Packaging and Unboxing

The fan is shipped inside a paperboard packing box in black and orange colors


Let’s check out the fans. They’re 120x120x25mm in size, with 7 translucent blades. The frame is white with a slight blue-white hint, and the center features darkFlash branding.

The blades feature a 3D striped design, with three stripes protruding towards the trailing edge of each blade. This design aims to enhance airflow efficiency while reducing drag. The frame has rounded, sloped corners with anti-vibration pads in white color on each mounting corner. Some corners show scratches, suggesting previous use.

The fan features a stylish striped design on the frame. It has a sturdy build with no arrow symbols for installation guidance. The backside has a unique 6-arm assembly holding the motor and blades but lacks power rating and model details. Made in China, black spots on anti-vibration pads suggest previous use. One arm is wider with an inset for wire routing.

The fans use Rifle bearings with a 30,000-hour lifespan. The motor appears to have 4 poles. The white, flat cables are of sufficient length and come with a 4-pin PWM connector.

WARNING: If silent operation is crucial, be cautious as these fans may produce noticeable noise, especially at full speed (rated 18-30 dBA).

There is a standard 3-pin, 5V ARGB female connector with a flat white color cable. There is also a 3-pin male connector. This allows the daisy-chaining of the fans for a single and synchronized control of the fans.

A-RGB Lighting

Surprisingly, darkFlash says on their website that these fans are compatible with ASUS AURA SYNC, but no other motherboard brand is mentioned. However, since the fans use standard 5V, 3-pin connectors, they will work with any motherboard. We tested them on the GIGABYTE X670E AORUS MASTER using RGB FUSION 2.0 and found them working flawlessly, responding to changes in light mode.

PRO TIP: Customize fan curves for optimal performance, balancing cooling efficiency and noise levels based on your preferences.

Here are a few pictures of these fans in action:


The following test bench is used for thermal performance testing:

I tested the cooler’s thermal performance using a 30-minute run of Cinebench R23, comparing the DeepCool FK120 fans with the darkFlash CX6 RGB White fans. It’s important to note that each stress test run may not have the same result due to factors like mounting pressure, thermal paste application, ambient temperature, and silicon differences among chips. Providing the testing methodology and specifics is crucial.


With an ambient temperature of around 18 to 20°C, there’s a difference of approximately 1.3°C between the DeepCool fans and the dark flash CX6 RGB White fans. This shows that the darkFlash fans performed well, considering the DeepCool FK120 is designed for high static pressure with a rating of 2000 RPM, 3.27 mm H₂O static pressure, and 85.85 CFM airflow.

The fans at 100% of their speed were doing approximately 51 dB(A) at an ambient of 32 dBA. The DeepCool FK120s were doing 50 dBA.

Should You Buy It?

Buy It If

You are on a Budget: The darkFlash CX6 AURORA SPECTRUM RGB White fans offer a budget-friendly option for users looking to enhance case ventilation without breaking the bank.

You Prioritize Aesthetics: If customizable RGB lighting is a key factor, these fans with A-RGB illumination in cool colors like White, Black, Pink, and Neo Mint might be the perfect fit for your visually appealing setup.

You Want Compatible RGB Lighting: If you own an ASUS motherboard with AURA SYNC or any other motherboard with standard 5V, 3-pin connectors, these fans will seamlessly integrate into your RGB ecosystem.

Don’t Buy It If

You Require Whisper-Quiet Operation: These fans may not be ideal if you prioritize an extremely quiet operation, especially at full speed, as they can produce noticeable noise (rated 18-30 dBA).

You Need Specific Brand Compatibility: While the fans claim compatibility with ASUS AURA SYNC, the limited information may pose uncertainty if you prefer other motherboard brands for RGB control.

Final Words

The darkFlash CX6 AURORA SPECTRUM RGB White fans are budget-friendly and stylish in different colors. They come in 120mm size, offering a speed range of 800 to 2000 RPM, airflow of 55.29 CFM, and static pressure of 1.63 mm H₂O. They aim to enhance airflow with 7 translucent blades and a 3D stripe design. These A-RGB fans have standard connectors compatible with most motherboards. In tests against DeepCool FK120 fans, the CX6 fans performed well, trailing by 1.3°C. They are suitable for case ventilation, but full-speed operation may result in high noise, so a custom fan curve is recommended.
