This LCD screen changes the whole look of the AIO, and your system will get a complete makeover on the use of this.

Now let’s talk about cooling.

The three included Aer P 120mm PWM fans are not behind. They blow an insane amount of air to the aluminum radiators. Most importantly, the fans are almost dead silent even at their 100%.

Since the AIO uses Asetek 7th gen pumps, it is incredibly efficient and silent at the same time. It makes the whole AIO astonishingly quiet even at full loads.

When you’re buying an AIO, the top things to look for are thermal performance, design, and acoustics. It’s challenging to get to see such a mix of superb performance, ultimate silence, and gorgeous looks all in one AIO. If you have the budget, there’s no reason to skip the NZXT Kraken Z73.

2.   NZXT Kraken X73 RGB

The NZXT Kraken X73 RGB strikes an accurate balance between performance and price.

Notable highlights of the NZXT Kraken X73 RGB:

  • infinity mirror and ring LED on CPU cooler block
  • 3x Aer RGB V2 120mm radiator fans

It won’t be inaccurate to call the NZXT Kraken X73 RGB a little brother to the NZXT Kraken Z73. It inherits a lot of fantastic features from the Z73.

The NZXT RGB CPU cooler provides virtually the same performance and cooling. The top CPUs from both Intel and AMD are very easy to cool down and maintain a stable clock for this AIO. The NZXT Kraken X73 RGB continues to be a performance king in this aspect.

The other great features like the pump and fans’ silent operation, premium build, and outstanding efficiency all stay genuine here.

Also, don’t forget to check out the best noctua cpu cooler available in the market.

What’s different is the design.

Instead of featuring an LCD screen, this model goes for a circular infinity mirror with a ring LED strip. And it looks beautiful. Add the fact that the three included Aer V2 PWM 120mm fans have RGB lighting, and you get a perfect liquid cooler to make your gaming rig stand out in terms of look.

And the removal of the LCD screen also decreases the price, making the NZXT RGB CPU cooler an excellent choice for enthusiasts who prioritize performance over design. In this aspect, the liquid cooler is a serious value for money.

Another thing you lose here is the ability to control the fans via the CAM software. That feature is restricted only to the flagship Kraken Z73 and other Z-series models.

With no surprise, the NZXT Kraken X73 RGB easily passes through all the critical factors of an AIO with high marks. It’s the striking balance between high performance, beautiful design, and a reasonable price that sets this AIO cooler apart from the rest of the crowd. And if you’re an admirer of such, the NZXT Kraken X73 RGB should be your top choice.

The 2.36″ LCD screen is, of course, the main highlight. Anyone who uses this one will be in awe at how gorgeous it looks. The insane level of customizations takes that feeling further to the top.

Cooling performance is once again top-notch here. The AIO is capable of cooling down the best CPUs relatively quickly. It guarantees to perform a lot better than even the most aggressive air coolers.

You can monitor and control the fan speed, LED colors, pump speed using the CAM software. It is an intuitive software that provides excellent visual info on system stats and allows you to monitor performance.

The only thing to complain about is the absence of RGB lighting on the included radiator fans. But to me, the LCD makes up for that.

The AIO shares most of its features with the Kraken X63 mentioned above. The durable construction, infinity mirror design with ring LED, extremely low noise, superb thermal performance remain the same.

The main difference is the size. Instead of a 280mm radiator, you get a 240mm radiator. The size makes the NZXT Kraken X53 practical for most small PC cases, particularly micro-ATX and ITX cases.

If you’re a lover of great-looking AIOs, you would know that sacrifice is generally made on an AIO cooler’s exterior looks to trade-in for better performance when it comes to small coolers. Well, I guess that’s not a problem anymore, as the NZXT Kraken X53 excels at both.

The two included PWM 120mm fans for the radiators provide a surprising amount of airflow for the size and look fantastic. Together with the infinity mirror design on the CPU cooler block and the premium build, it elevates the looks of any gaming rig that it goes inside.

The latest Asetek pumps ensure high water flow through the 240mm radiator and, therefore, more heat dissipation. Overall it maintains a stable and solid cooling performance for its size.

The only gripe with this product is the same as any X-series NZXT CPU coolers, the CAM software’s inability to control the radiator fans. It seems like it’s a feature that’s only available to the more premium Z-series AIOs.

The best part?

One of the critical points of buying this AIO is its design. The fan-favorite infinity mirror design is present here, with a ring of LED around it. Together it gives a distinctive look to it.
