2. Noctua NH-L9x65

Best Low Profile CPU Cooler


  • Excellent for small cases
  • Quiet
  • Compact performance
  • Cheap-looking fan
  • Fairly expensive compared to the Corsair


The Noctua NH-L9x65 focuses on compactness instead of overall performance. Due to it's small form factor the NH-L9X65 is perfectly suited to smaller cases and small form factor builds, which lack the case / motherboard space for a giant heat sink and fan. The cooler boasts small dense copper heat pipes with an aluminum heat sink, coupled with a high RPM fan to provide extra air flow due to the reduced heat sink size.


The Cooler is compatible with Intel LGA 1150 – 2066, and AMD: AM2 – AM4*. The NH-L9X65 measures in at 95 X 95 X 65 mm with a weight of 413g. The fan RPM range is between 600 and 2500 RPM, and the heat sink is constructed from aluminum and copper.


The Noctua cooler is the perfect upgrade over a stock Intel or AMD cooler for gamers who are limited on internal case size, due to it's extremely small form factor.

3. Corsair Hydro Series H100i v2

Best AIO Water Cooler


  • Fantastic cooling performance
  • Low noise levels
  • RGB lighting
  • A little more expensive than an air cooler, but you want that water cooled beast gaming pc, right?


The Hydro Series H100i v2 is an upgrade of the original H100 unit (which was excellent). The changes Corsair made to this cooler are minor, it now gives extra fine-tuning as well as much lower noise levels. The current model is fantastic as it incorporates two fans and a large 240mm radiator. Just like the previous Hydro Series, the H100i v2 is the best aio water cooler. The setup comes with RGB lighting to give your gaming PC additional cosmetics if you're into that sort of thing, if you're not it's optional.


The cooler is compatible with Intel: LGA 2066, 2011, 1156, 1155, 1151, 1150 and AMD: AM4, AM3, and AM2. The cooler’s radiator size is 240mm with an RPM of up to 2435. Besides, the cooler is designed from copper and aluminum materials.


The H100i v2 is a perfect AIO liquid CPU cooler, which is done for you in a closed-loop. Installation is no more complex than installing a CPU and fan heat sink. The H100i v2 is more expensive than an air cooler. But, it's not possible to obtain this type of thermal performance on air. Additionally, with the water cooler loop your machine should run a lot quieter than a CPU fan setup, coupled with the lower CPU temps which should increase the longevity of the processor.

4. Corsair Hydro Series H60

Best Single Fan Closed Loop Liquid Cooler


  • Outstanding performance
  • Affordable
  • Excellent entry-level liquid cooler
  • Single color pump LED
  • ​Not as good as other coolers in this price category


The Hydro Series H60 is a small and basic yet highly dependable CPU cooler designed by Corsair. The radiator of the cooler is made from aluminum while the cooler itself is furnished with a copper contact plate. The cooler does not require any refilling because it is a completely closed cooling system. In addition, the radiator utilizes a single 120mm fan as a way of heat dissipation.


The cooler is compatible with Intel’s LGA 2066, 2011, 1156, 1555, 1151 and 1150 as well as AMD’s AM4, AM3 and AM2. The RPM can go up to 2000 while the radiator size is 120mm. It has noise volumes of up to 28.3 dBA.


The Hydro Series H60 is undeniably the best liquid cooler in the market. It has proven itself to be a leading entry-level cooler when it comes to liquid CPU coolers. If you are migrating from an air cooler, you will notice temperatures lessening as much as ten degrees Celsius. Significantly low noise levels will also be realized. The cooler does not have wanting problems but is faced with stiff competition from other coolers in this price category. Nonetheless, you should fear nothing because the Corsair H60 has been tried and tested.

5. Thermaltake WATER 3.0 Dual Riing

Best Liquid CPU Cooler


  • Fantastic cooling
  • Incredibly quiet
  • Incredible RGB
  • Costly
  • G-Sync only

CPU Cooler Buying Guide

Choosing the right CPU cooler is a challenging task considering the various types of coolers in the market. In this guide you will learn about the tips to consider when shopping for a new CPU cooler, it's the same set of questions we asked and researched, and can now answer for you below.

Air vs Water Cooler

As previously outlined in this article, there are crucial differences between liquid and air processor cooling systems. Liquid CPU coolers are much more efficient while the air coolers are significantly cheaper. A liquid cooler is best-suited for the heavy overclocking, intensive applications and demanding games. Air cooling for CPU's is a much better option for most gamers due to the simplicity, reduced purchased costs.

Take away: If you're not going to overclock, then stick with an air cooler for your CPU. Weight up the performance increase from overclocking vs spending your cash on a better chip (it's less fun than overclocking, booo!).

Socket compatibility

Various sockets from AMD and Intel affect both the socket and the mechanism utilized in securing the cooler in place. It is common for most coolers to be compatible with the standard socket, but AM4 socket support is to some extent limited. Ultimately, Ryzen CPUs were invented a year ago, so the different aftermarket cooler developers should have had significant time to adjust to the new socket type. The most important thing to check is the version of the cooler you are purchasing is compatible with the CPU that you have, especially if you are using the Ryzen CPUs.

Is RPM important?

RPM denotes Revolutions Per Minute, and in simple terms, it outlines the speed at which the fan is spinning. Most users think that a higher RPM translates to much better cooling, but this is not always true because a faster spinning means more airflow on the basis of the fan size and heat sink size. For instance, a larger fan translates to a much better airflow even when using a lower RPM. It is essential to note that a large heat sink plays a significant role in heat dissipation. Above all, a lower RPM means that there will be less noise from the fan. 


If you plan on overclocking your processor and push it to higher than standard voltages to increase performance, then you should grab one of the water coolers mentioned above to disperse the additional heat. If you are planning to have a budget-oriented gaming PC and have no plans of overclocking it, you could focus on a silent CPU cooler or stick with the stock cooler that comes with the processor.

Sound levels

Numerous manufacturers are tirelessly working to develop silent CPU coolers and PC's. Typically the loudest component in a computer are the case, graphics card and processor cooling fans. Coolers with smaller fans are often louder than coolers with larger fans. The main reason for this case is that large fans will not spin as fast as the small fans to give the same cooling ouput, which makes them quieter. In this case, coolers with 120mm fans will generally perform louder than coolers with 140mm fans. CPU coolers with several fans can also spin at much lower speeds because there are much more fans functioning to keep the chip cool.

From the coolers we reviewed the Master Hyper 212 EVO was the best air CPU cooler. There is a reason why the company that develops this monster is called ‘cooler’ and the Water 3.0 Dual Riing from Thermaltake is the best liquid CPU cooler. The fact that it integrates quiet fans and superb performance makes it the leading liquid processor cooler.
