I'm trying to check if my CPU water pump is working.

The fans spin on the radiator, it lights up and my idle temps right now are between 45c and 53c. Which is kinda normal on my build as I have a 7700X and this CPU runs pretty warm anyway. However, last night, my wife was using the PC and the temp was at 83c. She wasn't doing anything super intensive other than work. I'm home from work myself now and the temps seem to be fine, I was wondering if there's a good way to check if the pump is working. All I have is this screen cap from the Fan Control app I use and it show the Pump is doing something. Not sure if this is much to go on.

If your pump wasn't working, then no heat would be transferred to the radiator, and no heat would be dissipated. As such, your temps would continually rise until your CPU begins to thermal throttle. If you don't experience any CPU throttling, then your pump is working.

My issue is it doesn’t show the pump rpm in the bios. It says 0rpm and can’t hear any liquid movement. but the pc runs with good cpu temps. I am running the cooling system with an all in one cable plugged into CPU-FAN on motherboard that apparently controls cpu fan and water pump/radiator. Does this mean the pump/radiator fans are working but I can’t check them or is something amiss? I wish things like this would be explained because to a noobie like me with my first pc build it’s scary.
