For all the best non-liquid CPU coolers we have seen till now, V8 GTS by Cooler Master is one of our favorite not just because of its aesthetic robot-face like looks combined with a beautiful black color and red lighting but also due to its remarkable performance. At stock clock, while you throw load on your CPU, V8 will make sure to keep the temperature below 50OC. Similarly, at overclock while you play your favorite games like Valorant, Battlefield V or War Zone, you can keep your temperature in range of 73OC.

Although, with its all-aesthetic looks, new horizontal vapor chamber technology and good control of temperature, the noise factor is what we did not like. At stock clock and 7.5V supply, it produced 34 dB of noise but at overclock and 12V supply, the noise raised prominently to 57 db. Besides that, we found nothing in V8 GTS to complain about.

  • Paste: NT-H1 thermal Compound

NH-L9x65 is another best low budget CPU cooler by Noctua with a compact layout rather than normal tower or C-style design. Although, it does not reach to the level of NH-C14 and NH-C14s but still a worthy competitor. Noctua tried to prove a point that how a low price and low profile cooler can also meet the average cooling needs of any processor specially an i7 9700k.

It is a 65mm Cooler as obvious from the name and will fit LGA115x and LGA2011 version Intel processor. Moreover, the NH-L9x65 is also compatible with AMD CPUs due to the AM4 sockets. Likewise, it comes with a 92mm NF-A9x14 PWM fan, which is 14mm thick and can spin on SSO2 at 2250 RPM. The airflow is at 57.5 cubic meter per hour, lower than 30 CFM.

The NH-L9x65 may not possess too many features but it is one of the cheapest and best air cooler due to its 100% RAM compatibility. It has 95 x 95mm footprint, which complies exactly with Intel LGA115x socket. This means, there will be no trouble connecting it along chipset coolers, nor will it overhang RAM slots. Additionally, it sit very well in motherboard and does not block PCIe slots like many other coolers.

Although it is one of the best cheap CPU cooler but we will not recommend to use it at overclock or if you are planning to throw high load at your CPU. At stock load of i7 9700k it is able to keep to keep the temperature lower than 58oC but at overclock, while you play high-end games like Battlefield V the temperature may shoot to 82oC which is not good for the health of your CPU.

If you are looking for a cheap quiet CPU cooler that do not produce noise more than 25 dB at stock load and 36 dB at overclock and not planning to throw too much load on your CPU then Noctua NH-L9x65 is the answer to your problem. However, we will not recommend using it on overclocking with high load.

  • Fan speed up to 2250 RPM
  • Quiet cooler
  • Low price
  • Average performer
  • Not recommended for overclock enthusiasts

The most exciting feature of NZXT X and Z-Series is the CAM software suite, which allows you to observe different variables like temperature, RPM, noise level, and controls Fan speed, RGB lighting etc. NZXT did something annoying in this X63 model as the fans are no more controlled by LCS unit and CAM suite. You may need to connect them with motherboard or you will have to buy an extra CAM compatible FAN hub to control them.

After mounting it to your Intel i7-9700k and being done with the installation process, you are surely going to love the performance of NZXT Kraken X63. At default clock level and without putting any load on system, the temperature can smoothly be maintained below 24oC which will may go up to 57oC if you apply a 100% load. Kraken x63 will not disappoint you if you want to overclock your CPU at 5.1GHz. Moreover, it will keep the temperature below 70oC even at 100% load, which is a notable performance.

For audiophiles, NZXT Kraken X63 is one of the best budget AIO water cooler, as the noise level will not cross 35 dB mark even at overclock and highest load. The only time it may make noise is when the fans run at 100% or 2850 RPM. The CAM software will never allow for such RPMs unless you customize it manually.

Our final verdict on kraken X63 is that if you are not willing to have a giant casing nor you want to throw too much money in fans and coolers but still looking for good air cooler performance then NZXT Kraken X63 is the recommended CPU cooler from us.

If you want to play heavy games, develop software, work on high-end engineering applications or planning to overclock, your CPU is going to produce a lot of heat, which will not just affect the overall performance but also have a negative impact on life of processor and other devices.

Air coolers are easy to install, keep temperature moderate and does not take too much space in your casing.

Air coolers can be U-type/twin Tower air coolers or C-type air coolers. U-type are the most commonly used form with a vertical stack of fins, arranged in parallel to the heat base.

A TDP rating is assigned to both CPU and cooler. If the TDP rating of CPU cooler is less than processor, it will not able to execute the job of cooling processor. A recommended CPU cooler is one that has TDP rating either same or higher than TDP rating of your processor.
