Cooler Dynatron B5 Processor Cooling System Aluminium Black

The Dynatron B5 is a compact aluminium CPU cooler finished in black, designed for Intel Socket FCLGA3647 Narrow ILM installations in 2U server environments. It combines an aluminium heatsink with an embedded heatpipe and a PWM-controlled fan (200–7000 RPM) to support processors with TDP up to 205 W while keeping overall dimensions suitable for constrained rack-mounted systems.

Advantages

The cooler offers a slim 60 × 60 × 25 mm fan footprint paired with an aluminium heatsink and integrated heatpipe for effective heat transfer. PWM fan control provides wide speed range for flexible cooling and noise management. Ball bearing construction improves durability and service life, and the black aluminium finish ensures corrosion resistance and a neutral appearance inside server chassis.

Suitable for

• 2U rack servers with Intel FCLGA3647 Narrow ILM sockets
• High-density systems requiring low-profile cooling
• Environments where a compact cooler supporting up to 205 W CPU power is needed

How to use

Install the Dynatron B5 on a compatible Intel FCLGA3647 Narrow ILM socket following server manufacturer mounting instructions. Apply a thin, even layer of thermal compound to the CPU heatspreader before seating the cooler. Secure the cooler using the intended retention mechanism for your 2U chassis, ensuring the heatsink and fan clear adjacent components and airflow paths. Connect the PWM fan cable to the server motherboard or fan controller to enable automatic speed control.

Recommendations

For reliable operation, verify chassis clearance and airflow direction in your 2U server before installation. Ensure the server BIOS or fan controller is configured to allow PWM control and monitor fan speeds and CPU temperatures under expected load. Clean dust from the heatsink and fan periodically to maintain cooling efficiency.
