The last thing you want is your computer crashing in the middle of any important work or a crucial point in the game. However, it becomes a second nature of your device if it tends to heat up fast and extremely. However, what causes this heating issue? For any computer, the primary reason behind the heating is how much load the processor and the other components take up, in order to run a specific task. For example, if you are mailing and working on MS-Word for hours, there will be hardly any difference in the temperature of your device. However, even half an hour of hardcore gaming can make it steaming hot. The problem is multiplied when the cooler is not up to the mark. There is always a cooling system or air cooler within the CPU so that the heat is diffused and your device gets up and running in no time.

The CPU Cooler For i7 8700k Buying Guide

When a gamer is ready to spend 100s of dollars or even thousands of it, to ensure their gaming station to be totally in shape and in compliance with the needs of the next-gen gaming, they do look out for better specs to run on their system. This is when it comes to the need for the best CPU cooler for i7 8700k. So, before buying the best CPU coolers, there are some compulsory points to be kept in mind, as mentioned below.

If the space for the triple-fan towering of the cascaded cooling system doesn’t exist, it will be hard to install the cpu cooler. So, ensure to check it on the motherboard before buying the new one. For a small system, big fans will be like a showpiece, rather than being used in the system.

Further, also check the card clearance of RAM and PCIe before buying cooler. The dimensions of a cooler fan should never obstruct the RAM or any other components, and if it does, it is not the right choice.

The requirement of the system can be higher or smaller for the cpu cooler for i7 8700k. For a normal gamer, low-watt CPU cooler will work covering less space and high RPMs and if vice versa, make a guess about the system requirement or from manufacturer website, get a system endurance estimate. 

Best CPU cooler for i7 8700k are available as liquid and air cooler, for the Intel (next-generation) and AMD systems. Ensure to read the specs and compatibility of the system before buying, for low and medium-range CPU; smaller fans work better.

Both are available for the CPUs. It totally depends on the CPU type, watt, and some other features, which cooler would be well-suited herein. They have their own pros and cons, and one should look upon the same clearly before buying. Do not forget to consider the cost.

When the system gets overclocked, they are highly prone to overheat, and it also requires more heat dissipation in a smaller time frame. So, in order to ensure the speed of the system’s clocking, there is a requirement of the efficient cooler (make a choice as per your requirement) so as to neutralize the immense heat within the system during gaming mode.

Check for the fan’s requirement and further look if your best air cooler for i7 8700k comes with fan size or the clearance space availability. In case it is less vertically but can fit components horizontally, one can think of buying cascaded fans.

Further, if there is the availability of space for the 280mm single-fan cooler, one needs to buy an only one-piece cooler and install that.

It may or may not exist but always look out for the feasible, cost-effective components for the system and ensure to buy the best cpu cooler for i7 8700k. The money factor will also lead to choosing in between the air or  liquid CPU cooler but remember, the air coolers even when they are cheaper, they make more noise and take more time for cooling.   

Also, look out if you wish to spend more on the LEDs and its customization options, better support over software, clearance, and mounting options, and see how much the coolers might cost.


The liquid coolers are nothing more than the combination of the core plate, parts and the radiator, fans, and the pipes. Talking of how it all works altogether, when the processor gets heated, the liquid present inside the cooler head, heats up too, and is further pushed towards the pipe, which flows to the radiator.

The liquid herein than flows through the radiator’s top-half, and as it moves, the liquid gets cooled down by the fan, and by the time it reaches the radiator’s end, it starts flowing back across the radiator bottom half and finally towards the other pipe. Once the liquid is reached to the pipe, it flows down back as the cooled liquid, towards the processor to cool it again. This is called the loop.

Varied reasons exist for one to pick the liquid AIO cooler than the Air cooler. They are of compact making and fit easily, help to provide excellent temperature, which can further outperform the air coolers. Apart from the same, they also run quieter, and there exists no background noise with the liquid cooler. So, with so many benefits at hand, liquid AIO coolers exist as the best.

If one notes the sound made by the cooler, one might find it quite distracting. Air-based model is likely to produce noise, but there are some of the models which come with different cases and the borders which absorbs the vibrations and also help to prevent the excessive noise which sometimes acts as a threat.


Final Verdict

Now that you finally have a head start toward shopping for the best cpu coolers for i7 8700k, we hope you can find the best match for your device that not only is efficient but also budget friendly too. However, do note that the quality is not compromised to fit your budget, as a cheaper product is likely to be damaged beyond repair sooner. Apart from the eight options mentioned here, you can choose others too but these are among the best, which are readily available in the market. These CPU coolers are elemental to keep your device up and running.
