Seriously though... that's odd. Maybe the turbulence pattern is just more defined with that one? Have you tried adding any kind of air-straighteners?
I tried hand-ducting (putting my hands around it to make it a closed frame)....didn't help. May be turbulence....but then I'd expect the radiator tests to be 'normal' and they weren't. The spinning turbulence is A LOT weaker than the Delta's. Deltas get negative CFM readings in push...heh, this one got positive readings, and up near ~15CFM (for a fan that spins the wrong way, that's really high, means very little turbulence).

I don't want to spend a lot of time on the fan as it makes weird vibrational noises when mounted (even with silicone 'screws')....anybody who has one knows the weird way they mount the fan onto the frame....IMO, it's bogus since in my hands, it's a nearly-normal sounding fan...but on a case, it isn't at all. I've tried just placing it on the case, a loose mount, a TIGHT mount and silicone screws...all have this weird vibration noise.
