Ah yes, I see, that was a bit unclear. The Corsair was mounted underneath the top "roof" with fans above the "roof" holding the radiator in place, and another set of fans was mounted directly to the bottom side of the radiator (push/pull). The problem with hanging, was because I could only put a few screws in to hold it up. The weight of the radiator with the fans etc. and the missing screws - as they could not get a firm grip - made gaps between the case and the radiator. The cooling effect was thus less because the air was blowing out in all directions instead of going through the radiator. I actually tried what you suggest, but could not see to make it fit with the fans. The tubes would interfere with the fans, making it impossible to have all fans mounted. Push/pull was not possible. I even tried with bigger (thicker) screws, but they could not get a firm hold, actually just making it worse. My solution was to secure it with straps to prevent it from falling on to the hardware inside. Bad solution I know, but it worked - at least until the replacement arrives in a few days I hope. Sorry about the misunderstanding.
