Koeler Inter-Tech B-3 processor 8 cm grijs 1000-4000 tpm 16-44,9 dB

The Cooler Inter-Tech B-3 Processor 8 cm in grey is a compact CPU cooling solution designed for efficient heat dissipation in space-constrained builds. Equipped with an 8 cm fan, it delivers variable rotational speeds from 1,000 to 4,000 RPM and produces airflow rated up to 21 CFM. The cooler's small footprint (107 mm × 80.5 mm × 28 mm) allows installation in a wide range of cases where larger tower coolers would not fit. Noise output ranges from 16 dB at low speed to 44.9 dB at maximum speed, giving a balance between quiet operation and peak cooling performance.

Advantages

The Inter-Tech B-3 offers compact dimensions that suit small form-factor systems and standard cases where space is limited. Its wide fan speed range enables adaptive cooling: lower speeds for silent or office use and higher speeds for demanding workloads. With a maximum airflow of 21 CFM, the cooler supports stable CPU temperatures under moderate loads while the noise specifications give a clear expectation of acoustic behavior at different speeds. The grey finish provides a neutral look that integrates with most system color schemes.

Suitable for

• Small form-factor desktop PCs where space for cooling is restricted
• Office and home computers requiring low-noise operation at idle or light load
• Systems that need occasional bursts of higher cooling performance for short workloads
• Budget builds seeking a compact, straightforward processor cooler

Key specifications

• Fan diameter: 80 mm (8 cm)
• Rotational speed: 1,000–4,000 RPM
• Noise level: 16–44.9 dB
• Maximum airflow: 21 CFM
• Dimensions (W × D × H): 107 mm × 80.5 mm × 28 mm
• Color: Grey

How to use

Mount the cooler onto the compatible processor socket following the case and motherboard manufacturer's instructions. Ensure the fan orientation allows airflow through the cooler and into the case exhaust path for effective heat removal. Connect the fan cable to the CPU fan header on the motherboard or to an appropriate fan controller to allow speed regulation within the 1,000–4,000 RPM range. Verify clearance around adjacent components and routing of cables to avoid obstructing the fan.

Recommendations

For quiet everyday use, configure the fan curve or set the fan to operate at lower RPMs where noise is around 16 dB. During intensive tasks, allow the fan to increase speed toward the higher end of its range to utilize the maximum 21 CFM airflow. Regularly clean the fan and heatsink area from dust to maintain performance and check mounting tightness after initial installation and during routine maintenance.
