It is probably running at 1350 RPM with 2 decimal points (00). Fans never run that fast.

Yeah, that's either got a decimal or is a simple fluke / broken sensor.

If it were running that fast, without disintegrating, your computer would be lifting off right about now.

A 120mm fan at 135,000 RPM would have a tip velocity of ~850 m/s. A bit over mach 2.

The screenshot shows that your fan is currently (as of when it was taken) spinning at 1776RPM, which is a bit above average, but believable. Could be that it recorded a stuffed up max result. Try clearing min/max.
