Pumps in the field of computer cooling have not changed for the better. I notice that there is still the biggest enigma to produce a good rotor. Well, if it does not go differently, they should look at what the pump for 30L / s looks like in the city water pipes and then copy it into a smaller form! The construction of the ceramic pump is a good step forward, but here only the copy of the D5 pump rotor, which is closest to the good design, was copied, not improved .Here, and in most products of such kind, is forgotten that it is best to carry out a lup by pulling the water off the tank then, the pumping is constantly in the vacuum. To better understand the pump is mounted to drain the liquid through the system and after cooling from the radiator and drain it into the tank, and then pull it out of the tank and do not push it. This method greatly reduces any consequential pressure blades. although this pump also has push characteristics, its lower consumption is also the biggest weakness. Hopefully, with the given opinion, I I hope i give you a better view of the behavior and operation of the pumps and allow you to more deliberate assembly of the lup. Good luck!. All this is said about this pump.
