Hi everyobdy this is my first post to this forum!
Some time ago I bought five Noctua fans, one NF-A14 and four NF-F12, but now I have encountered a problem which is worsening all the time.
So the thing is that some fans spin for few seconds after start up and then they stop and just sort of pulsate. This doesn't happen every time, before today it has happened few times, and the fan this happens to seems to be random, sometimes it is the front fans (connected with Y cable) and sometimes it is the side fan and today for the first time it was the top fan that wouldn't spin. Only the CPU fan seems not to be affected.
All the fans are connected to the motherboard (Gigabyte Z87-D3HP) and my power supply is Corsair CX600 which would be my first suspect for causing this as I have heard it is basically a ticking time bomb. But do you guys have any ideas, is it the PSU or the motherboard itself that is causing the problem? Oh and one more thing, if i plug fan to the motherboard while the system is on it blue screens after few seconds. This doesn't seem to happen to my friend who owns system almost identical to mine and the same thing for the fans as he has no problems supporting five Noctuas with the same board and PSU.
