I remember asking you about coolers long time ago. Basically since then I've used what you've recommended - a pair of NH-U12S - officially they are incompatible with MS73, but in reality they fit, however putting fans back on the cooler is harder than it should be (you can't put your fingers between the coolers, so you need to push the bracket in and help yourself with a screwdriver if needed).they work. but cooling can be an issue if FANs are in a row.
