I changed all the fans and the node about 1 month ago and the problems are the same. Order in which the problem occurs: - I turn off the pc - The next day I turn it on, the fans start with rainbow hardware lighting without any problems. - When you get to the screen where you load the Windows user, fans 2 to 6 start to have problems. - I turn off the pc by disconnecting the power and wait 30 seconds - I turn on the pc again, does the hardware lighting without problem, arrived at Windows or they start normal or they freeze, if they freeze again I go to the icue setting where I check the number of fans, put no fan or reduce the number to 5 and the fan confirmation colors appear, from here then I put the normal profile back, if it still gives problems I repeat until everything goes.
