Questions about SMC U42 and speeds

After taking the first video, and running on high for a while, I noticed it was spinning faster. Any ideas how the fan can spin faster by itself, without having the capacitor replaced? And no it's not the bearings because spin down wasn't short in first place. I just find it really weird. It went from 220 RPM to 300 RPM on high, and low speed was more than 2X faster.

I'd provide a theory if this weren't just another cockamamie ploy to get more views

I didn't post this to get more views, I posted this because I found it weird it would spin faster after running for a while.

SMCs are known for crap bearings, so no surprise

Like I said, it spins freely to begin with. And it's older U42 with Laguna switch housing and I don't think older SMC have bad bearings.
