[easyazon_image align=”center” height=”500″ identifier=”B01N16CAKN” locale=”US” src=”” tag=”bytebb-20″ width=”500″]


  • It has a pre-applied thermal compound
  • Equipped with voltage-regulated cooling
  • Excellent CPU cooling like NZXT Kraken
  • There is an onboard controller for the PWM fans


  • Fans are a bit noisy when working at 100 percent

The EVGA Close Loop Circuit (CLC) cooler is an AIO CPU cooler that will cool your CPU, as a result, it will not overheat. It has flow control software that lets you adjust the fans, pump, and RGB lighting. You can get the same in a Corsair Hydro series or ELITE CAPELLIX; both use the Corsair iCUE software. The fans can turn up to 2,400 RPM, as a result, they’ll push out air at a faster rate.

With such speed, you can do more intensive tasks on your CPU for longer periods, and it will remain cool. To help reduce operating noise, the fans have an indent at the center of their frames. The heat sinks on this EVGA CPU cooler have copper bases that allow it to conduct heat at a faster rate. That’s because Copper is a good heat conductor, and it absorbs heat faster and holds it for longer periods.

The cooling block of this liquid CPU cooler has sleeved tubes that prevent leaks during usage. This is a bonus compared to other liquid cooling solutions that don’t use these tubes. The pump has a USB connector that you can connect to the motherboard using a mini USB to 9-pin USB 2.0 cable. By doing this, you can control the pump and lights, as we’ve stated earlier.

For installation purposes, CLC 280 has the accessories that’ll get you running up and fast. Like other liquid CPU coolers, ensure your computer has room for the radiator. Mind you, the fans can get noisy when working at 100 percent, so it’s best if you have a closed computer case. For this reason, we give CLC 280 an 8 out 10 rating for design; 9 out of 10 for performance, cooling quality and noise levels.

You can confirm this if you play 3D games on a laptop for long hours, there is no doubt it will heat up, and you’ll hear fan noise. This can affect your CPU and the laptop itself, but this CPU cooler will prevent that from happening.

When we analyze in the next section, it will amaze you what this cooler can do for you. Compared to a low profile CPU cooler i9 9900k might need in some situations, this cooler is on a different level. The appearance adds pleasant aesthetics to your computer if you have an MSI motherboard. These motherboards have some red color, when combined with black, your PC will stand out.

Key Features To Know

The following are features of Dark Rock Pro 4 that makes it stand out from the remaining CPU coolers on our list. These are technical features, but we’ve explained them in plain English in order to prevent confusion.

– Silent Wings Pulse Width Modulation Fans

The fans have quality features that fit a high-end processor like i9-9900k. First, the fan blades have optimizations that enable the highest possible performance. Second, they have a speed switch that alternates the fan speed between three modes. These are medium-speed, high-speed and ultra-high speed with fan speed up to 3,000 RPM. Also, they have fluid-dynamic bearings and six-pole motors that help reduce vibration.

– High Air Pressure

The faster hot air can leave the heatsink; the better for your CPU. The design team behind this cooler knows this, and that’s why the fan has a design for high air pressure. It’s a funnel-shaped design located at the front of the fan. With this, dust will not enter the cooler, because this can be detrimental in the long run. Also, fresh air will come in faster and the heated air generated from your CPU will leave as soon as possible.

– High-performance Copper Heat Pipes

Most air coolers have between three and six heat pipes; this cooler has seven. Also, they are high-performance copper heat pipes known for their thermal efficiency. This has many advantages; first, copper is a good conductor of heat, so it’ll absorb heat faster. Second, it’ll retain this heat for longer periods, so while you work these pipes take the heat away from your CPU. By doing this, you’ll get the most out of your CPU, because the cooler ensures it operates at higher speeds.

– Enhanced Ram Compatibility

When a cooler obstructs your RAM sticks, it leads to an unpleasant experience that you did not expect. For this cooler, the cooling fins have airflow optimizations and cutouts. Both, combined, ensures you get the best possible memory compatibility. As a result, there is no issue with using your RAM sticks before and after installation. With this, if you have a fast DDR4 memory operation up to 3,200MHz, you can use it for a better computing experience.

– Quiet Operation Under Load

Some processor coolers will generate noise when working at 100 percent. With this cooler installed, irrespective of what you throw at your CPU, you’ll hear no noise. The fans play a role in this, and the design makes the cooler the perfect choice in two places. First, overclocked systems where the CPU goes more than the stock speed. Second, demanding workstations where efficiency is a requirement to get the job done.


The air and liquid coolers on our best list meet i9 cooling requirements. A cooler prevents i9 9900k from overheating, but not all have a universal CPU socket. For a quiet cooler even under heavy workloads, choose the Dark-rock cooler on our list. But if you prefer a liquid cooler, CLC 280 fits the bill, and it works like an NZXT Kraken. In the world of overclocking i9 9900k, NH-D15 from Noctua is the king of air coolers.
