The one fan on my card has been slowing down over the last 2 months 3000>1950RPM now. With case fans I've always just poured some 3in1 into the bearing and they have been fine since (10 years+) Is there any way to add oil to the bearing or is is just get a new fan scenario? Just don't feel like taking it apart again to look

Warranty ended 6 months ago so I was just wondering if there was a quick fix as I don't have the money currently for parts and fans from my 1080ti won't work either
