Cavo adattatore ventola InLine 12V / 7V con segnale di velocità InLine 33007T

The InLine Fan Adapter Cable 12V / 7V with speed signal (model 33007T) reduces a fan's supply voltage from 12V to 7V to lower operating noise while still transmitting the tachometer (speed) signal to the motherboard for RPM monitoring. The cable is 0.3 m long, uses a 4-pin Molex connector and comes in a multicolour design suited for internal PC installations where quieter fan operation is required.

Advantages

This adapter provides noise reduction by lowering the fan voltage to 7V without interrupting the speed signal, allowing the system to monitor fan RPM. Its 4-pin Molex connector ensures compatibility with standard PC fan headers and power sources, and the short 0.3 m length is convenient for tidy internal cable routing.

Suitable for

• Reducing noise from case or CPU fans in desktop PCs
• Systems where RPM monitoring on the motherboard is required
• PC builds needing a compact, easily routed adapter cable

Key specifications

• Model: InLine 33007T
• Cable length: 0.3 m
• Connector: Molex 4-pin
• Function: Reduces fan voltage from 12V to 7V; passes speed (tachometer) signal
• Colour: Multicolour
• EAN: 4043718043743

How to use

Connect the adapter between the fan power plug and the system power/header so the fan receives 7V instead of 12V while the tachometer wire remains connected to the motherboard. Ensure connectors are fully seated and that the reduced voltage meets the fan manufacturer's allowable operating range. Verify fan speed reporting in the BIOS or monitoring software after installation.

Recommendations

Use this adapter for lowering fan noise in desktop PCs where a moderate reduction in fan speed is acceptable. Do not use if the fan requires full 12V for proper operation or if the manufacturer advises against voltage modification. Check system monitoring to confirm stable RPM readings after fitting the cable.
