Copper heatsink for legacy Intel CPUs

The Dynatron K129 is a passive copper heatsink measuring 90.0 x 90.0 x 26.5 mm and weighing 490g. It is designed for Intel Core i5 I5-750, Core i7 I7-860, Core i7 I7-870 and Xeon Processor 3400 Series processors.

Suited for direct replacement on listed sockets

This cooler suits technicians replacing a missing or damaged heatsink on systems running the specific Intel models named above. It is not for builders assembling new platforms, users needing active fan cooling, or anyone whose processor is not explicitly listed in the supported CPU lineup.

Copper construction defines thermal capacity

The solid copper heatsink material provides the thermal mass and conductivity for these specific legacy processors. Buyers must verify their exact CPU model matches the supported list before purchase, as no other compatibility is implied.

Questions about this item

Will the 90.0 mm copper base clear the components around the socket used by the Core i5-750?

The heatsink measures 90.0 x 90.0 x 26.5 mm and weighs 490g, so check your motherboard keep-out zone against those dimensions before fitting.

Can I keep my Xeon 3400 series processor when installing this cooler?

The K129 lists the Xeon 3400 series and Core i7-860 and i7-870 as supported CPUs, so the cooler is designed for those processors.

How do I confirm the K129 is seated correctly after mounting?

Verify the copper base makes full contact with the CPU heatspreader and that the 90.0 x 90.0 mm footprint sits flat within the socket retention frame.
