Adaptérový kabel pro PC ventilátory InLine 12 V / 5 V pro až 3 ventilátory 33005A

The InLine PC Fan Adapter Cable 12V / 5V (model 33005A) reduces the supply voltage of up to three PC fans from 12 V to 5 V to lower fan speed and noise. The 0.15 m multicolour cable provides a compact connection solution for integrating quieter fans into a desktop or small-form-factor PC.

Advantages

By stepping the voltage down from 12 V to 5 V, the adapter cable decreases fan rotational speed and acoustic noise without altering fan wiring or requiring additional controllers. It supports up to three fans from a single input, offers simple installation due to its short length and standard connectors, and is compatible with common 3-pin fan connectors used in PC systems.

Suitable for

• Reducing noise in desktop and home PC cooling setups
• Connecting up to three 3-pin fans to a single fan header or power source
• Small builds where space for fan controllers is limited
• Lowering fan speed for less demanding cooling scenarios

Key specifications

• Brand: InLine
• Model / MPN: 33005A
• EAN: 4043718068166
• Input voltage: 12 V (adapter reduces output to 5 V)
• Output voltage: 5 V (to fans)
• Supported fans: up to 3 fans (standard 3-pin connectors)
• Cable length: 0.15 m

How to use

Connect the adapter cable input to a 12 V fan header or appropriate 12 V power source in your PC. Attach up to three 3-pin fan connectors to the adapter outputs. Ensure connectors are fully seated and oriented correctly. After installation, power on the system and confirm that the connected fans operate at reduced speed and produce less noise. If fan speed is too low for required cooling, remove the adapter or use fans with higher airflow at lower voltages.

Recommendations

Use the adapter where reduced fan noise is prioritized over maximum cooling performance; verify system temperatures under typical load after installation to ensure adequate cooling. Avoid using the adapter on fans required for critical high-temperature components without monitoring.
