Nebor Posted July 15, 2020 Share Posted July 15, 2020 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. Link to comment Share on other sites More sharing options...
LeDoyen Posted July 15, 2020 Share Posted July 15, 2020 I don't know for AIOs, but usually pumps report two pulses per revolution, so the actual speed should be half the reading. Link to comment Share on other sites More sharing options...

You're correct there. The "Fan #2" as reported by ICUE is exactly double the H150i's pump speed. Link to comment Share on other sites More sharing options...
