I guess I do. I was trying to find reasons NOT to buy them. Because the Eloops IMO just Look fantastic. But a good looking fan isn't any Good if it doesn't blow. I was looking at Cooling Techniques Pressure curves against ML120s and earlier Vardars. And they all seem to pull quite well when presented with minimal restriction. But after about 2mm/h2o the Eloops drop off quite quickly and don't scale much above 2.5mm. But the ML120s scale beyond 3mms.A whole centimeter is quite a bit of space. I'm sure that's enough to be able to use the eLoops in push and pull. They are quite capable fans, and it seems the added cost over Arctic isn't a concern for you. Sounds like you have your answer!
I do have a question. How much resistance would a "typical" rad like a medium thickness PE360 rad cause?
