Got my miner and power supply yesterday, got it all hooked up today. Seems to be running fine, but the power supply fan does not come on. I searched a bit but not able to find an answer, does anyone know if that is because it only comes on when it is over a certain temp? The power supply is just a little bit warm, and seems fine where the connector attaches. I am going to continue to monitor but a little bit nervous just in case.
