Question Can I lube Gigabyte windforce fans?

[anotherhardwarenoob]

My GTX 970 Windforce started to make a rattling sound. So I am thinking about lubbing them, but I havent found any tutorial on how to open a windforce fan.
Has anyone here open a windforce fan to lube it? Can someone tell if that is possible?

If it is making new rattling noises, it needs to be replaced.
The clearance between the shaft and the bearing is now too large.

Lubing fans is, at best, a temporary measure.
