I'd suggest you download HWinfo and monitor your CPU temperatures as well as clock speeds (start the program in sensors only mode).
I've used CPU-Z already to monitor the temperature and its said that its running at 100 degrees celsius, even though it is not hot at the touch at all.

What's not hot to the touch? the AIO radiator?
If it's running at 100C in IDLE that either means that the pump is not working or there's a clog in your AIO preventing water to flow through the radiator.

The AIO Radiator and the part that is over the CPU.

Well that's bad... there's no heat transfer from the CPU to the radiator.

I mentioned above, the pump might be dead or there's a clog.
Are you sure that the water block is mounted properly to the CPU heatspreader?
Yes, but I just made a discovery. I reached my hand further back on the part that is over the CPU and I could feel a large amount of heat. I think that could be part of the issue.
 
Yes, I feel vibrations.
Seems like the pump is working.

Can you just for the sake of it, remount the CPU block. Clean the existing thermal paste with isopropyl alcohol and reapply new paste... a thin vertical line down the middle of the CPU heatspreader should be enough. Tighten the screws on the water block in a cross pattern and make sure it is tightened firmly at the end.

I do not have thermal paste, so I will go out and by some and then see what happens. I will comment back on this thread once I have done this.

check how you AiO is installed.
as @ChumP said , remove the clear plastic protecting the part that touches the CPU

also check how the place : better place for the radiator is on the top of the case, exhaust. this way all air is traped on the top, away from the CPU waterblock.
front or rear is ok if tubes are pointed downwards
never install the radiator lower that the waterblock

BEST :
radiator on he top, air stay there.
your AiO should last a long time ad stay quiet and your CPU cool (well, for a 9900k)


OK -ish:
waterblock is slighty lower than the highest point of the radiator, tubes upwards
performance should be ok, but it's possible the pump is noiser than with radiator on the top. that's because some bubbles of air will be trapped in the pump.
should be better with tubes down if possible.



BAD :
waterblock is the highest part of the loop, so air get traped inside.
Very noisy and the CPU get hot



EVIL :
waterblock is filled with air and occasionnaly push some water through.
noise, vibrations, 100C CPU agonizing.
