Betrieb
Anschlüsse an der Vorderseite
The top panel of the VK4 Rainbow case provides convenient access to essential ports:
- 2x USB 3.0-Anschlüsse: Für Hochgeschwindigkeits-Datenübertragung mit kompatiblen Geräten.
- 1x TRRS Port: A combined audio jack for headsets with a single 3.5mm plug (microphone and audio).
- Netzschalter: To turn your system on/off.
- Reset-Taste: Um Ihr System neu zu starten.
Lüfterbetrieb
The four pre-installed 120mm rainbow effect fans are connected via Molex connectors. Due to this connection type, the fans operate at a constant speed and their speed cannot be adjusted via the motherboard. This ensures consistent airflow but may result in a noticeable fan noise level.
Wartung
Regelmäßige Wartung trägt dazu bei, die optimale Leistung und Langlebigkeit Ihrer PC-Komponenten zu gewährleisten.
Reinigung des Staubfilters
- The VK4 Rainbow features pre-installed dust filters at all air intake points (front, top, and bottom).
- Periodically remove and clean these filters to prevent dust buildup inside the case, which can impede airflow and component cooling.
- Filters can typically be cleaned with compressed air or by rinsing with water and allowing them to dry completely before reinstallation.
Allgemeine Reinigung
- Verwenden Sie ein weiches, trockenes Tuch, um die Außenflächen des Gehäuses abzuwischen.
- Für die gehärtete Glasscheibe verwenden Sie einen Glasreiniger und ein Mikrofasertuch, um Streifenbildung zu vermeiden.
- Ensure the system is powered off and unplugged before performing any cleaning inside the case.
Fehlerbehebung
In diesem Abschnitt werden häufig auftretende Probleme behandelt.
- High Fan Noise: The pre-installed fans are connected via Molex and operate at a constant speed. If fan noise is a concern, consider replacing the fans with PWM-controlled alternatives that can be regulated by your motherboard.
- Schlechte Luftzirkulation/Überhitzung:
- Check if dust filters are clean and not obstructed.
- Stellen Sie sicher, dass alle Gehäuselüfter ordnungsgemäß laufen.
- Verify that cables are neatly managed and not blocking airflow paths.
- Schwierigkeiten mit dem Kabelmanagement: While the case offers space, complex builds with many components may require careful planning. Utilize cable ties and routing channels effectively.
- Anschlüsse an der Vorderseite funktionieren nicht:
- Ensure the front panel connectors (USB 3.0, audio, power, reset) are correctly plugged into the motherboard headers.
- Prüfen Sie im Handbuch Ihres Motherboards, welche Pinbelegung für die Stiftleisten korrekt ist.
