1U Server CPU Cooler for Socket 2011

The Dynatron R18 is a low-profile air cooler built for 1U rackmount servers using Intel Sandy Bridge EP/EX processors on socket 2011. It combines a copper heatsink with skived fins and an 80 mm dual-ball-bearing fan mounted vertically to fit the tight vertical clearance of 1U chassis. The unit weighs 480 g and ships with Shin-Etsu G751 thermal compound pre-applied.

4-Pin PWM Control and Duty-Cycle Limits

Speed, airflow and noise are governed by a 4-pin PWM connector operating at 12 V. At 20 % duty cycle the fan runs at 1000 RPM delivering 6.5 CFM at 21.5 dBA; at 50 % it reaches 3500 RPM for 11.2 CFM at 43.0 dBA; at 100 % it spins to 6000 RPM producing 19.1 CFM at 55.8 dBA. Corresponding power draw rises from .6 W through 3.84 W to 14.4 W, while static pressure climbs from 2.27 mm-H2O to 18.56 mm-H2O and 54.5 mm-H2O across the same steps.

Copper Skived-Fin Heatsink and Vertical Fan Mount

The heatsink uses copper skived fins aligned parallel to system airflow, a construction that maximises fin density in the 15 mm fan depth. Vertical mounting directs air straight through the fin stack toward the chassis exhaust, which suits front-to-back server airflow but does not suit tower cases with top-mounted exhaust. The cooler is rated for CPUs up to 95 W; builders needing higher thermal capacity or a backplate for board-level mounting must look elsewhere.

Questions sur cet article

How does the 95 W TDP rating translate to actual cooling performance in a 1U chassis?

The copper skived-fin heatsink and 80 mm dual-ball fan move 6.5 CFM at 21.5 dBA (20 % duty), 11.2 CFM at 43 dBA (50 %) or 19.1 CFM at 55.8 dBA (100 %), with static pressure up to 54.5 mm-H₂O, keeping Socket 2011 CPUs within thermal limits.

What does the 4-pin PWM connector control on this cooler?

The 4-pin connector feeds 12 V and PWM duty-cycle signals; at 20 % duty the fan runs at 1000 RPM drawing 0.6 W, at 50 % it reaches 3500 RPM and 3.84 W, and at 100 % it spins 6000 RPM consuming 14.4 W.
