People will say it’s dying and you need a new one.
What’s up buddies! I have been struggling with some fan noise on one of my two GPU fans (GTX 1070 Zotac mini). The fan noise started when I powered on the computer and after about 5min it was gone and that most have something to do with that the GPU got from stone cold to warm.
Anyways, computer noises are very annoying and it’s indicates that something is wrong and is about to break apart. But if your fan or fans is spinning but leaving a noise I want you to try this out first. This helped me and it’s spinning flawless and not a single noise on the start up. I think any cycling chain oil (not to fat oil) or sewing machine oil will work. You don’t need much just a small drop.
Check out this video, I did it exactly like this.
