For years, PC airflow has followed a familiar formula: cool air enters from the front, passes through the system, and warm air leaves through the rear or top.

But modern PC hardware is changing that equation.

A recent CFD airflow simulation highlighted how adding 

 can significantly change the way heat moves around the GPU and CPU cooler. The results also raise a bigger question for PC case design:

Could the space underneath the case become an important part of the cooling system?

In the simulation reported by HKEPC, a traditional front-intake configuration allowed heat from the graphics card to rise and recirculate around the CPU cooler.

The reported simulation started with room-temperature air at 

. As heat accumulated, the air entering the CPU tower cooler reached approximately 

With bottom intake added, cooler air was introduced beneath the graphics card and helped move GPU heat toward the exhaust path. In that specific simulation, the air entering the CPU cooler remained close to 

 compared with the conventional configuration. 

This does not mean that every PC will see the same temperature difference. Case design, hardware, fan speed, GPU layout, and room temperature can all change the result.

But the simulation demonstrates an important idea:

Where cool air enters the system can matter as much as how much air enters.

The Bottom of the Case Is Becoming Part of the Airflow Path

As graphics cards become larger and produce more heat, delivering cooler air directly to the lower part of the system becomes increasingly relevant.

This changes how we think about the bottom of a PC case.

Traditionally, the area beneath the chassis mainly provided structural support and clearance.

But if bottom intake becomes a larger part of modern airflow design, case manufacturers may need to consider:

In other words, the base of the case can become a functional part of the cooling design.

By creating physical space between the main chassis and the surface below it, a floating base can give bottom ventilation more room to draw in air.

Its floating extended base is designed to channel air from the 

 into the chassis, making airflow part of the structure rather than treating the base as purely decorative. The ATX version also uses a side fan mount angled an additional 

 to create a more focused intake path around the graphics card.

Floating PC cases are visually distinctive, especially in showcase-style builds.

But their potential value may go beyond appearance.

If future PC cooling continues to focus more heavily on 

bottom intake, GPU-focused airflow, and multidirectional ventilation

, the space beneath the chassis could become increasingly important.

That does not mean every future PC case will use a floating design.

But it suggests that one of today's visual design trends may also point toward a more functional approach to airflow.

The floating base may look like a design statement today.

In the future, it could become part of how PC cases breathe.

Bottom Intake Is Getting More Attention

In the simulation reported by HKEPC, a traditional front-intake configuration allowed heat from the graphics card to rise and recirculate around the CPU cooler.

The reported simulation started with room-temperature air at 22°C. As heat accumulated, the air entering the CPU tower cooler reached approximately 35°C.

With bottom intake added, cooler air was introduced beneath the graphics card and helped move GPU heat toward the exhaust path. In that specific simulation, the air entering the CPU cooler remained close to 22°C—a difference of up to 13°C compared with the conventional configuration. 

This does not mean that every PC will see the same temperature difference. Case design, hardware, fan speed, GPU layout, and room temperature can all change the result.

Traditionally, the area beneath the chassis mainly provided structural support and clearance.

But if bottom intake becomes a larger part of modern airflow design, case manufacturers may need to consider:





More space underneath the chassis



Larger bottom ventilation areas



Less obstruction around intake openings



Better access to fresh air around the GPU



Combined bottom and side intake paths

In other words, the base of the case can become a functional part of the cooling design.

Why Floating-Base Designs Make Sense

This is where floating-base case designs become interesting.

By creating physical space between the main chassis and the surface below it, a floating base can give bottom ventilation more room to draw in air.

The darkFlash Floatron F1 is one example of this approach.

Its floating extended base is designed to channel air from the bottom and sides into the chassis, making airflow part of the structure rather than treating the base as purely decorative. The ATX version also uses a side fan mount angled an additional 8° toward the GPU to create a more focused intake path around the graphics card.







From Visual Design to Functional Design

Recent CFD simulations highlight the potential of bottom intake for modern PC cooling. Here’s why floating-base designs could play a larger role in future case airflow.

Floating-Base Design Is Redefining PC Case Airflo

darkFlash is marking a significant milestone at CES 2026 with its first large-scale exhibition booth. Centered around a distinctive "Space" theme, the immersive display showcases a comprehensive ecosystem of PC components tailored specifically for the US market.

From award-winning chassis designs to an expanded lineup of thermal solutions and peripherals, darkFlash is demonstrating its commitment to providing versatile and innovative options for PC builders.

Innovation Takes Center Stage: The FLOATRON F1

Leading the showcase is the FLOATRON F1, recognized as a CES 2026 Innovation Awards Honoree. Building on this accolade, darkFlash is introducing the highly anticipated ATX version of the chassis this year.

The new model enhances the signature floating structure with an integrated LED strip at the base, creating a suspended visual effect that deepens the immersive experience for users.

The F1’s design is defined by its functionality. The Floating Extended Base not only creates a unique aesthetic but is engineered for superior airflow, channeling air from the bottom and sides into a seamless multidirectional flow to keep the system cool and steady.

Beyond performance, the floating base doubles as a multi-functional display platform. It serves as a customizable stage where users can showcase figures or lighting effects, blending cooling performance with creative expression. Combined with quick-release side panels and a smart interior layout, the F1 is designed to make upgrades intuitive and every inch of the build count.

Following the success of the DY470 in 2024—which captivated users with its diamond-cut exterior, panoramic three-sided glass, and dual-chamber layout, darkFlash is expanding the series with the DY460, the primary focus for 2025.

While retaining the celebrated aesthetic DNA of its predecessor, the DY460 adopts a vertical layout with a top-and-bottom chamber design. This shift offers a more compact footprint, significantly saving desk space. By offering both the wide-body DY470 and the space-efficient DY460, darkFlash ensures that consumers can enjoy the series' distinct visual style while choosing the form factor that best fits their setup.

Visualizing Performance: Cooling and Chassis Diversity

In the realm of thermal solutions, darkFlash is highlighting the UV360 AIO liquid cooler. This model features a detachable, magnetic curved screen on the pump block, allowing users to freely adjust the viewing angle and enjoy the unique visual impact of a curved display.

Also on display is the Explore Series, featuring the DE360 AIO and E400 air cooler, which served as key highlights during Computex 2025.

The chassis lineup is further diversified with models catering to various aesthetic preferences. The U1 introduces a double-curved glass design, ensuring an omni-directional view of the internal components from any angle. The DS900 series offers specialized variations, including the glass-focused DS900G, the wood-accented DS900W for a warmer aesthetic, and the DS950V, which integrates a customizable screen into the front panel.

Expanding the Ecosystem: Peripherals and Components

Rounding out the exhibition, darkFlash is showcasing a robust range of peripherals that have garnered significant attention at the show. The keyboard lineup includes the popular GD Series, the pixel-screen equipped PXD Series, and new models featuring magnetic switches and premium aluminum alloy construction.

To support these builds, the booth also features the latest in power and airflow, including the G24 and INF34 daisy-chain fans for simplified cable management, alongside a variety of power supply units designed for the mainstream market.
