Saying the A15 is "better" is very subjective. Quieter at 1200rpm yes, but what would TY-140 be at 1200rpm vs 21dBA at 1300rpm. My guess is the same or less... and you are going to be hard pressed to hear the difference between 19.2 and 21dBA. TY-143 is 4 times as loud moving twice as much air and spinning more than twice as fast. You can compare them all at 1200rpm and my guess is they will be very similar. But to compare them at full speed is like comparing a bitter decorative crab apple to a sweet golden delicious apple.. Both are apples and not much else in common.
NF-A15 = 67.9cfm @ 1200rpm & 19.2dBA
TY-140 = 73.4cfm @ 1300rpm & 21dBA
TY-143 = 130cfm @ 2500rpm & 45dBA
And of course this is using manufacturer specifications so again. I suspect they are relatively close to real, but...
Here's a link to a video review of H100, SA SB-E & SA SB-E Extremehttp://www.youtube.com/watch?v=q6xrsuPwDbo
jump in to 3:40 for results
I found it very interesting how much better the SA SB-E does when it's running fans similar to what H100 has.
Similar results have been found running high cfm / high speed fans on other big twin towers as well.
i7 3820 @4.75GHz
Temperature is delta.
H100 . . . . . . . . 41c 2500rpm. . . . . . . . 55dBA 2
SA SB-E . . . . . . 42c 1100rpm & 1300rpm 38dBA TY-150 & TY-141
SA SB-E Extreme 34c 2500rpm. . . . . . . . 56dBA 2x TY-143
Here's a link to a bunch of sound bites of different coolers idle and full speed.
Just remember that the SA SB-E and SA SB-E Extreme sound the same from idle to 1300rpm. It is only above 1300rpm that the SA SB-E Extreme gets louder.Edited by doyll - 3/22/13 at 2:30am
