Hi, I have a total of 7 case fans (3 intake, 3 exhaust on the upper and 1 exhaust on the back of my case) - the 3 intake fans were NZXT and they were aging (making loud noise every time I start my pc). Now, I replaced the 3 intake fans to Noctua NF P-12 120mm to eliminate the noise (which it did). In total, 6 of my fans are now Noctua NF P-12, and the last one is still an old NZXT but it doesn't make any noise and it is still running fine.
Now today when I run my PC, i was suddenly surprised when I looked at the temperature of my hard disk drive - it was at 40 degrees Celsius, good thing I had my temperature monitoring software. Had I not have run it, I would have run my PC for more than an hour. It was then when I found out by looking under my desk that all of my Case fans stopped working, however my CPU fan and graphics card fan was still spinning. I turned off the PC quickly and let it cool off. I did several testing again to figure out the problem, and for some reason - disconnecting and reconnecting the extension cable from the PSU to the fan hub made all the case fans spin again. I plugged in one of the new Noctua fans i bought to the motherboard's fan header (to test if the fan is still working after the incident) and it seems to be working fine, so I assume all of my fans are fine but the fan hub may be compromised.
Now with this event, I don't feel assured I can leave my PC away from keyboard as the fans may suddenly die and make my pc fry.
I am not very familiar with fans - usually I read on the net it is just plug and play.
Should I replace the fan hub as it may be defective and buy a new one? Should I just allocate some of the fans to be connected to my motherboard instead to reduce the "load" on the fan hub?
*Btw my case is a NZXT 580 - it comes with a fan hub at the back.
