6. Betjening av etuiet
6.1. Slå på
Once all components are installed and connected, press the power button on the top I/O panel to start your system.
6.2. ARGB-viftekontroll
The pre-installed ARGB PWM fans can be controlled via your motherboard's software if it supports Addressable RGB (ARGB) and PWM fan control. Connect the ARGB cables to the appropriate 3-pin 5V ARGB header and the PWM fan cables to 4-pin fan headers on your motherboard.
7. Vedlikehold
7.1. Rengjøring av støvfiltre
The TH285 case includes removable dust filters to prevent dust buildup. Regularly clean these filters by gently removing them and washing them with water or brushing off accumulated dust. Ensure they are completely dry before re-installing.
7.2. Generell rengjøring
Use a soft, dry cloth to wipe down the exterior of the case, including the tempered glass panels. For stubborn smudges on glass, a mild glass cleaner can be applied to the cloth (not directly to the glass) and then wiped clean.
8. Feilsøking
- Systemet slår seg ikke på: Ensure all power cables (24-pin ATX, 8-pin CPU, GPU power) are securely connected. Verify the PSU switch is in the 'ON' position. Check front panel power button connection to the motherboard.
- Fans are not spinning or ARGB lighting is not working: Confirm fan PWM and ARGB cables are correctly connected to the motherboard headers. Check motherboard software for fan speed and lighting control settings.
- Ingen skjermutgang: Ensure the GPU is properly seated in its PCIe slot and connected to power. Verify the monitor cable is connected to the GPU, not the motherboard integrated graphics (unless using integrated graphics).
