And let me not forget one other significant thing; this unit has water cooling. NO MORE NOISE. There is a God!
That's a common misconception... You still
need a noisy fan to cool down the radiator in a water cooling setup. Unless you have a fancy setup hooked to swimming pool or other large body of permanently cool water.
Well you need a fan but it doesn't need to be noisy. However you are right in the longer context. Water "cooling" is actually a misnomer. The water is merely a heat transfer system. Much like a copper heat sink is a heat transfer system. Nobody would call that "copper cooling". Note this isn't a dig at HashFast the term is "water cooling" it just happens to be inaccurate.
HOWEVER the advantage of water cooling is that water is an amazingly good heat transfer system (transfers about 25x the heat per volume of fluid). So you can move the heat to a much larger areas like a radiator with 1000x the surface area of the chip and use fewer larger slower fans. No noise is a mismoner but it can be much quieter.
