Noctua NH-D15S Multi-Socket PWM CPU Cooler

Manufacture # Noctua | Model # NH-D15S

The NH-D15S is an asymmetrical single fan version of Noctua’s award-winning flagship model, the NH-D15. Thanks to its asymmetrical design, the NH-D15S clears the top PCIe slot on most µATX and ATX motherboards. At the same time, the single fan setup and recessed lower fins guarantee 100% RAM compatibility with memory modules of up to 65mm height. Users who have sufficient room can also upgrade the cooler with either a 120mm or round 140mm fan on the front fin stack for further improved performance in dual fan mode

Features:

• Compared to the award-winning NH-D15, the S-version uses an off-set, asymmetrical layout and a single instead of dual NF-A15 fans.
• The NH-D15S provides 65mm clearance for tall memory heatsinks, making it compatible with most high end modules on the market.
• As many current motherboards have the top PCIe x16 slot sitting close to the socket, bigger heatsinks tend to block it. Due to its asymmetrical layout, the fin-stack of the NH-D15S is off-set towards the upper edge of the motherboard when installed in standard orientation.
• Complying with Noctua's AAO standard and featuring sophisticated aerodynamic design measures such as Flow Acceleration Channels, the NF-A15 has quickly built up a reputation as one of the best 140mm fans on the market.
• Using the supplied extra fan clips, the NH-D15S can be upgraded with either a second round-frame 140mm fan with 120mm mounting holes (such as the NF-A15) for maximum performance or a common 120mm fan (such as the NF-F12) for improving performance while maintaining compatibility with RAM modules of up to 45mm height.
• The NF-A15 premium fan supplied with the NH-D15S supports PWM for convenient automatic speed control through the motherboard.
• The NH-D15S can be made compatible with the older LGA1366 and LGA775 sockets using the optional NM-I3 mounting kit, which is provided by Noctua free of charge.
