Cooling accessory Noctua NA-SRC7 – black, 111×29×150 mm, 57 g

The NA-SRC7 is a fan accessory set that contains three fully sleeved NA-RC7 Low Noise Adaptors (LNA) designed for Noctua 4-pin PWM fans. When connected between a fan and the power source, these adaptors lower fan speed and reduce noise emission, making them suitable for systems where quieter operation is required. The adaptors are compatible with Noctua redux edition fans and other 4-pin PWM models; refer to manufacturer speed tables for exact rpm reductions.

Advantages

The NA-SRC7 provides a simple hardware solution to reduce fan noise without changing fan profiles in software. Fully sleeved cables improve cable routing and durability while preserving PWM control on supporting motherboards. The pack of three adaptors allows multiple fans to be slowed simultaneously for a consistent acoustic profile.

Suitable for

• Reducing noise in desktop PCs and workstations
• Slowing Noctua redux and other 4-pin PWM fans
• Systems where lower acoustic output is preferred over maximum airflow

Key specifications

• Type: Low Noise Adaptor (LNA) set for 4-pin PWM fans
• Quantity: 3 adaptors
• Compatibility: Noctua 4-pin PWM fans (including redux edition) and other 4-pin PWM fans
• Colour: Black
• Weight (pack): 0.057 kg

How to use

Disconnect the fan’s 4-pin connector from the motherboard or controller and plug the NA-RC7 adaptor between the fan and the power source so that the adaptor’s connectors align with the fan header. After installation, power on the system; the adaptor will pass PWM signals while lowering the fan’s voltage to achieve reduced speed and noise. Check Noctua’s speed tables or measure rpm to confirm the achieved reduction.

Recommendations

Use the NA-SRC7 where prioritized silence is more important than maximum cooling performance. Ensure your system’s cooling remains adequate after slowing fans, especially under heavy load; monitor temperatures when first applying the adaptors.
