Lol, the issue is more that recently there has been an inlux into the industry of HIGH airflow cases with multiple 120mm fans, huge side and top mounted etc... the more "traditional" single and dual fans move air just fine, as long as that air is coming in and going out the temp will be relatively managed. We've just become so accustomed to these newer cases with massive airflow that the more traditional rigs are becoming the abnormal. Unless you're looking to push a big OC these fans are just fine.
