Angled bottom fan bracket HAVN HS 420 black for case fan mounting

Angled bottom fan bracket HAVN HS 420 black is a mounting accessory designed to secure a case fan at an angled lower position. Compatible with standard fan sizes, it enables stable installation on the bottom panel of a PC case and reorients airflow to improve ventilation and cooling layout. The bracket is intended for use in custom builds and upgrades where repositioning of fans can help reduce component temperatures and optimize internal airflow paths.

Advantages

The angled bottom fan bracket provides a compact, robust mounting solution that holds a case fan securely at a fixed tilt without requiring permanent modifications to the chassis. Its design allows the fan to direct airflow toward targeted components or exhaust zones, and the black finish integrates with common case interiors. The bracket supports easy installation and removal for maintenance and offers consistent alignment to minimize vibration and noise transfer to the case.

Suitable for

• Custom PC builds where bottom-mounted, angled airflow is required
• Upgrades to existing systems to improve ventilation around GPUs and power supplies
• Systems with constrained top or rear exhaust where redirected airflow is beneficial
• Enclosures needing flexible fan placement without drilling or cutting

Key specifications

• Mounting position: bottom panel, angled orientation
• Compatibility: standard case fan sizes (typical 120 mm and 140 mm form factors)
• Material: rigid mounting material with vibration-damping contact points
• Finish: black surface for discreet in-case appearance
• Installation method: screw-mounted to case bottom; tool-assisted mounting

How to use

Position the bracket on the case bottom in the desired location, aligning the bracket mounting holes with existing case screw holes or designated mounting points. Attach the bracket using the appropriate screws, then mount the case fan onto the bracket, ensuring the fan orientation matches the intended airflow direction. Secure all fasteners evenly to maintain the angled position and check for clearance with internal components. Reconnect fan power and verify operation before closing the case.

Recommendations

Use appropriate fan sizes and check clearance around the GPU, PSU shroud, and drive cages before final installation. For reduced vibration and noise, use rubber grommets or anti-vibration screws if available and ensure screws are snug but not overtightened. Periodically inspect the bracket and fan mounting during maintenance to confirm secure attachment and optimal airflow direction.
