsink actually pressed down onto the chip? Also you may want to check the fan is spinning, if it isnt maybe you should check it is still plugged in to the PCB. If nothing is working to fix it, just contact butterfly labs. All their miners have a lifetime warranty doesnt matter whether you bought it new or not
