– Two Cooling Towers With Six Heat Pipes

A notable feature of NH-D15 is the dual tower, designed for good heat dissipation. Most air coolers out there have a single tower; so they will not perform like NH-D15. These cooling towers ensure NH-D15 has more surface area for heat distribution. What’s more, they provide more airflow that allows your CPU to cool down before it overheats. All these features combined ensure that your CPU will get better cooling efficiency.

– Memory Compatibility in Single Fan Mode

The ability to use tall and short memory sticks is good news from any CPU cooler, and NH-D15 does not disappoint. But, it comes with a twist; you can use tall memory sticks while the fan is in single fan mode. These memory sticks should measure 64 millimeters; a feature of high-end memory sticks. However, in dual-fan mode, you’ll need a memory stick that has the standard 32 millimeters height. Either way, if you have tall or short memory sticks, this cooler will not prevent you from using them.

– Two Nf-A15 Pulse Width Modulation Fans

NF-A15 fan has zero noise levels and follows Noctua’s Advanced Acoustic Optimizations standards. It’s a premium fan, and you’ll only find it on a premium cooler like NH-D15. To make it more interesting, NH-D15 has two of these fans, and they can spin up to 1,500 RPM. Combined with aerodynamic design measures, CPU overheating is a thing of the past. Finally, they have Pulse Width Modulation that ensures their stability.

– SECUFIRM2 Mounting System

Noctua went the extra mile to ensure you get the best CPU mounting during installation. The SecuFirm2 Mounting System is world-class, and it’s known for its quality. Also, it’s safe to use, and it makes the whole installation process easy. Besides, it provides good contact pressure for your CPU and better heat absorption. That’s because the cooler will fit very well, but you should not tighten the screws too much.

– Wide Fin Stack and More Heat Pipe Layout

The fin stack in a CPU cooler is the biggest factor that determines how well it will allow heat to leave your CPU. That’s why Noctua ensures that NH-D15 has a wide fin stack having a width of 150 millimeters. This provides a large surface area for heat distribution, and it gets better. The heat pipes have spaces between them, so they provide uniform heat distribution. A combination of the wide fin stack and the heat pipes layout gives NH-D15 an edge over other CPU coolers.

Conclusion

This article explained the best CPU cooler i7 9700k can use for efficient cooling. If you don’t keep the temperature of your i7 9700k in check, it is susceptible to permanent damage. If you want a cooler with a good reputation, it’s NH-D15 from Noctua. But if you are a high-end gamer, it’s H5 Ultimate from CRYORIG.
