1. Noctua NH-D15

The Noctua NH-D15 is one of the best dual-tower CPU coolers that you can buy right now and it replaces the NH-D14, which was the king of its time. High-quality fans are included in the box and you can have them both installed with each tower. You can even add a third fan for even better cooling.

The cooler features 6 heat pipes that are soldered onto a flat shiny surface. The fin stacks have been widened as compared to the older model. This allows the 6 heat pipes to have more space between them for better efficiency. The bottoms of the heat stacks have been cut away for better RAM clearance.

Our Pick

The Noctua NH-D15 CPU is a bit beefy but the same can be said about pretty much any air cooler. This is one of the best coolers that you can buy right now and it is highly recommended for the 8600K.

Inside the box, you also get low noise adapters that decrease the speed of the fan from 1500 RPM to 1200 RPM. You also get a splitter so both fans can be plugged into a single fan header. You also get some thermal paste from Noctua. You also get the mounting hardware that you will need.

Pros

  • Great RAM clearance
  • 6 heat pipes
  • 2 fans included
  • 3rd fan can be installed as well
  • Fans are PWM
  • Excellent thermal paste included
  • 6-year warranty

Cons

  • The cooler is pretty beefy

2. be quiet! Dark Rock Pro 4

The Dark Rock Pro 4 has a 250W TDP and is a massive air cooler. It comes in black so it will blend in with the rest of your build nicely. The cooler has 7 large copper heat pipes and 2 fans. The 135mm fan is supposed to sit between the towers while the smaller 120mm fan is supposed to sit on the side for better RAM clearance.

The installation process is relatively easy and a screwdriver is included with the purchase of the cooler. This is a magnetic screwdriver and is very long so that you can easily install the cooler in place. There are holes on top of the cooler through which you can pass the screwdriver and screw in the screws. The screws themselves are not small enough to pass through these holes so you will need to hold them at the mount while you pass the screwdriver through the hole in the top of the cooler.

Our Premium Pick

The Dark Rock Pro 4 looks great and has impressive cooling performance. This is a massive cooler but it can keep high-end CPUs cool and will allow you to overclock your Intel i5 8600K.

The cooler looks great and the cooling performance is impressive as well. All things considered, this is a very nice cooler for the 8600K that will keep the thermals in check and allow for overclocking as well.
