So all was great, but there now appears to be an issue... one of the fans keeps on dropping to 0 rpm then revving all the way to 3500 for absolutely no reason, temps never tops 60 degrees. It isn’t limited to gaming, i happens randomly.
Bummer then, get that card swapped/repaired. Most likely the electronics in fan itself are failing as most commonly those fans are on a single parallel bus so probably the card itself is okay since only one fan has the problem.
I would actually suspect it is a part of the pcb, that has failed, specifically a part that is telling that one fan what to do. If the fan had failed, i would suspect the fan, but it is still very capable of hitting full rpm, it just doesn’t seem to know what rpm it needs to maintain, to maintain the fan speed.
