I have the following waterpump below. The res seems to have cracks in it (it has been sat in the loft for a number of years, so I am not sure if it came like that). Anyway does anyone know if this will fit? I have a smaller case so want a smaller res top:https://www.overclockers.co.uk/ek-water-blocks-ek-res-x3-tube-110-64mm-wc-9p0-ek.html or any other top?
