I recently set up my Asus TUF Gaming LC II 360MM AIO cooler, and I noticed something odd when checking the RPM with HWiNFO. The pump speed is showing around 4800 to 4900 RPM. I connected the pump to the CPU fan header on my motherboard since my board doesn't have a dedicated AIO pump header. My CPU temperatures are fine at 31 degrees, and the pump is quiet—so I'm confused about these RPM readings. By the way, I'm using an Asus Prime B660M-A motherboard. Can anyone shed some light on this?

If your CPU temps are good, it might just be that HWiNFO isn't accurately reading the pump's RPM. Have you tried checking the AIO's speeds using Asus's Armoury Crate software? That might give you better insights!
I ran into a similar issue! Even though it's an Asus AIO, Armoury Crate didn’t recognize it. It only reads my GPU and motherboard. I checked the BIOS too, and it showed 4800 RPM there as well. Seems like it's working as it should, just the software can be a bit off.
