I am wondering which Scythe case fan is better between the following two series:
Slip Stream 120mm Case Fanhttp://www.scythe-usa.com/product/acc/0 ... etail.html
Slip Stream Kazemaru2 140mm case fan (120mm mounting holes)http://www.scythe-usa.com/product/acc/1 ... etail.html
If I am understanding the specs right, those 140mm fans are similar or not as good as the 120mm fans... am I right? (I was expecting same airflow with less noise from 140mm fan vs 120mm)
Comparing the 1200 rpm models: (the ones Im most interested in)
120mm fan produces 24.00 dBA and 68.54CFM
140mm fan produces 23.20 dBA and 65.2CFM
Comparing 1700/1900 rpm:
120mm @ 1,900 rpm = 37.00 dBA and 110.31CFM
140mm @ 1,700 rpm = 36.40 dBA and 92.4CFM (same noise but a lot less airflow = a lot worse than the 120mm when you'd expect a 140mm to perform better)
and the slower 140mm fans produce a bit more airflow with significantly more noise....
Is there something I am missing in all these specs, and is there any reason/advantage to get the 140mm fan over the 120mm? (both use the same 120mm mounting holes).
EDIT: I've taken a look at the newer Glide Stream series, and it seems to have similar results... the 120mm fans push more air quieter than the 140mm fans, and do so with higher static pressure. Note that Im going by the test results, not by the manufacturer stated specs. It seems there is absolutely no reason to get 140mm Scythe case fans... they perform poorer than their 120mm counterparts.http://www.coolingtechnique.com/recensioni/74/1136.html
