InLine Fan Adapter Acrylic 120mm to 70/80/90mm for heat sink

Use this InLine fan adapter to mount a 120 mm fan on a heatsink that has mounting holes for 70, 80 or 90 mm fans. The adapter is made from transparent blue acrylic and provides a stable connection while allowing the larger fan to deliver the same airflow at lower rotational speed, which typically reduces noise. The package includes screws and washers for installation.

Advantages

The acrylic construction is lightweight and durable, offering a clear finish that fits a variety of setups. By enabling the use of a 120 mm fan on smaller mounting patterns, the adapter helps achieve similar airflow with lower fan RPM, which can improve acoustic performance. It comes with the necessary screws and washers for a straightforward installation.

Suitable for

• Replacing a 70/80/90 mm fan with a 120 mm fan on a CPU or GPU heatsink
• Improving cooling and reducing fan noise in small form-factor builds
• Retrofitting older heatsinks to accept modern 120 mm fans

Key specifications

• Compatible fan diameter: 120 mm
• Supported mounting hole patterns: 70 mm, 80 mm, 90 mm
• Material: transparent blue acrylic
• Includes: screws and washers
• Brand: InLine, MPN: 36011, EAN: 4043718089109

How to use

Position the adapter over the heatsink so that its mounting holes align with the existing 70, 80 or 90 mm holes. Place the 120 mm fan on the adapter, align the fan’s mounting holes with the adapter, and secure the assembly using the supplied screws and washers. Ensure screws are tightened evenly to avoid bending the adapter and that the fan cable is routed to avoid obstruction.

Recommendations

Choose a 120 mm fan with appropriate static pressure and RPM range for your heatsink to balance cooling performance and noise. Check clearance inside your case to ensure the larger fan will fit without interfering with other components.
