2U Server Cooler for LGA 2011

The Dynatron R5 is a 60 mm dual-ball-bearing CPU air cooler built for Intel Sandy Bridge EP and EX processors up to 150 W. Its H.C.C. copper base contacts the CPU directly while four 6 mm heatpipes feed high-density aluminium fins. A 60 x 60 x 25 mm PWM fan spins from 1600 RPM at low duty to 8000 RPM at full duty, pushing 8.75 to 43.75 CFM. The unit stands 66 mm tall, weighs 590 g, and mounts with standard server bolt-thru hardware.

Suits 2U-and-up server builds

This cooler fits 2U and taller server chassis that can accommodate a 66 mm stack height and need a 150 W thermal solution for LGA 2011 square-type sockets. It is not for systems limited to lower-profile coolers, for builds requiring quieter operation than 51 dBA at maximum fan speed, or for platforms using any socket other than LGA 2011.

66 mm maximum cooler height

The 66 mm overall height is the critical dimension that determines whether the R5 clears the chassis lid and adjacent components in a 2U rack. Verify the available vertical clearance in your enclosure before purchase; if the space is smaller, this cooler will not fit.

Questions about this item

How long will the dual-ball bearing fan last before it needs replacing?

The 2 ball bearing fan is rated for continuous operation at up to 8000 RPM, and the cooler weighs 590 g with a 66 mm max height for 2U server chassis.

What thermal limit appears first when the CPU runs at 150 W continuously?

The cooler is validated for Intel Sandy Bridge EP/EX processors up to 150 W using four 6 mm heatpipes and a copper base in direct contact with the CPU.

How loud does the 60 mm PWM fan get at full speed in a 2U server running all day?

At 100 % duty cycle the fan spins at 8000 RPM, moves 43.75 CFM and produces 51.00 dBA while drawing 7.2 W at 12 V.
