Martinm, glad to see you did a reveiw of the Treibwerks as well.

I have the LS models (1250) rpm..and one of the things I did notice or would appear to hold true, since I dont have the technical tools to test this theory with...

Im running mine as a pull only configuration, inside my HAF case 2x ek coolstreams ( yes I have 2 240 rads internally in a HAF 932 case) ..anyways it seems to me that my temps are a little bit lower, and im thinking from going by my initial loop setup with them in push* that they are a little quieter..... wonder if you have your testbed still set up to see if there is actually any differance with them in pull... thanx..

and thanx for all the time and testing you do for us to bring these kind of numbers for us to use when setting up our fans for whatever purpose they are used.
