Hello everyone!

I recently finished my first build just a few hours ago, but I've run into this little error. Whenever I start the computer (Power on) It posts, with the ROG logo, and then runs straight into the AmericanMedia boot screen which detects all of my hardware fine. Unfortunately, I get a CPU fan error, which prevents it from going to Windows 7 and I have to go through the Asus UEFI BIOS and manually boot. It says

CPU Fan Error!
F1 to setup.

I'm running a Kraken X61, Asus Maximus VII Hero, and GTX 780 6GB SC. Along with some Corsair Vengeance Pro 1866mhz RAM.

I think the problem stems from the fact that the Kraken has 3 connectors. an internal USB 2.0, which I've plugged into the motherboard. A sata power connector that supplies pump power, along with power for 2 fans (Bitfenix Spectre Pros) which are on the radiator, and a 3-pin fan connector. I plugged the 3-pin fan connector into the CPU_FAN Header, which is 4-pin. Could it be that the mobo is attempting to regulate the speed at which the fan runs, but because it's a 3pin connector it can't, and that's what's giving me the error? Please let me know, and thanks for the help in advance.

-Ian

I did that. Accidentally tagged ya as best awnser, but the Kraken X61 also has a seperate 3pin fan header.

This may be resolved by now, but I had the same thing happen to me. I had the CPU fan cable plugged into the "PWR_Fan" port instead of the "CPU_Fan" port. Once this was done it started up properly with no issues!

****

also the port CPU_Fan port is a four prong connection, even though the connector only has a three prong female connection
