4. Setup and Installation

4.1 Compatibility & Clearance Guide

The unique fan bracket displacement design allows two installation modes to avoid conflicts with memory and motherboard I/O:

Memory-Side Fan Offset: Max memory height support 44mm; no I/O height limit.
I/O-Side Fan Offset: Max I/O height support 47mm; no memory height limit.

Choose the mode based on your motherboard and memory configuration before installation.

4.2 Pre-Installation Preparation

Critical Warning: Power off the PC and disconnect all power cables before installation to prevent electrical damage.

Remove any existing CPU cooler and clean residual thermal paste from the CPU IHS with a lint-free cloth and isopropyl alcohol.
Confirm the pre-applied thermal paste on the IS-50X V3 base is intact (reapply a thin, even layer if damaged).
Determine the fan offset mode (memory or I/O side) and adjust the fan bracket position on the cooler accordingly.

4.3 Intel Socket Installation (LGA1700 / LGA1200)

Attach the dedicated Intel mounting backplate to the bottom of the motherboard and secure it with the included standoffs.
Install the mounting brackets on the cooler base using the provided screws.
Align the cooler over the CPU, ensuring the heat pipe base fully contacts the CPU IHS.
Tighten the four spring-loaded mounting screws in a crisscross pattern to ensure even pressure (do not overtighten).
Connect the fan's 4-PIN PWM cable to a CPU fan header on the motherboard.

4.4 AMD Socket Installation (AM5 / AM4)

For AM4: Use the pre-installed AMD mounting brackets on the cooler; align with the motherboard's AM4 mounting holes and fasten the spring clips.
For AM5: Replace the default brackets with the included AM5 mounting kit; secure the backplate and tighten the screws in a crisscross pattern.
Connect the fan's 4-PIN PWM cable to a CPU fan header on the motherboard.

5. Operation and Noise Reduction

5.1 PWM Speed Control

The 120mm fan supports 4-PIN PWM speed regulation (500-2000RPM), automatically adjusting speed based on CPU temperature for a balance of cooling performance and noise.

5.2 Noise Reduction Design

Hydraulic Bearing PLUS: Optimized shaft durability and automatic oil return system extend lifespan while reducing operational noise.
Small Inclined Blades: Aerodynamic blade design minimizes turbulence without sacrificing airflow.
8 Rubber Dampening Pads: Reduces vibration transfer between the fan and cooler frame for ultra-quiet operation.

6. Maintenance & Care

Cleaning: Use compressed air (blown from the fan side to the fin side) every 3-6 months to remove dust from the fins and fan blades. Avoid water contact with the fan bearing.
Fan Maintenance: The fan blades are not designed for disassembly; clean only with compressed air or a soft brush.
Storage: Store the cooler in a cool, dry place with the fan protected to prevent dust accumulation and blade damage.
Handling: Avoid bending the heat pipes or damaging the fin stack during installation or transportation.

7. Troubleshooting

Issue	Solution
CPU Overheating	Verify thermal paste contact (reapply if needed). Ensure mounting screws are tightened evenly. Check fan speed (confirm PWM cable is connected to CPU fan header). Clean dust from fins/fan.
Excessive Fan Noise	Tighten mounting screws to eliminate vibration. Clean dust from fan blades/bearing. Adjust BIOS fan curve to lower minimum speed (if supported). Ensure no cables contact the fan blades.
Cooler Conflicts with Memory/I/O	Reinstall the fan in the alternate offset mode (memory or I/O side). Confirm memory/I/O height is within the 44mm/47mm limit.
Fan Not Spinning	Check the 4-PIN PWM cable connection to the motherboard. Test the fan on a different fan header. Ensure the motherboard fan header is enabled in BIOS.

8. User Tips

For optimal performance, especially with CPUs like Ryzen 5 7600 or 9950x3d, consider setting the fan to 'quiet' in BIOS or adjusting the maximum processor frequency to manage temperatures effectively under heavy load.
The cooler is highly effective for low-profile builds and ITX servers, providing excellent cooling in compact spaces.
While the included fan is good, some users recommend upgrading to an aftermarket fan (e.g., Arctic) for potentially even better performance or lower noise.
The fan's large size can help cool surrounding motherboard components, contributing to overall system stability.
Ensure the motherboard is completely separated from the case during installation for easier access to mounting points.
