Best CPU cooler for i7 8700k – Buyers review

Choosing the best CPU cooler for your i7 8700k is essential to keep your processor cool. The right choice can provide you with years of performance, while a bad one can result in hardware failure and data loss.

This post will help you decide which CPU cooler is best for performance. The coolers are rated on their performance, noise level, and compatibility. We also included a buyer’s guide to help you find the perfect fit for your needs.

Why do you need an air cooler

CPU air cooler is an essential part that helps to reduce processor temperature which results in increased GPU performance and can perform more tasks efficiently. The primary reason for choosing an air cooler is its price. It’s much cheaper to cool your graphics card with air cooling rather than water cooling.

Another benefit is the ease of installation, with no requirement for high maintenance or water level checking. You can even choose different colors fans for better looks and improve airflow inside the case at the same time.

Choosing a CPU cooler

Choosing the best cooler for CPU might be quite difficult because among too many air CPU coolers it is challenging to choose. So we made a list of the best coolers and ordered them according to performance and availability in the market.

CPUs come in three form factors: ATX, Micro ATX, and mini ITX where ATX has the largest size and room to accommodate multiple cooling fans and radiators (water cooling) while ITX offers limited options in this department. Another factor you need to be aware of is compatibility.

What are the best CPU coolers?

If you are ambagious by choosing between liquid cooler vs air cooler for intel i7 CPU. As each cooler has its own level in its performance like most of the tech experts suggest that water coolers for GPU are more efficient than normal air coolers. Some might not be compatible with the size of your case and others will steal space that you can utilize somewhere else.

As for the CPU cooler, we have water cooling, standard air cooling, and last but not least all-in-one liquid coolers which provide both features in a single package. But when it comes to the best CPU cooler for i7 8700k we will discuss all the best coolers for core i7 8700k.

Air Coolers VS Liquid AIO Coolers :

The choice between the two is actually a personal preference. Both have their advantages and disadvantages. If we talk about air coolers, they are usually cheaper than liquid coolers but take up more space in your case. You can add multiple fans to make sure you maximize airflow inside the case and improve performance further.

On the other hand, a liquid CPU cooler offers much better cooling capability at same noise levels when compared with air coolers because it uses water to dissipate heat from CPU or GPU which emits much less amount of noise and creates a better environment for working with the best graphics card.

Another thing that you need to consider while choosing an air vs liquid CPU cooler is compatibility issues because many cases do not support all kinds of coolers in market, so you need to make sure your CPU and case is compatible.

Best Liquid coolers for i7 8700k CPU

Liquid coolers come in two forms all-in-one or custom loops. All-in-one is made of one block which consists of pump, radiator, and fan whereas the custom loop is composed of multiple blocks called the pump, reservoir, tubing, water block/pump top combo, radiator(s), fans with shrouds. Both have their own advantages but choosing one only comes down to personal preferences.

Custom loops provide better cooling capability at same noise levels when compared with all-in-one coolers because they use water to dissipate heat from CPU which emits much less amount of noise and creates a better environment for working with graphic cards or verify sockets for best motherboards.

Although it is mentioned that you can use any kind of liquid cooler for your graphics card but if you are planning to use an AIO cooler it’s better to choose the one that is made of the copper base which will provide enough contact with GPU.

Since liquid coolers are meant for more serious gamers or PC enthusiasts who want to squeeze every bit of performance out of their chips, therefore they might not be suitable for everyone because they require higher maintenance and water level checking. You also need to make sure your case support radiators before choosing one.

If you cannot mount a radiator on top of your case then AIO liquid coolers are perfect for you because all-in-one liquid coolers do not require any special installation like custom loops that hang lower than the case’s width so the radiator can fit inside without any issues.
