the TEV valves arn't made for such a small amount of watts that these cpu are putting out so dont go that route, capillarys are much better if you dont need to take away that many watts. A condensor that fits 2 120mm fans will do just fine, see if you can get it in more than one layer as that will be even better and could help your temps a tad. You are on the wrong side of the compressor for liquid slagging to take place, and that only happens when you overcharge the unit.
