[SOLVED] One fan on my graphics card randomly starts spinning at full speed

[TalSO]

I have a Sapphire RX580 SE.
Lately it started doing this weird things where one of the fans starts to spin for no reason, at very high speed.
This happens regardless of GPU temp or load (including when the it really isn't doing anything and is at 25C).
When the fans should kick in (when temps rise), they do both work as intended.

Any thoughts on suggestions for making this random fan action stop?

That sounds like a faulty fan.

Being the fans are generally wired in parallel...they should both be receiving the same signal.
If one is acting up...I would think it would have to be the fan.

So, I get that the recommendation is to replace the fan itself?

Yes. They generally have a pretty good selection on EBay....and I think they come as a set.

You could switch fan places and see if the offending fan randomly starts spinning.
Replacement fans are available on Amazon, eBay, Newegg, etc...just search for "Nitro Fan"

Cool. I'll try those things when I find some time for it. Thanks!
