Buying Guide: Things to Consider When Buying a Liquid CPU Cooler  

Before purchasing a new liquid cooler for your CPU, there are certain things you have to take into consideration so you buy exactly what you need. Here are a few things to consider before you make a decision on which unit to buy:

  1. The most important thing to consider is compatibility. You have to be sure that the cooler will fit perfectly with your system’s case. This will entail looking at the size of your radiator before buying a cooling unit. The size of CPU radiators range from 120mm to 280mm in length. You can check for the exact or maximum size of radiator that will be suitable for your case by looking at the specifications outlined in the case. Furthermore, note the thickness of your radiator and decide if you intend to utilize a push-pull system. This type of system needs greater space since it utilizes fans on either side of the radiator, pushing air via one side and pulling it through the opposite side.
  2. It is also very important to take not of the size of the CPU. The reason for getting a CPU cooler is to make sure that your CPU is cool all the time. Hence getting a smaller CPU cooler for a larger CPU will not achieve the desired objective. Generally, if your processor is producing more heat, you also need a larger cooler. There is no point in getting a cooler that will not keep your CPU temperatures as low as possible.
  3. It is easy to get carried away by beautiful high-end liquid coolers which promise incredible performance and other interesting features during advertisement. However, the reality is that you must analyze and have in-depth knowledge of your needs before you decide to go for a premium liquid CPU cooler. Like every other PC component, there are entry-level coolers as well as certain high-performance models that come with a premium price. If you can afford it, it’s good. However, you have to consider if it is suitable for your present system and CPU usage. Do not be carried away with features like LED lighting or built-in fan regulator, which while they are interesting, are not the most important features to look out for. Rather, look for those that deliver the best performance for their prices. The prices are not a determining factor because you can get a cheap liquid CPU cooler which will deliver optimal performance on your CPU temperatures, especially if you are upgrading from an air cooler.
  4. Budget is another important aspect to consider. True, everyone will like to have a $2000 custom waterloop, but not everyone can afford it. Thus, you have to think about what you can afford. Even though air coolers are generally cheaper, All in one’s (AIOs) are getting increasingly competitive and you can get a very ideal cooler at an excellent price.
  5. The reliability of the CPU cooler is also a huge factor to consider before you buy one. Make sure that you read the features and specifications adequately before you make a decision. Liquid CPU coolers can experience a pump failure or develop a leak. Even though it is very rare for AIOs to experience a leakage, it is better to go for a CPU cooler that has features that will prevent a leakage or pump failure.
  6. Finally, consider the aesthetics of the CPU cooler you intend to purchase. This may not be very important if you are on a tight budget. However, it will look more appealing if you get a cooler that fits into your color scheme or has the configuration to achieve this.

Pick the optimal cooling system for your CPU

As we have discussed previously, you have to find the right cooler for your CPU. This means carrying out an in depth market survey to choose the best and most suitable CPU cooler.

Types of CPU Coolers and When to Use Them

Liquid cooling

Liquid cooling may conjure up a picture of hardcore gamers making use of those crazy designs. This is because liquid coolers deliver excellent performance at all times and may not be important for normal everyday use. However, the perfect CPU liquid coolers are made to be compatible with standard ones. The main principle behind the workings of liquid coolers is the principle of thermodynamics. This means that heat gets transferred from warm objects to cooler ones. Thus, the heat that is produced by the CPU is channeled to the water or cooling agent. This is where the heat is cycled within the liquid until the CPU gets cool. This is how other parts of the CPU such as microchips are cooled as they continue to generate energy.

Air coolers

Air cooling is the most common type of cooling CPUs. This form of cooling makes use of CPU fans because they are efficient and cheap. The fans are utilized along with a heat sink which is meant to adsorb heat parts of the CPU that produces energy. When heat is generated, the CPU fan removes the heat and provides needed ventilation. Most people prefer air cooling because they are inexpensive and have the capacity to handle tough processing.

Choosing the most suitable CPU cooler is largely dependent on your project needs as has been discussed previously. While obtaining a CPU cooler that possesses extra power is important, getting one that perfectly meets the demands of your rig is more important when picking a CPU cooler.

Air Coolers VS Liquid Coolers

Air coolers depend on two major components: the fan and heatsink. The aim of the heatsink, which is typically designed with high heat conducting materials such as aluminum or a mixture of copper and aluminum is to remove heat from the processor. However, there is a limit to the heat that can be absorbed by the heatsink before it is dissipated. The fan therefore functions to prevent the heatsink from overheating by continuously spinning to ensure that cool air continuously runs through the system.

Liquid heating on the other part has more parts than an air cooler: pump, radiator, hoses and fan. While air cooling depends on the proper circulation of air through the heatsink, liquid cooling utilizes a similar method, but uses liquid rather than air. The liquid coolant, which is mostly water, is circulated through hoses that connect the parts that need to be cooled. However, just circulating the water isn’t enough, which is why the liquid cooler has its own type of heatsink, a radiator. our top review best weather radio. To also prevent the radiator from overheating, the fan ensures that cool air runs through it at all times.

With regards to efficiency and power, liquid cooling beats air cooling hands down owing to the fact that larger volume of liquid coolant can be circulated faster and more easily. As a matter of fact, liquid coolers are 2-10 times more effective in transporting heat than air coolers. That said you do not need liquid cooling except your CPU is overclocked. Even for light overclocking, air coolers are still very effective.

Due to the lower cost of producing air coolers, they are generally cheaper than liquid coolers. With regards to convenience, air coolers are easier to install than liquid cooler, except you are an experienced user. Therefore, liquid coolers are only necessary if you have an extremely overclocked CPU or a cramped computer case.
