During the development of the Ultitop D5, attention was paid to optimal flow behavior, resulting in extremely quiet and smooth operation. A mounting ring made of anodized aluminum and a matching seal are included for mounting a D5 pump (not included). A mounting bracket with silicone decouplers specially developed for the Ultitop effectively prevents the transmission of vibrations to the computer case. Stainless steel plates with M3 threads are inserted into the silicone decouplers for mounting. The mount can be detached from the Ultitop by loosening a single screw for easy access to the pump.
