CORSAIR AirGuide Technology Explained

With the launch of our 4000 Series and 5000 Series cases, many of you may have noticed the addition of new case fans with something we call CORSAIR AirGuide Technology. Fans with CORSAIR AirGuide Technology, such as the newly released SP RGB ELITE series, feature anti-vortex vanes which help to channel concentrated airflow for improved cooling performance for your components.

Case Fans… How Do They Work?

Before jumping further into what makes AirGuide compelling for cooling, let’s review the purpose of a standard case fan. A typical case fan is designed to pull cold air from the intakes of your computer or push hot air out as exhaust. When installed properly, case fans will promote the exchange of heat from your components/heatsinks/radiators and the air to allow your components to cool off.

When installed in a typical mid-tower case, the airflow of a standard case fan will look something like this:

Airflow from a standard case fan.

The air pulled through a standard case fan immediately spreads out into the case and while the air does have a general velocity away from the fan, it’ll quickly dissipate the further away from the fan blade it travels.

When installed in a typical mid-tower case, the airflow of a fan equipped with CORSAIR AirGuide Technology will look something like this:

Airflow from a case fan equipped with CORSAIR AirGuide Technology.

Comparing these two example, you’ll notice that the airflow from an AirGuide fan is much more concentrated, reaching further into the case before eventually dissipating.

What about Performance?

If we had to put it simply, more fresh air = generally better temperatures. You can brute force this by installing as many fans as your chassis will take and cranking them up to their highest setting, but picking the right fan for the job will result in much better performance and a quieter system.

We tested two identical systems using only SP RGB ELITE fans in one and SP RGB PRO fans in the other:

As you can see from the graph, upgrading to higher airflow SP RGB ELITE fans on our test system resulted in improved CPU temperatures on our air cooled system!

Another notable benefit of AirGuide fans is higher static pressure when compared to similar case fans without anti-vortex vanes.

For example, here’s some data from a test bench where we compared the performance of the AirGuide Technology-equipped SP RGB ELITE fans to our SP RGB PRO fans. We measured coolant temperatures on a H150i ELITE CAPELLIX cooler, controlling for ambient temperature, CPU clock speed, voltage, pump profile, and fan RPM.

At the same speed of 1000 RPM, SP RGB ELITE fans demonstrate a noticeable improvement in temperature control over the older SP PRO fans when used on the radiator of an all-in-one liquid CPU cooler.


Many may think that a fan is a fan as long as it spins and pushes air, but fan performance can’t be just pinned to how fast you can spin the blades. Seemingly small improvements like adding anti-vortex vanes to the rear of a fan like we did on our SP RGB ELITE can help give your system more thermal headroom, allowing you to keep your temperatures low and your framerates high.

CORSAIR Vengeance Gaming PCs with advanced graphics technologies like real-time ray tracing and DLSS AI up-scaling powered by NVIDIA RTX 30-Series graphics give you all the performance you need to play the latest AAA titles in full fidelity.

CORSAIR Lab video explaining benefits of ray tracing and DLSS on systems powered by NVIDIA RTX.

First, let’s briefly define and talk about what RTX Ray Tracing and DLSS are before we jump into why the CORSAIR Vengeance a7200 Gaming PC is a solid choice for modern titles.

Ray tracing on supported titles can result in more realistic shadows, reflections, and lighting.
A game with ray tracing can have more realistic shadows, reflections, and lighting.

RTX is NVIDIA’s implementation of real-time raytracing using dedicated RT cores baked into the GPU to do highly complex calculations for lighting and reflections. Allowing in-game environments to be even more immersive.

DLSS helps to lighten the load on your graphics card, resulting in a sharp increase in FPS when enabled.
DLSS can result in sharper, high resolution images without putting a huge load on your graphics card.

While ray-traced lighting and shadows provide an easy to spot visual upgrade to games, DLSS (deep learning super sampling) is where the real magic is, boosting FPS by rendering a supported game at a lower resolution that is then upscaled using AI to produce frames at awesome quality. 

