Razer PWM Fan Controller 8 Headers
The Razer RZ34-02140700-R3M1 is an internal fan controller designed to manage up to eight PWM fans from a single USB 2.0 header. It draws power through a SATA connector and connects to the motherboard via a micro-USB to internal USB header cable. The unit measures 100.00 x 70.00 x 18.65 mm and includes cables of 530 mm and 500 mm length. It provides centralised speed control without ARGB lighting management.
Builders needing eight-channel PWM fan control via
This controller suits PC builders who want software-managed fan curves for up to eight 4-pin PWM fans using a single internal USB 2.0 9-pin header. It is not suited for systems lacking a spare USB 2.0 header or a SATA power connection. Users requiring ARGB or addressable RGB control should look elsewhere, as this device handles fan speed only. It also does not support voltage-controlled 3-pin fans in PWM mode.
Eight PWM channels with SATA power delivery
The eight 4-pin PWM headers allow simultaneous control of multiple case or radiator fans, providing headroom for high-airflow builds with several fans. Each header supports standard PWM signalling for precise speed adjustment. The SATA power cable delivers sufficient current for typical fan arrays, though total draw depends on the specific fans installed. The USB 2.0 interface limits software polling rate compared to faster internal buses, which may affect real-time monitoring granularity.

Perguntas sobre este artigo
My motherboard only has one internal USB 2.0 9-pin header — is that enough for this controller?
Yes, the controller connects through a single internal USB 2.0 9-pin header on the motherboard.
Can I plug my older 3-pin DC fans into the 4-pin x 8 PWM headers and still control them?
The controller provides 4-pin PWM headers; 3-pin fans will run at full speed without PWM control.
After connecting everything, how can I confirm the controller is communicating with the PC?
The device appears in Razer Synapse once the micro-to-USB header cable is seated on the internal USB 2.0 9-pin header.
