I agree with DT. Those Swiftechs are solid. The smallest clearance model sports 11mm spacing between mount points.
I have those Phobya connectors, but I don't see an issue with them unless you pull them too far apart. One failure point more though.
I think DT's setup has more pressure than average Joe's so he'd be better off with the sturdiest he can find. That silicone sealant wouldn't be bad idea either.

Oh and that koolance thingy is rubbish. The price is ridiculous and it doesn't have even nearly enough cooling power for rjk's needs.
