Hello,

motherboard - Crosshair hero viii wifi
cpu - ryzen 9

I plugged the ryujin to "AIO_pump" connector in the motherboard (these are for the fans connected on a splitter) and on "USB1213".

CPU_fan error - I set ignore in bios.


when PC is running normal. only 2 out of 3 fans of ryujin 360 were spinning, i checked all the wires, they are all connected.

why some fan(s) are not spinning all together?

Thanks in advance!

I just built my computer, Crosshair Viii Dark Hero, with the Ryujin 360 and I plugged the CPU fan to the nearest fan header. It did not like this and I got the same message you did, CPU_fan error. So I moved it to the top of the motherboard, as there are 3 fan and pump headers there, and everything worked after that. I'm not sure why the 3 fans are not spinning together. I cannot see the fans most of the time but if I look I have noticed they are not always spinning. Could be you got a bad fan or one of the wires has come loose from the connector. I watched a YouTube video from JaysTwoCents where he reviewed this AIO and he had wires come out of the connectors. If your temps are getting too high you should be fine.
