The high airflow AF140 has more (11) and narrow blades, capable of creating higher airflow when there is no restriction, while the SP140 has fewer (7) and wider blades, allowing it to create higher pressure and overcome airflow obstacles.Ī mere look on the non-LED version of the fans is enough to reveal that they are higher performance designs than the LED versions. The AF140 and the SP140 side-by-side look almost identical, with the exception of the fan's blades. We received the white version of the fans but they are also available in blue, red, green and purple. There are four LED lights installed on the frame, in parallel with the plastic engine support bars. The wiring and the connector, as well as the provided screws, are all black. The LED versions of the AF140 and the SP140 both have black plastic frames with narrowed bezels and semi-transparent blades with a "frost" texture. For example, the AF140 Quiet Edition and the LED version (the AF140 LED White Quiet Edition) do share a similar product number but the non-LED version ends up having significantly better performance specifications. We will examine these differences thoroughly, but take care not to confuse the standard with the LED versions of each fan. We should start by immediately mentioning that the LED fan versions are not of equal design and performance as the standard versions. This could lead up to 16 different combinations (colors of LED not withstanding), although Corsair picks and chooses so only a few of these to produce. Theoretically Corsair's offerings end up with many degrees of freedom - select AF or SP, select 120mm or 140mm, then select Performance or Quiet, the LED or no LED. The SP120 Quiet Edition 120mm fan (High Static Pressure).The AF120 Quiet Edition 120mm fan (High Airflow).The SP120 Performance Edition 120mm fan (High Static Pressure).The AF120 Performance Edition 120mm fan (High Airflow).The SP140 LED White 140mm fan (High Static Pressure).The AF140 LED White Quiet Edition 140mm fan (High Airflow).Corsair supplied us with six different fan products, which are: Corsair is our company of choice for our first review, as they offer a variety of cooling fans wide enough and designed for different applications, permitting us to easily showcase the difference between fan designs. IntroductionĪs this is our first proper fan review, our primary focus is to showcase and explain the differences between different kinds of fans, as well as to begin the composing of a performance database. Today we are looking at several of Corsair's high-end fan offerings in the 120mm and 140mm size from their SP (Static Pressure), AF (High Airflow) and LED ranges. Through our fan reviews, we will attempt to simplify some of these parameters and assist you with making a proper selection. Even if someone knows the exact performance curve of a fan and can make an educated assessment regarding the airflow impedance, parameters such as the quality and noise come into play as well. Both the selection and the testing of a fan can be a rather complicated matter.
