I've read I can simply take off the fans and add a drop of 3-in-1 oil or silicone oil?

Or do I simply pitch it and get a screaming fast 1080? :)
With fans that make it hard, or impossible to reach the bearings by label-pealing or hub-drilling, I have been able to insert a thin tube along side the wires to the motor, and get oil to the bearings from the side. This works best if you have the fan on edge so that gravity works with you. It has taken a bit of time and working the fan up and down on the shaft for the oil to infiltrate. Of course, you don't want to overdo it.
I have a squeeze bottle of oil which came with a built-in tube. Lacking that, you might improvise with a tube like those which come with canned air.
