New h150i Reporting Crazy CPU Fan Speed

Just replaced my (second) H100i and went for a larger model to cool my 7900x. Everything went smooth and seems to work properly, but ICUE reports Fan #2 on my Asus X299 Deluxe board with a speed varying between 4545-4720 RPM. After a little trial and error in the bios, I realized that it wasn't a wacky case fan, but the H150i that's plugged into my CPU header.

 

Any idea why it's reporting such a high RPM and how I might rectify the issue? As I said, it reports the same speed in the BIOS. It's plugged in my CPU FAN connector, not my CPU OPT connector directly adjacent.

I don't know for AIOs, but usually pumps report two pulses per revolution, so the actual speed should be half the reading.

 

You're correct there. The "Fan #2" as reported by ICUE is exactly double the H150i's pump speed.
