Description

RAZER ↗ HIGH STATIC PRESSURE • 140MM PWM • ARGB DYNAMICS

RAZER Kunai Chroma 140mm PWM Case Fan with Hydraulic Bearing

The Razer Kunai Chroma 140mm is a single high-static-pressure case fan for PC builders who want strong airflow, low noise and Razer Chroma RGB. It spins from 500 to 1600 RPM through a standard 4-pin PWM connection, moves up to 81 CFM, and lights its ring with 22 addressable LEDs.

Fan Dimension140mm x 25mm

Speed ControlPWM (500-1600 RPM)

Bearing TypeHydraulic Bearing

Max AirflowUp to 81 CFM

Static PressureUp to 1.31 mm-H2O

Illumination22 Addressable LEDs (3-Pin ARGB)

🎮 HIGH-PERFORMANCE GAMING & THERMAL STABILITY

Strong Airflow for Long Gaming Sessions

Up to 81 CFM of airflow and 1.31 mm-H2O of static pressure push cool air through case intakes and radiators to keep your CPU and GPU cool under sustained gaming loads.

💼 SILENT CREATOR & STUDIO WORKSTATION

Quiet Operation for Focused Work

Noise stays between 15 and 30 dBA across the 500-1600 RPM range, so PWM fan curves can keep the fan quiet at idle and ramp it up only under heavy render loads.

AERODYNAMIC DESIGN

Optimized Blade Geometry & High Static Pressure

Curved aerodynamic fan blades generate concentrated airflow and high static pressure, driving air through dense liquid cooling radiators and fine dust mesh filters.

DAISY-CHAIN ARCHITECTURE

Connect Up to 8 Fans with PWM & aRGB Control

With Razer's PWM PC Fan Controller and Addressable RGB Controller (both sold separately), up to 8 Kunai fans can be linked to synchronize fan speeds and lighting effects in Razer Synapse.

RAZER CHROMA RGB

Vibrant Razer Chroma RGB Lighting Ecosystem

Powered by the Razer Chroma RGB ecosystem, its 22 addressable LEDs offer 16.8 million colors and lighting effects, controlled from one platform in Razer Synapse.

PWM SPEED CONTROL

PWM Fan Controller Support

The 4-pin PWM connection lets your motherboard, or Razer's PWM fan controller (sold separately), adjust fan speed between 500 and 1600 RPM based on your needs.

Frequently Asked Questions & Store Policies

Can these fans be installed on liquid cooling AIO radiators?

Yes. With up to 1.31 mm-H2O of static pressure, this 140mm fan suits 140mm-based radiators such as 140mm, 280mm and 420mm sizes.

How do I connect and synchronize the ARGB lighting?

Connect the 3-pin ARGB connector to your motherboard's ARGB header or to Razer's Addressable RGB Controller (sold separately). Razer advises daisy-chaining no more than three Kunai fans directly on one motherboard ARGB header.

What is the benefit of 4-pin PWM speed control over 3-pin fans?

4-pin PWM allows your motherboard BIOS and software to dynamically modulate fan speed based on live temperature sensors, maintaining whisper-quiet operation during light tasks and ramping up only when needed.

Are anti-vibration mounting screws included?

Yes. The box includes 4 anti-vibration rubber screws as well as 4 standard Phillips screws.

Are these cooling fans compatible with standard PC cases and AIO radiators?

Yes. It uses standard 140mm mounting hole spacing, so it fits 140mm fan positions in PC cases and 140mm-based radiators (140mm, 280mm and 420mm).

How do I control the PWM speeds and ARGB illumination?

The 4-pin PWM connector plugs into your motherboard CPU/SYS_FAN headers for dynamic thermal control, while the 3-pin ARGB connector works with motherboard lighting software (ASUS Aura, MSI Mystic Light, Gigabyte RGB Fusion) or with Razer's PWM and Addressable RGB controllers (sold separately) in Razer Synapse.

What warranty coverage is included with these cooling fans?

All cooling fans and accessories purchased at AHW Store include official authorized manufacturer warranty with direct local technical support and replacement. Details in our Warranty Policy ↗.

What payment and installment plans are available in Egypt?

We offer cash on delivery, credit cards, and flexible 0% interest installment plans through ValU, Sympl, Forsa, and bank credit cards. See our Payment & Installments Guide ↗.

How fast is shipping and delivery across Egypt?

Orders are delivered within 2 to 7 business days across all Egyptian governorates in reinforced protective armored packaging. See Shipping Policy ↗.

Can AHW Store install and wire these fans in my custom PC build?

Yes! Our certified hardware engineers can install cooling fans, daisy-chain ARGB headers, and calibrate custom thermal RPM fan curves in your build. Explore our Custom PC Builder ↗.
