The Xigmatek XAF Series of fans is a brand new line of fans to come from Xigmatek, focusing on quiet operation with high airflow. These fans come with a 1 year warranty and range in price from $23.99 to $24.99 plus $2.99 for shipping & handling. While these are new products to Xigmatek's fan line up, we at Legit Reviews have actually seen them before on the NZXT Havik 140mm Tower Cooler. Let's just say, that cooler had some disappointing cooling performance in some regards, but perhaps that was due to fan choice and not the actual heatsink design? We'll be reviewing that topic later once we get to performance, but as it's obvious from the blade design of these fans, we do not have a design intended to produce a lot of static pressure. Xigmatek themselves is not new to the Heatsink market, and also uses these fans on their Prime SD1484 Tower Cooler.
