With this mounting solution, a HEATKILLER® D5-TOP pump top can be mounted on a 120mm fan. It's also possible to mount it onto a horizontal radiator or 120mm fan mounting holes.The top part can swing freely and is decoupled from the bottom part via rubber dampeners. No vibrations will be transferred from a HEATKILLER® D5-TOP pump top to the PC case when it is mounted with this stand, resulting in ultra silent operations.
