Server-Class Socket FCLGA3647 Cooler

The Dynatron B13 is a new CPU air cooler built for Intel Xeon processors on the FCLGA3647 socket. Its 66 mm height and vertical 60 mm fan suit 2U server chassis and up. The unit weighs 430 g and uses an aluminium heatsink with an embedded heatpipe.

Pre-Printed Shin-Etsu 7762 Thermal Grease

Shin-Etsu 7762 compound is pre-printed on the base, removing the need to apply paste manually. This ensures consistent coverage for the square ILM and saves installation time in rack environments. No additional software or mounting kits are mentioned in the specifications.

60 mm PWM Fan With 2-Ball Bearing

The 4-pin PWM fan runs from 1,400 RPM at twenty percent duty to 7,000 RPM at full speed, delivering 8.12 to 40.60 CFM. Noise rises from 16 dBA to 50 dBA across the same range. Builders needing lower acoustic output or higher static pressure for denser fin stacks will find this cooler unsuitable.

Questions about this item

How often will the 2-ball bearing fan need replacement in a 2U server running continuously?

The 2-ball bearing fan is rated for continuous operation; typical service intervals exceed several years, and no scheduled replacement cycle is defined by the manufacturer.

At what point does the 60 mm fan hit its 7000 RPM ceiling under sustained load?

The fan reaches 7000 RPM at 100 % PWM duty cycle, delivering 40.60 CFM while producing 50 dBA.

What noise and heat output should I expect when the cooler runs at full speed all day?

At 100 % duty cycle the fan spins at 7000 RPM, moves 40.60 CFM and emits 50 dBA; the aluminum heatsink with embedded heatpipe dissipates the thermal load into the chassis airflow.
