Compact 1U cooler for LGA 2011 servers

The Dynatron R16 is a low-profile air cooler designed for Intel LGA 2011 square-type sockets. It fits 1U chassis with a maximum height of 28 mm. The unit uses a vapor-chamber base with copper stacked fins and an 80 mm fan mounted horizontally. It targets Sandy Bridge EP and EX processors in space-constrained rack environments.

Quiet at idle with a 4-pin PWM fan

At a 20 % duty cycle the fan spins at 1000 RPM, moving 6.5 CFM at 21.5 dBA while drawing 0.6 W. At 50 % duty cycle speed rises to 3500 RPM for 11.2 CFM at 43.0 dBA and 3.84 W. The 2 ball bearing and PWM control allow the motherboard to balance airflow against acoustic output automatically.

Sustained load pushes fan to 6000 RPM

At 100 % duty cycle the fan reaches 6000 RPM, delivering 19.1 CFM and 54.5 mm-H₂O static pressure at 55.8 dBA with 14.4 W power draw. This headroom handles continuous thermal loads typical of dense server deployments. The cooler is not suited for builds needing taller heatsinks or alternative socket platforms.

Questions about this item

How do I mount the R16 on an LGA 2011 socket and what step is often missed?

The cooler uses a horizontal fan mount on the vapor-chamber base; the step often missed is seating the 28 mm tall assembly squarely before tightening the LGA 2011 square-type retention screws so the vapor chamber makes full contact.

What part of the R16 will need replacement first and when?

The 80 mm dual-ball-bearing fan rated at 12 V is the only moving part; expect to replace it once bearing noise rises above the 21.5 dBA baseline at 20 % duty cycle.

At what point does the R16 hit its thermal limit during sustained load?

At 100 % duty cycle the fan reaches 6000 RPM, 19.1 CFM and 55.8 dBA; that is the maximum cooling capacity before temperatures climb.
