Noctua NH-D15S CPU Cooler Review

Noctua NH-D15S Overview
The Noctua NH-D15S while being made for compatibility is actually a pretty large cooler. Its actual dimensions are 165 mm x 150 mm x 135 mm (HxWxD) and it weighs in at 980g. Noctua has outfitted this cooler with a single NF-A15 PWM fan that is made to sit in the center of the two heatsink stacks. The fan has a max speed of 1500 RPM, at that speed it will generate a maximum of 24.6 dBA.

The cooler features a dual-tower design with two heatsink towers extending up from the base. Both of these towers are made of aluminum. The big difference between this cooler and the NH-D15 is that Noctua has recessed the bottom fins on the heatsink towers. This gives you better clearance for memory.

Taking a look at the heatsinks we can see that there are six large copper heatpipes that come up into them from the base of the cooler. You have the ability to install a second fan on the front of the cooler.

At the top of the cooler we can see these heatpipes protrude out of the top of the heatsink towers. Also there are Noctua logos on each heatsink tower.

Taking a look at the heatpipes they go directly into the heatsink base, which should make for great heat transfer. The heatpipes are quite thick and are made of nickel-plated copper. In the below photo you can also see the recessed fins on the heatsink.

Looking at the heatsink base it is also made of nickel-plated copper. The base has no visible scratches or machining marks on it. This should make for great heat transfer with your CPU.
