That'll kick an intel CPUs ass. Overclock it correctly dude. Tend to get more(ghz) for less(volts) if you do so.
Edit: Might have come off as a prick. Sorry about that, wasn't the intention.

No worries mate, as long as I am getting useful information
Now, I am getting 1.27V on stock/auto settings under AVX stress. This is at least what OCCT, CPU-Z from Asus and Aida64 version of it tells me.
Forgot to mention - I also did run a test with Core Voltage set to 1.25v in BIOS, results were a bit better.

As for airbubbles it will calm down, you may need to follow a 'bleed' process like you would with a normal WC loop. Easiest way is leave the CPU block attached and hold the rad up vertical, hoses at the bottom and the rest of the rad above it.

Hey Tom, long time no see. Many thanks for your input, I know how busy you are.
Yeah, bubbles sorted! That is exactly what I have done to get them damn bubbles out of the way, I guess its a logical solution.
Now it sounds alright, although the pump still whines once it goes from 1000rpm (as shown in the Asus fan calibration software) to something like 1300rpm... definitely noticeable. Not sure how it compares to your favorite H100 and H100i.
It is one of the annoying high frequency sounds, so it does get on your nerves especially if the pump is pushed even higher.

Just waiting for a few other key components to come in before I start doing my manual adjustments. I suggest you follow the overclocking guide on this forum to achieve the best result for yourself.

WOW! I have not seen my go that high O.o
My first reaction to the problem actually was to double checking Tom's underclocking guide. But my CPU did not really like it that. I will give it a shot tonight again.

Ultimately what are your fan speeds, pump speed (you really shouldn't have this varying! set it at a static speed somewhere between 60% and 100% DC Voltage controlled) and what's the ambient temperature like.

My thoughts exactly. Cant imagine the manufacturers to it up that much for the whole platform. A little bit high on the volts - possible, but that mental?!
Well the air is definitely still there. But the mount was re-seated just to exclude that option.
Judging by the spread it was good the first time (I am judging this as I have probably took apart 100 laptops by now, and yes I know that they are different).
The screws + mount are tight as a nuns ... Did not go mental, just screwdriver/finger tight.
I could tear it apart again and take a picture and some point.
And YEP, the pump was set up for DC voltage in BIOS, as after a reset it jumped back to PWM.
I will try getting the voltage down for now by underclocking it again, maybe this time it will go better.
One thing I have noticed, even though I understand the fact that my fans and pump were set up to ramp up with the load, the temperatures were jumping around a lot. Lets say I would reach a peak of 80-85c at the Max Temp section of OCCT - while the RPM is reliability stable, the temps jump around from 80c to high 60s and back to mid 80s
Stress
I am also adding a screenshot of a quick and dirt stress test Asus fan profile for everything was set to FULL SPEED. In other words they were running at their full RPM.
Idle temps with fan speed set to Standard (was getting def by now). You can judge the room temps from this.
I did build this system to eventually include a GPU after some planning and modding, but mainly I wanted a silent and compact-ish/portable rig to work by. I have two Alienware M17X R4 sitting next to me, but I am tired of the noise especially since my work revolves around them even at the main daytime job. Hence the build...
Hope you can shine some more light guys! Many thanks!
Not many knew the fact that this netbook was a unicorn with a proper socket for a CPU, not soldered.
