extremely bad luck with noctua fans?

[dioporcoz]

Hi everyone, about 2 years ago i built my first pc and immediately replaced my fans with 3 Noctua NF-A12x25 PWM and, surprised by they're perfomance, i bought another 2 cause my dumb ass thought that i could just replace the fans of the cpu cooler not checking compatibility so i put them back in the box and have them as spare. about a year after the exhaust and 1 intake started to malfunction, they wouldn't spin after booting so i had to shut down and reboot my pc in order for them to spin until a month ago where i replaced them with the 2 spare i had cause i also replaced psu and case. now everything works fine, until about 3 days ago where the last not replaced yet intake started to malfunction too by not spinning at booting but spin fine after shutting down and rebooting but i feel im slowly damaging the other fans by doing this process just to make it spin (idk what to think now); after this everything works fine tho, 27°-30° degrees idle, no overheating during games and fans are responsive when changing speed and mode in aorus system information viewer but what are the odds of buying 3 faulty or to be broken in short time noctua fans? especially after hearing only good reviews and experiences by the majority of users.

build:
gigabyte aorus ultra gaming pro
rtx 2070
core i9-7960x
corsair rm750w

I think it's more likely to be your motherboard than it is multiple Noctua fans having the same issue. Do you have a fan curve set extremely low and/or fan stop enabled in BIOS?

I am confused. If the fan is not spinning at boot it’s most likely not getting enough voltage to spin... the mobo may be set to a silent fan mode and not providing enough voltage to get the fan to actually start spinning. Next time this happens, see if you can spin the fan with your finger to get it started and if it will continue to spin once you do that. If so, it’s the motherboard not providing enough power - likely a setting you can easily change.

 

As far as damage, I don’t understand. You can really damage a fan. What process would be harming the other fans..?

 

Also, if the fan eventually spins like normal, it’s almost guaranteed not to be the fan. They pretty much either work or dont work.

Check your connections to make sure the fans are securely plugged into the board. If you're using any fan splitters, consider disconnecting those and using a SATA-powered fan hub like this instead. Finally, a CMOS reset might not hurt, but I find it's a good idea to do those about every six months anyway.

 

I'll admit up front that I think very highly of Noctua fans and prefer them to many, many other brands, even with the price premium, but I would be looking down this road regardless of fan brand. That many failures doesn't seem like a fan issue.
