Just to be sure, are you looking at this info in iCUE, or in BIOS Setup? iCUE may NOT be working, so do not rely on its info right now. BIOS Setup will give you info. Depending on WHICH mobo header your things are plugged into, that info MAY differ. IF the PUMP is plugged into the CPU_FAN header, it may tell you that it is a "fan" when it is not. However, IF the pump is plugged into a mobo PUMP header, it will use that label BUT the CPU_FAN header will tell you there is NOTHING there because there really is - the pump is on a different header.
If the PUMP speed is NOT shown on the actual header it IS plugged into, try to disconnect it and re-connect it a couple of times. There MIGHT be a simple dirty contact in the plug. If that does not give you a pump speed reading, the pump MAY have failed. You can test for that when your system is in use and has warmed up feeling hoses for temperature, in two places. First, at the PUMP, feel the two hoses there right at the pulp connection points. One should feel a bit warm and the other a little cooler. If they both are quite warm and equal, the pump may not be working. Now follow those two hoses over to where they connect to the rad unit. Again, compare them. If one iis slightly warmer than the other that is normal. If both are equal and cool, then the pump probably has failed.
The "find the USB 2 Device" thing is in the Windows tool called Device Manger. To get there, type device manager into the search window at bottom left, then hit Enter. You'll see a long list of devices, and there MAY be a mention of Corsair devices. Of that does not show clearly, go to the bottom and expand the list of Universal Serial Bus Controllers to show you the USB devices the system can "see".
When I said "reboot", I means just a normal shut down and re-start your machine. This does NOT make ANY changes that require re-adjustment or installations. In this particular sequence, all that does is cause the machine to re-start normally and recognize that its Device Manger list does not contain any reference to some real devices, so it detects their presence and updates its list to where those items really are. All this is automatic, and may simply show you some notices of what it is doing. No actions required from you.
