 You know who doesn't get enough credit for their fans? Silverstone. This is the AP123. I mean honestly, these guys probably spend more money and more energy engineering their fans than almost anyone else out there. I mean, everyone and their dog manufactures a fan. Where basically they're taking some OEM fan made by Yate Loon or whoever else, and they're slapping a label on it, they're having it made to a spec with some LEDs or whatever else. Silverstone actually engineers fans. The AP123 is an evolutionary step forward in their Air Penetrator series, although it seems to be not called Air Penetrator anywhere, but I'm assuming the AP is because it's sort of similar in terms of the technology. And the original Air Penetrator was designed for focused airflow. And you can see that this one has the same airflow focused channels on the back of it that the old one did. The key difference between this one and the old Air Penetrator, I actually use AP121s, the original Air Penetrators, on my radiator in my system because they undervolt extremely well, they're very quiet, and the focused airflow allows them to draw air through the radiator and then push it out the back of my case, because there's a bit of a dead zone between the outer, the grill on the other side and the other side of the fan. So it's cool because it makes the airflow not just through my radiator more effective, but also the airflow through my case more effective. So with the AP123, what Silverstone has done, so first of all, so general specs, blue UV blades, black frame, got it? That's a nice UV blue too. On the old AP121s, it was kind of a translucent one, this should look quite striking. 5 volt DC start voltage, outstanding. If you're using DC control for your fans, it's nice that they'll start at such a low voltage. That means you can even, instead of using undervolting adapters or whatever else, you can make your own adapters just by running the fan off the 7 and 12 volt, instead of a 12 and ground, so you have a 5 volt difference. Not that I necessarily recommend making your own electric adapters, but whatever. Up to 1500 RPM, although it'll go significantly lower than that if you undervolt it. Lifetime of 50,000 hours. Excuse me, sorry. Fairly solid static pressure rating, and whatever. So taking air channeling fan to another level, I wish they'd had someone proofread this. Industry leading air channeling fan, and the AP certainly was when it launched, so I'm sure they're sort of keeping this going. Integrated air channeling grill doubles as a fan guard to reduce the overall size, which is nice. And let's finally get into what makes this fan super special. Check this out. See this right here. What Silverstone discovered is that in order to reduce the noise, you want to reduce the patterned-ness. You want to break up the... In order to reduce sort of humming noises and any kind of vibration, you want to break things up a little bit. You want things to be different. So they have three different sizes of fan blades on this fan. I'm going to let you guys look for it. Okay. Broad, three of those. Medium, three of those. And small. This makes the fan according to Silverstone, so you can see they're also completely different shapes. So this looks more like the blade on the original AP. This looks more like a standard fan blade, but with a bit of a curvature up at the end here. And this one is quite curved at the end. So this is supposed to make the fan better optimized for silence and performance, while just sort of generally also being awesome in directing airflow through your case. I mean, when it comes to directed airflow, it's useful for a number of things. So I would use directed airflow fans wherever you need to not only draw air through something, but also towards something. So for example, a great place to use it would be if you have a case, where I'm going to stand this way, if you have a case where the front intake is here, and then you've got your hard drive cages, and then you've got more fan mounts, like something like a Corsair C70, I would mount something like this on the other side of those cages, because now I have a pressure optimized fan to draw air through the restrictive cages, then I have channeled airflow going directly to my graphics cards. That's where the application of a fan like this is. They are including a nice high quality sleeving, so even though the wires themselves are colored, you can't actually see the colors through the sleeving at all, which is great. There we go. And they include both screws and noise isolating, vibration isolating rubber grommets to mount the fan to your case. So that pretty much wraps it up.
