NOCTUA NH-D15S Dual Tower CPU Air Cooler

Noctua does not give a particular TDP (Thermal Design Power) rating to the NH-D15S. They do, however, emphasize real-world performance and compatibility details on their website. They provide extensive information about which CPUs the cooler supports, including the potential for overclocking. Noctua stresses hands-on testing and confirmation rather than a theoretical TDP value. The NH-D15S is a performance-class cooler that can fit a broad spectrum of CPUs, from the high-heat-output, overclocking-intensive ones.

Yes, the Noctua NH-D15S also includes Noctua's fantastic NT-H1 thermal paste. It is an excellent thermal compound known for performance, ease in application, and long-term durability. Having NT-H1 in tow is an enormous advantage as it's one of the leading thermal pastes often rated top among the finest available, and by having it pre-applied, you forego money and hassle in terms of purchasing it separately. It offers maximum heat conductivity between CPU and cooler.

Noctua NH-D15S incorporates a PWM (Pulse Width Modulation) fan.  It includes one NF-A15 PWM fan, or you have the option of adding a second one. PWM fans provide smooth and automatic control over speed with respect to CPU temperature. This leads to a better balance of cooling power under demand and low noise when the CPU is under partial load. PWM is often used for its efficiency and responsiveness.

The Noctua NH-D15S is quiet renowned as well. Noctua concentrates on keeping it quiet by ensuring fan design, heatsink design, and heavy-duty construction. The NF-A15 PWM fan that accompanies it is designed for quietness even when running at high speeds. No full-load cooler can be entirely silent, but the NH-D15S is one of the quieter high-performance dual tower air coolers out there, given its outstanding cooling performance.

The NOCTUA NH-D15S includes the Noctua NF-A15 PWM, which has a reported RPM range. The fan can go as high as 1500 RPM, and it can go as low as 300 RPM. The fan speed is automatically adjusted based on the CPU temperature via the PWM signal. This makes the fan silent (low RPM) during light load, such as internet surfing or video watching, and more power-effective (high RPM) during heavy load, such as gaming and rendering. In addition, the fan is designed for airflow and noise for maximum performance.

Having the size of the Noctua NH-D15S enables you to know if the cooler will fit in your case or not, and if it will be compatible with other hardware pieces or not. The size of the cooler is 135mm (Depth) x 165mm (Height) x 150mm (Width). You'll need to cross-reference these values with your case specs and your RAM modules' height so you'll know if they're compatible or not. The NH-D15S has a very slight offset to its design to improve RAM clearance.

The Noctua NH-D15S being an air cooler does not include a conventional radiator as with liquid coolers. It includes two heatsink towers upon which the cooling fins are mounted. The height, width, and depth of the heatsink towers are very important factors to look at when it comes to compatibility with your PC case and other hardware. This is located on Noctua's official website.

The Noctua NH-D15S is an exceptional high-end double tower air cooler and "sufficient" for most purposes, including heavy CPUs and serious overclocking. It's basically a high-grade cooler, delivering excellent cooling performance. For serious overclocking or heavily high TDP CPU, though, an expensive high-end liquid cooler may be the way to go. Consider your particular cooling requirement and CPU.

Noctua does not provide a specific TDP or wattage figure. They focus on real-world testing and compatibility information. The NH-D15S is designed for high-end CPUs and dissipates plenty of heat. Check Noctua's website to locate CPU compatibility lists and cooling performance data to determine if it will work for you. They provide extensive testing data for various CPUs and configurations.

Noctua NH-D15S is a dual tower CPU air cooler. That implies that it is made up of two independent heatsink towers with cooling fins. This allows a huge increased surface area for the dissipation of heat compared to single tower coolers. NH-D15S is actually an offset build that is made in order to optimize RAM compatibility, a prevalent fault with dual tower coolers.
