Important Considerations:
- RAM Clearance: Due to the cooler's size, ensure your RAM modules (especially high-profile ones) have adequate clearance. You may need to adjust fan placement or use low-profile RAM.
- Case Compatibility: Verify your PC case has sufficient width and height to accommodate the 154.9mm tall cooler.
- Thermal Paste: Apply the included CryoFuze thermal paste evenly to the CPU's integrated heat spreader (IHS) before mounting the heatsink.

Operating
ARGB Lighting Control
The Hyper 620S features ARGB Auto Detection, providing default spectrum lighting upon power-up. For full customization, connect the ARGB cable to a compatible motherboard header (e.g., ASUS Aura Sync, MSI Mystic Light Sync, GIGABYTE RGB Fusion, ASRock Polychrome RGB) and use the motherboard's software to control lighting effects.

Fan Speed Management (PWM)
The 4-pin PWM fan connector allows your motherboard to dynamically control fan speeds based on CPU temperature. This ensures optimal cooling performance while minimizing noise during lighter loads. You can typically configure fan curves within your motherboard's BIOS/UEFI settings or through dedicated software.
Maintenance
Cleaning
Regular cleaning is essential to maintain optimal cooling performance. Use compressed air to remove dust from the heatsink fins and fan blades. For stubborn dust, gently wipe the fan blades with a soft, dry cloth. Ensure the system is powered off and unplugged before cleaning.
Thermal Paste Reapplication
Over time, thermal paste can dry out and lose effectiveness. It is recommended to reapply thermal paste every 2-3 years, or if you notice a significant increase in CPU temperatures. Carefully remove the cooler, clean off old thermal paste from both the CPU and cooler base using isopropyl alcohol, and apply a fresh layer of CryoFuze thermal paste before re-installing the cooler.
Troubleshooting
- High CPU Temperatures: Ensure the cooler is properly seated and tightened. Verify thermal paste application. Check fan connections and ensure they are spinning. Ensure adequate airflow within your PC case.
- Fans Not Spinning/No RGB: Check all fan and ARGB cable connections to the motherboard. Ensure your motherboard's ARGB header is enabled in BIOS/UEFI. Test fans with a different header if possible.
- Noise Issues: Verify fans are securely mounted and not vibrating against other components. Adjust fan curves in BIOS/UEFI to reduce speeds during idle or low-load situations.
- Installation Difficulties: Refer to the detailed diagrams and instructions in the included user manual. Ensure you are using the correct mounting hardware for your specific CPU socket.
