Yeah it comes down to what's important to each of us personally, I'm not really bothered about getting the very last MHZ out of everything, and absolute silence isn't a must have for you. Each to their own and, viv la difference
These sinks look crammed in but probably could be mounted to spreader plates, then all mounted to one block above them. Probably require unsoldering them from the mobo to get at the screws, so I'd mount them to a custom block and lengthen the pins like my PSU. Doesn't look simple whatever, and could involve motherboard death trying it.
