Intel LGA 2011 narrow cooler

The Dynatron R27 is a compact air cooler built for Intel LGA 2011 narrow-type sockets. It uses an 80 mm fan with a 2-ball bearing and four heat pipes featuring H.C.C. technology. The unit stands 110 mm tall and weighs 550 g, making it suitable for space-constrained server or workstation builds.

Airflow and noise headroom

At 20 % duty the fan runs at 1000 RPM, delivering 13.8 CFM at 16.0 dBA. At 50 % duty it reaches 2000 RPM with 30.78 CFM at 31.5 dBA. At full 100 % duty the speed hits 3800 RPM, moving 65.4 CFM at 43.4 dBA, giving installers a wide range between quiet operation and maximum thermal capacity.

80 mm fan mounting limits

The fan mounts horizontally on the heatsink with fixed 80 x 80 x 38 mm dimensions. This footprint restricts use to chassis that can accommodate the 110 mm overall height and the specific narrow LGA 2011 mounting pattern. Builders needing higher airflow or broader socket support will need a different cooler design.

Questions about this item

Will the 110 mm tall R27 fit alongside the tall DIMMs I already have on my LGA 2011 narrow board?

The cooler stands 110 mm high, so measure from the motherboard to your side panel and check DIMM clearance against the horizontal fan mount before installing.

How do I confirm the 2‑ball bearing fan is running at the correct speed after I plug it in?

At 20 % duty the fan should spin at 1000 RPM, at 50 % it reaches 2000 RPM, and at 100 % it hits 3800 RPM — compare BIOS or software readings to those figures.

Does the box include mounting hardware for the LGA 2011 narrow socket or do I need a separate kit?

The package contains the heatsink with four heat pipes, the 80 mm fan pre‑mounted horizontally, and the Intel LGA 2011 narrow mounting brackets — no extra parts are required.
