Features to Consider When Buying i7-8700k CPU Cooler

If you are going to be using your i7-8700k at full capacity, then you need to invest in a dedicated CPU cooler to keep your processor running efficiently and without leading to system failure. If you are spending thousands of dollars on setting up a dedicated gaming station, then spending a few hundreds of a CPU cooler shouldn’t be a problem for you.

But, the problem arsis when you have to choose a CPU cooler, which out of all is the best one for? In order to answer that question, you need to consider the most important features of the cooler before making the purchase. So, let us go ahead and look at them in detail so you can choose the most suitable and powerful cooler for your system to enjoy maximum performance.

System Requirements

The very first thing that you need to consider is the system requirements. For this, you need to ask yourself, what are you going to be using the system for? If you are an average player or mainstream user, then a low power cooler with more RPM should be good for you. But if you are going to be overclocking your i7-8700k processor then you need a powerful CPU cooler like the ones mentioned above.

Type of Cooler

Secondly, you need to consider the type of cooler that you wish to invest in. As mentioned earlier, there are air coolers and liquid coolers available in the market at present. For average usage, air coolers are great, but they do produce a loud noise. On the other hand, liquid coolers perform better than air coolers when it comes to overclocking and heavy usage. Plus, they run quietly giving you the peace that you need to focus on your task at hand.

Overclocking

Make sure to check whether the CPU cooler will be compatible with overclocking or not. When system is controlled, it heats up quickly and the risk of overheating enhances significantly. Therefore, you need a cooling system that has a heat sink nearby the processor and dissipates heat faster.

Number of Fans

The more the number of fans, the better the performance. It is simple math but at the same time it also means more noise. Also, you need to check whether you have enough space to add a multi-tower cooler in your case or not. So, depending on your requirements and space available, you can invest in a single or multi-tower fan.

The Price

Lastly, everyone needs the money factor. You need a useful device that gets the job done but is also a cost-effective component for you to invest in. If price is an issue, then air coolers are more affordable as compared to liquid coolers but remember, they do make noise and take longer to cool down the system.

What Does a CPU Cooler Do?

A CPU cooler is a dedicated component which is added to the motherboard alongside the CPU to maintain the temperature according to the system’s limit. Different types of coolers are available in the market which uses various techniques to lower the temperature by improving airflow and dissipating heat in the surroundings.

Fans and liquid cooling systems

As mentioned earlier, there are two types of cooling systems commonly used by individuals. With the advancement in technology, cooling software is also added to the systems these days which allow the user to access the power tech of the components and efficiently use the systems cooling system. But the most common at present are;

  • Traditional Cooling Fan

The Air CPU cooling system is often referred to as traditional cooling fan as well. It consists of a heat sink which is paired with a fan. Both work side by side to dissipate heat into the surrounding air via air vents. In short, they help with the airflow to keep the CPU cool and efficiently working.

  • Liquid Cooling

Liquid CPU cooling system is mostly used by professionals to keep the system cool and working for long hours. They work similar to the Air Coolers but instead of using air, they run on chilled liquid which runs through small pipes and a heat sink to draw heat from the processor to a radiator dedicated on the system. Then the radiator releases the heat in the surrounding air and the process continues.

FAQ’s

What is the best CPU cooler for i7 8700k?

There are some great CPU coolers in the market, but if you are looking for the best one for the i7-8700k processor, then the Noctua NH-D15 is the best one in the market. The cooler comes with the dual tower 140mm fans, six heat pipes and quiet cooling efficiency with all black design paired with RGB lighting is a top choice for high-end gamers. With its high-end tech and PWM for automatic speed control, the CPU cooler is ideal for over clockers and silent-enthusiasts!

Why do I need a cooler for my CPU?

CPUs can heat up to 100-degree Celsius which affects the efficiency and stability of the processor itself and the components in the enclosure. This means that the performance of the CPU will be affected due to overheating. So, in order to lower the CPU temperature and protect the component from heat damage, you need to add a cooler to dissipate heat in the surrounding air and maintain the permissible operating temperature limit.

Does i7 8700k need a cooler?

Yes, Intel Core i7-8700k is a 6-core processor with 12 threads, 12 MB Cache, and 4.6 GHz of turbo frequency which makes it perfect for gaming. But the highlighting feature is the ‘k’ in the name which suggests that the processor comes with an overclocking feature which leads to additional heat.

Overheating affects the efficiency and performance of the CPU and since the processor itself doesn’t come with a cooler, therefore in order to dissipate the heat and keep the CPU cool during maximum usage, you need to invest in a cooler.

Final Words

When it comes to the Intel Core i7 8700k processor, there is no doubt that it is one of the best performing processors in the market in the market. But at the same time, its overclocking feature often leads to overheating issues which can be troublesome for many users.

Instead of waiting for it to ruin your processing experience or get damaged over time, investing in a top-rated CPU cooler for your i7-8700k processor is worth the investment. With a CPU cooler at your disposal, you will not have to worry about the performance. So, get yours now to improve the efficiency and stability of the system.
