Cooling fan weird issue

[JeeBoo]

Hi everyone,

last night one of my cooling fans started acting weird, it basically starts spinning and then suddenly slows down with rattling noises and comes to a full stop and then it repeats the cycle, computer is booting normally and the rest of the hardware works fine including 2 other cooling fans. Any ideas what would cause that?
PC - Power Spec X601 water-cooled
i5 9600K
GTX 1070Ti
16gb ram
390z motherboard

I’ll include a link with the video:

Thanks in advance

Hello

Could be your fan is going bad… You may want to consider replacing that fan..

Try the simple thing:

Swap the connection of this fan with the one next to it.

If the new arrangement has no effect -if the problem remains on the previously errant one, then do what vger suggested.

If the problem disappears and the previously functioning fan you connected starts exhibiting the same symptoms.. ..well that’s another story..

Any updates?
