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.
