Randomly booted up my PC one day and got this error message
I went into BIOS and checked to see the RPM of the pump fan but it said N/A so I unplugged the pump fan cable and cleaned everything just incase this was the problem but even when I replugged the pump fan cable in I still get this error message. I have also tried updating BIOS to see if that was the problem but have had no luck. I can still use the PC however the CPU fan is extremely loud and I have no idea what to do.
Solved! Go to Solution.

on some systems the cpu pump and the cpu fan(s) are both powered from one fan header or two fan headers and if either pump or fan fails you will get a Fan failure warning on startup and you will need to determine if the error is due to pump or fan failure

@Tom_Kuit -- where can I find out ?
Start at http://PartSurfer.HP.com and do a search for your model, to get a complete list of components.

AIO's (All In One" systems are sealed units of the pump/cpu cooling block and radiator/fan you can not replace any parts as it's sealed system that is not designed for parts replacement, you must replace all AIO parts, the only critical item is the radiator size 120mm/240mm/360mm this must match the old units size if you want to use the same mounting location for the new AIO
