Hi GoogalyMoogaly, both my XSPC 750 Res-Combo + MCP35X isolated from the case, made my own foam set up for the XSPC and just using the foam pad that come with the MCP35X. If you can try to shield the pump + res from the case even in the bays try 10mm wide one sided sticky foam, just a thought. If you are using a bracket to mount your pump put the foam in-between the case and the bracket faces so it soaks up some of the vibration.
