Corsair Air Series SP120 Quiet Edition Fans
Moving into light blue and black packaging now for the Quiet Edition of the SP120 helps you discern from the two parts of the series. Surprisingly, the static pressure isn't listed right on the front with the RPM and 23 dBA noise rating.
If you look at the CPU cooler you can see the SP120 mounted to it in the build image while the bottom shows the same three specifications as the front does.
Splitting the packaging open again shows the SP120 insides the chassis on the AIO radiator with three features of the fan in the images that run across the bottom. On the right you get a look at an oddly plain seven blade fan with really wide blades.
On the back Corsair tells you that the wide blades are what brings in the higher levels of static pressure and where you may want to use them. Even though this is a quiet solution, the SP120 QE has a higher static pressure rating that all of the AF120 and AF140 fans.
To simplify things I only grabbed one of the hardware kits. Here you get the three color rings, the paperwork and the bag of screws with the low voltage adapter in it. You do get two sets like this in this twin pack.
Once I removed both fans I realized I have two different designs. Connecting and running them, I verified the RPMs and the flow seemed on point in the testing. Other than the hub difference around the hydraulic bearing in the SP series and the lack of stickers, I can't really say what happened here.
The fan with the blue ring on it even lacks the manufacturer sticker on the fan frame. As for the other fan, it corresponds to the model number on the box.
Even on this side of the fan with the individual numbers applied to the fan frames, both numbers are a match. I am assuming there was either a last minute design change to the ribbed hub or I got a test fan that wasn't meant to be in the retail packaging.
