I have my Maximus V Formula system up and running. In the process of getting it to boot I discovered that the motherboard will not power up with the power supply connected at the 4-pin EZ_PLUG location at the bottom of the board. If anybody has a comment about that, please share. At POST time a 'CPU fan error!' message is displayed. I have a Cooler Master Hyper 212 EVO - CPU Cooler with 1 120mm installed and the fan is running when the system is powered up. The CPU cooler fan is connected at CPU_FAN. If anybody has a comment why I get the message at POST or how I can get rid of the error message, please share. Thanks.
