Well, you've already confirmed it's the third fan on the GPU. What further evidence would you like?
Your decision is yours.
You have three choices:
1. Accept the poor fan noise.
2. Send the GPU back under warranty.
3. Fix it yourself—either purchase a replacement fan and install it yourself, or take it to an electronics repair shop for replacement.
Choosing option three will cancel the warranty because opening the GPU requires removing parts that protect its warranty (usually marked with a small sticker covering one or two screws).
You shouldn't lubricate the bearing since the fan bearings are sealed and not accessible.
The cross-section of the fan shows the bearing is #5.

the reason i’m unsure is, then why was the noise still there, when i manually stopped fans one by one using my finger? i did that after i loaded Witcher 3, went to a foliage intense graphic area for the sound to come, and then did the entire thing. would living with it evolve this issue into something major later on? ps : should i try to update the GPU BIOS?
I'm a bit puzzled about this.
Why was the noise still present even after I stopped the fans one by one with my finger?
It seems like you're conflicting with previous information.
If the noise remains and the source isn't fan #3, you should retrace your steps and locate the sound origin.
For example, using a cardboard tube as suggested by @kanewolf.
Or explain your troubleshooting clearly so far.
When working through this, always change just one element at a time.
Be systematic and precise.
I told Step by Step what I did and what happened. If this wasn't clear, I wouldn't bother asking, since the only option for every electronic product is the same. Live with it, RMA or fix it yourself.
Manually stopping the fans was the first step I took when I noticed this problem months ago. I realized today that the third fan was the issue.
The emphasis now lies on addressing the noisy GPU fan #3 using current methods or alternative creative solutions. As for "acceptable" options, there are always compromises to consider. I’ll rely on those with deeper expertise in the GPU and its potential fan/temperature setups within your system.
It could be. There are several scenarios:
* noise intensifies significantly and consistently at any RPM.
* bearing rattle indicates direct contact within the bearing, leading to friction, wear, and heat buildup. Excessive heat may melt nearby materials like plastic.
* the bearing may seize, causing the fan to stop completely.
Typically, bearing rattle at a specific RPM suggests that lubrication isn’t optimal between the shaft and bearing. Adjusting RPM should improve conditions. However, the exact duration before failure is uncertain. Hearing bearing rattle should prompt replacement of the fan.
If the bearing were mag-lev (as with some modern cases), the situation would differ. Most GPU fans use sleeve or fluid-dynamic bearings, while others employ ball or double ball bearings.
What I did now seems to be working reasonably well so far. I used the Gigabyte software and adjusted the paired fans accordingly—higher speed for Fan #1 and Fan #2, lower for the noisy fan at 40% at 1000 RPM until it reaches 1500-1600 RPM at 95%. After that, I played Witcher 3 B & W for about 20 to 30 minutes without any noise. There might be a chance of noise returning later, but currently everything is fine. I aimed to avoid putting too much load on the faulty bearing fan.
It should work well since the makers allowed us to create our own fan curves for valid reasons (as long as we don’t always push it to the limit, hehe).
If you're concerned, you can perform a demanding GPU benchmark such as Furmark and check hwinfo64 for
GPU Temperature
and
GPU Hot Spot Temperature.
Your GPU also has a thermal cap—it essentially tells the card to reduce speed if it reaches this temperature to avoid damage. This limit can be adjusted according to your preferences (I use mine at 83C).
