3. Installation Guide
The FROZN A620 SLK is designed for fast and hassle-free installation with a simplified mounting system. No fan removal or wire clips are required during the main installation process.
General Installation Steps:
- Prepare Motherboard: Ensure your motherboard is removed from the PC case or has sufficient access to the CPU socket area.
- Install Backplate: Depending on your CPU socket (Intel or AMD), adjust the backplate screws to the correct position and install the backplate on the rear of the motherboard.
- Attach Standoffs: Secure the appropriate standoffs onto the backplate screws from the front side of the motherboard. Use the provided standoff fastening tool if necessary.
- Mount Brackets: Place the multi-platform mounting brackets onto the standoffs and secure them with the tightening nuts.
- Apply Thermal Paste: Apply a small amount of thermal paste (included) to the center of your CPU's integrated heat spreader (IHS).
- Position Cooler: Carefully place the FROZN A620 SLK heatsink onto the CPU, aligning the mounting holes on the cooler with the brackets.
- Secure Cooler: Remove the magnetic top cover of the cooler to access the screw holes. Use the provided screwdriver to tighten the two fasteners into the mounting brackets. Tighten screws alternately until snug.
- Connect Fans: Connect the fan cables to the CPU fan header on your motherboard. The cooler includes a Y-splitter for both fans.
- Replace Top Cover: Snap the magnetic top cover back onto the heatsink.

Fan Characteristics:
- Front Fan: Operates at 500-1850 RPM, providing 65.2 CFM airflow with a maximum noise level of 33.9 dB(A).
- Middle Fan: Operates at 0-2500 RPM, providing 79.7 CFM airflow with a maximum noise level of 31.0 dB(A).
- The combined system ensures efficient cooling while maintaining a manageable noise profile.
5. Maintenance
Regular maintenance helps ensure the longevity and optimal performance of your CPU cooler.
Cleaning:
- Dust Removal: Periodically inspect the heatsink fins and fan blades for dust accumulation. Use compressed air to gently blow dust away from the fins and fans. Ensure the fans are held stationary during cleaning to prevent damage to the bearings.
- Fan Cleaning: For stubborn dust, carefully wipe the fan blades with a soft, dry cloth.
Thermal Paste:
- Reapplication: Thermal paste typically lasts for several years. If you remove the cooler from the CPU for any reason, it is recommended to clean off the old thermal paste from both the CPU and the cooler's base and apply a fresh layer before reinstallation.
6. Troubleshooting
If you encounter issues with your FROZN A620 SLK cooler, refer to the following common problems and solutions:
High CPU Temperatures:
- Check Installation: Ensure the cooler is securely mounted and making proper contact with the CPU. Uneven pressure can lead to poor thermal transfer.
- Thermal Paste: Verify that thermal paste was applied correctly and evenly. Reapply if necessary.
- Fan Operation: Confirm that both fans are spinning. Check fan connections to the motherboard.
- Airflow: Ensure adequate airflow within your PC case. Check case fan orientation and remove any obstructions.
- Dust Buildup: Clean any dust from the heatsink fins and fan blades.
Excessive Fan Noise:
- Fan Speed Control: Check your motherboard's BIOS/UEFI settings or fan control software to ensure fan speeds are set appropriately.
- Obstructions: Inspect fans for any cables or objects that might be interfering with their rotation.
- Dust: Clean fans if dust buildup is causing imbalance or increased noise.
Cooler Not Fitting:
- RAM Clearance: The FROZN A620 SLK is designed for high RAM compatibility. However, ensure your RAM modules are correctly seated and not obstructing the cooler's base.
- Case Clearance: Verify that your PC case has sufficient clearance for the cooler's dimensions (refer to your case specifications).
