-extremely quiet
-the best directional airflow fan on the market
Weaknesses:
-not a lot of CFM
Summary:
At 1500rpm and with it's large blades, this fan is super quiet. I have mine mounted inside the case pointing right at my GPUs and the temps dropped dramatically compared to a regular fan that was there before. There's youtube vids showing the airflow... most fans shoot air outwards but these fans target the air in a straight cylinder.
