The NH-D15 uses a dual-heatsink design and the heatsink itself has been given colossal dimensions which measure: 165 mm (Height) x 150 mm (Width) x 135 mm (Depth). The enormity of this heatsink is only really appreciated once it’s installed on the motherboard (on the next page). Even though D15 is large, it still retains that all-important 165mm of height so that it can fit inside a selection of computer cases.

D15 weighs exactly 1000g and utilises a copper base and heat-pipes with aluminium fins which use soldered joints and nickel plating.





Noctua has given D15 recessed fins in the lower regions of each side to extend compatibility for memory kits which have tall heatspreaders. The profile of the fins follows a slight concave design.

D15 features six copper heatpipes which are responsible for transferring the heat from the base and out through the aluminium fins.



At the bottom of D15, there is a copper baseplate which is semi-transparent. On the topside of this base plate there is a mounting bridge - this bridge also has pre-attached screws with retention springs.



D15 comes with two NF-A15 PWM cooling fans which can be attached to either side of the dual-towers. Attaching a fan is very simple thanks to the metal clips which are bundled with the cooler, not only are they easy to fasten into place but they offer a secure fitment too.
