Dynatron R5 2U Active Server CPU Cooler (LGA2011/2066)
2U ActiveIntel LGA2011/2066Copper BaseUp to 165W
The Dynatron R5 is a 2U active CPU cooler for Intel Socket LGA2011 and LGA2066 (Square ILM), pairing a copper base and aluminium fin stack with a high-speed 60mm PWM fan. Rated to 165W, it is built for 2U rackmount servers and workstations running Xeon E5/E7 and Core X-series processors. Part number 88885172, it stands 66mm tall and installs with pre-applied thermal paste. It is a purpose-built server cooler for high-airflow chassis. Typically in stock with fast delivery across Cyprus.
Compatibility — check before buying:
For Intel LGA2011 and LGA2066 with the Square ILM mounting, in 2U (and taller) rackmount chassis. Confirm your board uses Square ILM (not Narrow ILM) and that your processor’s TDP is within 165W. Its small fan reaches high RPM, so it is intended for server/workstation use rather than noise-sensitive desktops.
Best For
✓2U rackmount servers and workstations
✓Intel LGA2011 / LGA2066 Square ILM platforms
✓Xeon E5/E7 and Core X-series processors
✓High-airflow chassis needing active cooling
✓Genuine spare-part replacements for 2U systems
✓CPUs rated up to 165W
Key Features
2U Active Cooling
A 60mm PWM fan provides directed airflow through the fin stack in a 66mm-tall body, fitting 2U chassis where taller tower coolers cannot go.
Copper Base
A copper contact base with aluminium fins transfers heat efficiently from LGA2011/2066 processors rated up to 165W.
Square ILM Fit
Built specifically for the Square ILM mounting used by Intel LGA2011 and LGA2066 workstation and server boards.
Wide PWM Range
The fan scales from 1,700 to 8,500 RPM (up to 46.44 CFM), letting the server tune airflow precisely to CPU load and inlet temperature.
Technical Specifications
Frequently Asked Questions
Which processors does the R5 cool?
It fits Intel LGA2011 and LGA2066 processors with the Square ILM mounting — Xeon E5/E7 and Core X-series — rated up to 165W.
Is it Square ILM or Narrow ILM?
Square ILM. Confirm your server or workstation board uses Square ILM before ordering, as Narrow ILM boards need a different heatsink.
Is it active or passive?
Active. It uses a 60mm PWM fan for directed airflow, suiting 2U chassis rather than relying purely on the chassis fan wall.
Will it fit a desktop tower?
It is built for 2U rackmount use. In a standard desktop a tower cooler or AIO will run cooler and quieter; the R5 targets high-airflow server chassis.
Singular Expert Insight
The R5 is a specialist 2U cooler for the LGA2011/2066 Square ILM platform, so the key checks are ILM type and 2U clearance rather than raw performance. For weaker-airflow chassis a larger heatsink may help, and for desktop X-series builds a tower or AIO in our CPU coolers range will be quieter. When commissioning a server or workstation, confirm your power supply and chassis airflow suit the CPU you are cooling.
Buyer's Guide
Buy it if
You are building or servicing a 2U Intel LGA2011/2066 Square ILM server or workstation up to 165W.
Skip it if
Your board uses Narrow ILM, you have a desktop tower, or your CPU exceeds 165W and needs more cooling.
Also consider
A Narrow ILM heatsink if your board needs it, or a tower cooler for desktop X-series builds.
