Passive heatsink for LGA 2011

The Dynatron R8 is a fanless copper-base heatsink with three heatpipes and aluminium stacked fins. It fits Intel LGA 2011 sockets using the square 80 mm mounting pitch. The unit is designed for Sandy Bridge EP and EX processors in servers or workstations where silent operation or ducted airflow is required.

64 mm height limit

Overall dimensions are 90.0 x 90.0 x 64.0 mm, making the cooler 64 mm tall. This low profile allows installation in 1U and other space-constrained chassis that cannot accommodate taller tower coolers. Verify your case or rack clearance before ordering.

Sustained load without a fan

With no integrated fan, thermal performance depends entirely on system airflow directed through the fin stack. Under continuous load the heatsink relies on case or duct fans to move air across the aluminium fins. In enclosures with weak or misdirected airflow temperatures will rise steadily, so this cooler suits builds with strong, managed airflow paths.

Questions about this item

How does the 64 mm height affect case compatibility?

At 64 mm tall the cooler fits in most 1U and low-profile chassis where taller towers cannot be installed.

What does the 80 mm square mounting pitch mean for installation?

It matches the standard LGA 2011 square ILM hole pattern so the cooler bolts directly onto the socket without an adapter bracket.

Will the 90 mm footprint clear tall memory modules on a server board?

The 90 mm square base leaves the DIMM slots exposed so standard-height registered DIMMs install without interference.
