Medium-speed loses to Noctuas (larf). Also note the reviewer's (Vapor's) comment on it:

1) Okay, who didn't see the Slip Steam's demise coming? I know I've been harping on it for the longest time...but even this surprised me.

1a) When first testing this fan for the Fan Filter Comparison I did, I noticed it was actually performing okay on the radiator. Airflow numbers weren't horrendous like I anticipated. The 1900RPM "SH" actually had similar airflow loss to the 1900RPM S-Flex G. I was kinda flabbergasted. Then I turned off the music, turned off the A/C, turned off the TV, turned off the loud-as-sin Xbox 360, turned off the dogs and turned off the gf and I noticed something--the Slip Streams were getting significantly louder on a radiator. Well beyond the point of turbulence noise...it was like the fan was increasing its RPM...significantly. Now I haven't tested THAT (RPM sensors I've learned to not trust, thanks ASUS, Intel, Abit, and DFI), but I figured I might as well test the noise it makes on a radiator...then I realized if I was going to be testing the noise it made on a radiator, I'd have to test all fans on a radiator for noise. No longer could I assume the difference would be negligible....thanks Scythe.

b) So I began testing noise on a radiator set up and....wow...my ears were right, the thing makes a ton of new and extra noise on a radiator. Whereas the Yate Loon and S-Flex basically were unchanged on the radiator, the Slip Stream acted like a completely different fan--a fan out of the 1200RPM class.

Martin showed a similar trend in his tests.
