I think I know what the problem is now!
Not entirely sure if you were referring to this but you definitely reminded me of this.
So I took apart the fan and the heatsink when I cleaned everything and there is this triangular thing that attached to the part of the fan with the magnetic coil and stuff. I had to pop it out in order to access the section where I needed to apply the oil.
I think I forgot to pop it back in and merely pushed it back without going all the way cuz it reached the point where I had to pop it in.
Does that make sense at all? Would I have been able to screw everything back up together if I in fact didn't pop it back in?
Also when I try to move the fan by hand its very hard and requires quite a bit of force. I guess that because I forgot to pop it back in. It should be rotatable by hand very easily right?
This is the triangular thing I referred to
and this is my card
I should be able to rotate that fan thingy with the sticker quite easily right?
