3.2 Elektrische Anschlüsse
The FN-12 fan requires two types of connections: one for power/fan speed and one for ARGB lighting.
- Fan Power (3-pin or Molex): Connect the fan's 3-pin connector to an available 3-pin FAN header on your motherboard. Alternatively, if no 3-pin headers are available, connect the Molex connector directly to your power supply.
- ARGB Lighting (5V 3-pin): Connect the fan's 3-pin ARGB connector to a 5V 3-pin ARGB header on your motherboard. This allows for synchronization of lighting effects. The fan includes a Male/Female adapter for compatibility.

Wichtiger Hinweis:
- Consult your motherboard manual to locate the correct 5V 3-pin ARGB header. Do not connect to a 12V 4-pin RGB header, as this may damage the fan.
- If your motherboard lacks a 5V 3-pin ARGB header, you may need an external ARGB controller (sold separately) to control the lighting effects.
4. Bedienungsanleitung
4.1 Lüftergeschwindigkeitssteuerung
When connected directly to a motherboard's 3-pin FAN header or a power supply via Molex, the fan will operate at 100% speed. For variable speed control, a fan controller (sold separately) is required.
4.2 ARGB-Beleuchtungssteuerung
If connected to a compatible 5V 3-pin ARGB motherboard header, you can control the lighting effects using your motherboard's RGB software (e.g., ASUS Aura Sync, MSI Mystic Light Sync, Gigabyte RGB Fusion, ASRock Polychrome Sync). Refer to your motherboard's documentation for specific software instructions.

6. Fehlerbehebung und FAQ
In diesem Abschnitt werden häufig gestellte Fragen und Probleme behandelt, die Ihnen begegnen könnten.
Häufig gestellte Fragen:
- Q: Do I need a special port on my Motherboard?
A: For the fan to spin, you can use a standard 3-pin FAN port, which most motherboards have. For ARGB lighting, you will need a 5V 3-pin ARGB port. Consult your motherboard manual to verify its presence. - Q: What if I don't have the 5V 3-pin ARGB port?
A: If your motherboard does not have this port, you can acquire an external ARGB controller (e.g., MUNFROST Solar Wind 3-fan kit, ASIN: B08DRQ134N) which includes multiple ARGB ports. - Q: Can I control the fan speed of this fan?
A: When connected directly to the motherboard or power supply, the fan will always spin at 100%. To control the fan speed, you would need a fan controller (e.g., included in the MUNFROST Solar Wind 3-fan kit).
