2. Product Features
- Industrial Grade Case Fan: Automatic speed control via 4-pin PWM fan cable interface, adjusting speed based on motherboard temperature, with a maximum speed of 2150 RPM.
- Advanced Balancing Process: Fan blade undergoes initial correction and then laser balancing with three dots of balancing clay to ensure optimal dynamic balance and performance.
- High Precision S-FDB Bearing: Sealed construction S-FDB bearings provide long durability, enhanced cooling performance, minimal noise, and extended service life.
- Optimized Airflow Design: Triangular symmetrical back frame design increases effective airflow area and enhances static pressure for improved cooling.
- Versatile Application: Suitable for use as a case fan, with CPU coolers, radiators, and other cooling applications to dissipate heat effectively.

3. Installation Guide
Follow these steps for proper installation of your Thermalright TL-B12 fan. Refer to the video for a visual demonstration.
Video 3.1: Installation guide for Thermalright case fans. This video demonstrates how to identify airflow direction, use vibration-free mounts, and secure the fan in a PC case, and connect the fan header to the motherboard.
3.1 Airflow Direction
Before installation, identify the fan's airflow direction. Air typically flows from the side with the fan blades visible to the side with the fan frame structure. The fan blade side is generally the intake, and the frame side is the exhaust.

3.2 Mounting the Fan
The TL-B12 fan can be mounted using either vibration-free mounts or standard screws, depending on your case and preference.
- Using Vibration-Free Mounts: Insert the rubber mounts through the fan's mounting holes and then through the corresponding holes on your PC case. Pull the end of the mount to secure the fan in place.
- Using Screws: Align the fan with the mounting holes on your PC case. Use a screwdriver to secure the fan with the provided screws. Ensure both screws are tightened evenly to prevent vibration.

3.3 Connecting the Fan
Connect the fan's 4-pin PWM connector to an available 4-pin fan header on your motherboard. This allows the motherboard to control the fan speed automatically based on system temperature.
4. Operation
The Thermalright TL-B12 fan is designed for high-performance cooling with intelligent speed control.
- PWM Control: The 4-pin PWM interface enables your motherboard to dynamically adjust the fan speed (up to 2150 RPM) according to the system's thermal demands, optimizing cooling efficiency and noise levels.
- S-FDB Bearing: The high-precision S-FDB (Stably-FDB) bearing with magnetic design ensures stable fan blade motion, contributing to quiet operation and extended product lifespan.
5. Maintenance
To ensure optimal performance and longevity of your fan, observe the following maintenance guideline:
- Balancing Clay: The fan blades are precisely balanced with red balancing clay. Do not remove this material, as it is crucial for maintaining the fan's dynamic balance and performance.
- Cleaning: Periodically clean the fan blades and frame to prevent dust buildup, which can impede airflow and reduce cooling efficiency. Use a soft brush or compressed air for cleaning.
