Ventilador Inter-Tech B-9 9 cm gris 1000-2500 rpm 16-31,5 dB

The Inter-Tech B-9 9 cm processor cooler is a compact cooling solution designed for quiet and efficient heat dissipation in small to medium PC builds. With an adjustable speed range from 1000 to 2500 RPM and a noise footprint between 16 and 31.5 dB, this cooler balances airflow and acoustic performance. Its ball bearing construction increases durability and supports continuous operation. The cooler's compact dimensions make it suitable for compact cases and systems with limited clearance.

Advantages

The cooler delivers targeted airflow of up to 19 CFM while maintaining low noise levels at typical operating speeds, making it suitable for systems where acoustic comfort is important. The ball bearing design offers extended lifespan compared with sleeve-bearing alternatives and provides reliable performance under varied thermal loads. The small 9 cm form factor allows installation in constrained spaces without significant compromise to airflow.

Suitable for

• Small form-factor desktop PCs and mini-towers
• Home and office systems with low to moderate CPU heat output
• Replacement or upgrade for compact stock coolers
• Quiet builds where reduced noise is a priority

Key specifications

• Fan diameter: 9 cm
• Speed range: 1000–2500 RPM
• Noise level: 16–31.5 dB
• Bearing type: ball bearing
• Maximum airflow: 19 CFM
• Compact dimensions suitable for limited clearance setups

How to use

Mount the Inter-Tech B-9 according to your motherboard and case layout, ensuring secure attachment to the CPU socket or heatsink bracket provided by your system. Connect the fan power cable to the appropriate fan header on the motherboard or a compatible controller that supports the voltage range for 1000–2500 RPM operation. Before first use, verify that the fan spins freely and that airflow direction aligns with your case ventilation scheme. Monitor CPU temperatures during initial operation to confirm adequate cooling and adjust fan control settings if supported by the motherboard.

Recommendations

For best results in compact systems, combine the Inter-Tech B-9 with balanced case airflow (intake and exhaust) and keep dust filters clean to maintain the rated airflow and noise characteristics. If lower noise is critical, configure a mild fan curve or limit maximum RPM through motherboard fan control while monitoring temperatures to ensure safe CPU operation.
