I'm thinking of possibly making a single rad loop for my 920 in the future, but have absolutely no room for a pump. My idea was to get something like http://www.performance-pcs.com/catal...ducts_id=22697 (I do have 1 open bay) I just don't know if 200l/hr is enough to cool it sufficiently. The description says "perfect for a second loop" which is why I'm questioning it for cpu usage. Also because my case uses 140mm fans (only has 140mm mounting holes) would it be better to get a Black Ice GTX 140mm or a Feser 120mm? I could rig the 120mm to fit if it would perform better. The 140mm is bigger but the 120 is thicker so again I'm a little confused.