Also note that turning raytracing on by itself is not recommended as current hardware are still struggling to handle such workloads without the help of DLSS. Without making this blog too long about how DLSS and raytracing work together, here’s a quick rundown.

  1. DLSS works on a game-by-game basis, using a model put together with machine learning on an NVIDIA supercomputer comparing aliased, low resolution frames from a game to “perfect” frame renders at a higher resolution.
  2. With all this information baked into the DLSS model, a game with DLSS will replicate these perfect high-res frames to produce cleaner, high resolution frames even though the game itself renders at a lower resolution on your machine.
  3. This helps to free up system resources for your game which results in higher framerates. Thus, allowing you a more enjoyable experience.
Inside of a CORSAIR Vengeance Gaming PC

These technologies are game changing and when paired with CORSAIR components in a system like the Vengeance i7200 or a7200, the RTX 30-series graphics cards run at peak performance with all the power and cooling they need to drive the latest AAA titles on all the “pretty settings”.

Special edition Cyberpunk 2077 RTX 2080 Ti graphics card.

Cyberpunk 2077 with RTX on features ray-traced shadows, reflections, global illumination, diffuse illumination, and ambient occlusion for a more vibrant, life-like Night City, making this a game that benefits greatly from NVIDIA DLSS. To demonstrate, we’ve set up a quick test on our Vengeance A7200, setting everything including Ray Tracing to ULTRA at 1440p, but keeping DLSS off. With those settings we managed 39.52 FPS on average. Testing again with DLSS set to quality mode, we hit an average FPS of 60.10, resulting in a much smoother experience while maintaining excellent quality.

Call of Duty Black Ops Cold War supports ray traced lighting and DLSS.

And to further drive the benefits of DLSS, we did a similar test with Call of Duty: Black Ops Cold War, this time cranking the resolution up to 4K with all settings including ray tracing set to maximum. Without DLSS, our average FPS was a respectable 55.86 frames per second. However, switching on DLSS Performance mode gave us a drastic improvement, increasing our average FPS to 77.55 with a barely noticeable difference in quality.

And there you have it, CORSAIR Vengeance Gaming PCs and NVIDIA RTX graphics are the perfect pairing for your next upgrade, delivering gorgeous visuals and silky smooth gameplay!

How to 3D Print Blank Pump Caps

To get caps to 3D print, download the 3D files for the CORSAIR ELITE CAPELLIX CPU liquid cooler pump cap and take them to a 3D printing site or print on your own 3D/resin printer if you happen to have one. If you want a completely transparent blank pump cap, use a clear resin as the printing material and if you’re not concerned about transparency, you can print with a standard 3D printer using PLA or ABS filaments in very light colors which would allow the RGB lighting to shine through.

Making Your Own Pump Cap Decals

Use this template to get the dimensions of the area you have to work with for a custom design.
While a vinyl decal would produce the best results, you can try out a design by making a paper decal and sandwiching it between a blank, clear pump cap and the light diffusor of the pump head. Print out the design you’d like on one side of your paper, then mirror it and print it again on the other side to reduce the amount of light bleeding through the print.
If you have access to a vinyl cutter or intend on hand cutting a design, make sure that you reverse the image before cutting so that it’ll be oriented the correct way when applied to the bottom of the pump cap, especially if using vinyl with an adhesive side.
Once you’ve made your design, make sure to trim it down to size for the pump cap and install!

Blanking a Stock Pump Cap

If you don’t have access to a 3D printer or are unable to get a 3D printed pump cap made, you can mod one of the stock ELITE CAPELLIX pump caps! Put the stock pump cap down on a soft material such as a towel or paper towel to avoid scratching up the front of the pump cap. Use 180 to 220 grit sandpaper, and sand with moderate force repeatedly in a single direction, going in a cross pattern will scuff up the side of the pump cap you’re sanding and will likely make the pump cap cloudy (we would recommend wet sanding if possible). Repeat the sanding until the decals wear away. Rinse all dust from the pump cap and wipe dry with a paper towel.
Badsad has additional tips and tricks and links to 3D printing resources, options for decal paper, and more in their forum post.
