"It is connected" and "connected properly" are not necessarily the same thing. One photo where we could clearly see the connector is aligned properly would help us, to help you, determine if you need to replace the AIO liquid cooler. I understand your frustration, but this is a user forum, where users help other users. No amount of photos in this thread will get your part replaced. If you determine that your pump has failed and you want to replace the AIO cooler yourself, consider the Corsair Hydro Series H60 (2018) You might also consider replacing the OEM fans with some better quality, more quiet fans while you are doing maintenance.
The pump fan for the CPU keeps failing. After cleaning the inside I was able to get it to pass but the error keeps occurring since then and the BIOS software keeps throttling my PC. I've also already replaced the thermal paste on the CPU.
