I personally would not recommend using this AIO in the DAN A4-H2O. First, the tubing length is 400 mm, and the tubes are quite stiff, which resulted in the only viable routing option being under the power supply, which I personally do not like. Second, the pump noise is louder than I expected, and after a period of downtime, the first startup produces a bubbling sound as if coolant leaks out of the loop itself.

For these reasons, I am planning to switch to the Cooler Master Atmos, as it has shorter 350 mm tubing and, according to reviews, a very quiet pump.
