My system is doing OK with my FOP 32-1 and the stock YS-Tech Fan. Like you they aren't great, but they aren't that bad either. I think one of the golden gate (gladiator) type HSF will be my next purchase in that respect. It's not like the FOP32 can't take what I am giving it right now, but I can't take it over where I am without more cooling and I am sure this thing will go into the 1.4 range. I am tempted to just see how a Delta fan will make a difference on the unit if any. When I order my gladiator (or whatever) from that SVC place people have been ordering from, I will get it with the Delta fan just so I can experience the annoyance first hand! ;-)
