It is true that in the current age of intensive gaming, simply air cooling is not enough to satisfy gaming geeks. Air cooling is sufficient for simple tasks but for hectic and heavy gaming, liquid cooling is a better option that cools down the whole system in a matter of second. Moreover, for i7 12700K, a super-performer, we highly recommend a Best liquid cooler like Pure Loop 280 mm. Even during Peak CPU performance, the immense cooling performance of Pure Loop 280 mm will provide long durations of low temperature. The functionality of Pure Loop 280mm Liquid Cooler is similar to that of Corsair H100i Platinum SE Liquid Cooler and although Pure Loop 280 mm lacks an elegant RGB Lighting system, the decent default color scheme it comes in is still appreciable. Those who are not really fan of flashy color themes actually love the simple white LEDS Pure Loop has to offer.
Nevertheless, lighting is not the feature that Pure Loop 280 mm calls attention to. As you could tell from the name of the brand “Be Quiet”, the main emphasis in this product is enabling the user to have quiet, noise-free operation. This Cooler performs with as little noise as it is possible. Altogether, the company offers four sizes of 120 mm, 240 mm to 280 mm and 360 mm; all of these have same functions and perks to offer, they simply differ in the size of their radiators. Therefore, if you wish to buy Pure Loop Liquid Cooler, you have plenty of options to choose from; 280 mm is just the most popular one among these sizes which is why we will be covering it in this article.
As for the fans, Pure Loop 280 mm features Be Quiet’s very own dual 140 mm Pure Wings fans that are PWM supported. The rifle bearings of the fans are outstandingly noiseless. The 140 mm fans possess the highest speed among the series with top most speed of 1,600 RPM. The fans have total of 9 highly optimized blades that are ideal for the aluminum radiator of Pure Loop 280 mm.
With regard to the design of Pure Loop 280 mm, it can be said that it is fairly typical with cooling block mostly made of plastic. The all black design of Pure Loop 280 mm looks elegant with the contrasting white LED illumination. Pure Loop 280 mm looks magnificent in any system especially with its aluminum cooling block.
Another great characteristic of Pure Loop 280 mm is that the pump is separately located and not on the cooling block like most coolers. Therefore, when the block’s job is to exchange the heat between CPU and the cooling liquid, the pump is not exposed to immensely high levels of temperature and consequently lasts longer. Moreover, this unique position of the pump near to the radiator isolates it from rest of the cooling system and further eliminates unnecessary noises by blocking out micro-vibrations. The effective and useful damping by pump is one of impactful tactics used by Be Quiet to further enhance quiet operations.
Pure Loop 280 mm features several other characteristic that improves its performance. For example, in order to increase the efficiency of the cooler’s transmission of heat, the radiator fins are more compactly packed. Not only that but with help of a reservoir, the cooler allows a smooth and nonstop flow of liquid throughout the whole system which further improves heat transfer.
As far as the refiling of the coolant is concerned, the process is easy, comfortable and safe as the refiling port is easily accessible. Another great thing about Pure Loop is that a coolant bottle is already included in the packaging and thus it ensures even longer life span. Handling of the cooler has also been made very easy with simple mounting process and sleeved tubes that are flexible. It supports most prominent sockets like LGA1200, LGA1151 and AM4.
Conclusively, Pure Loop 280 mm is an ideal choice as one of the Best Quiet CPU coolers for i7 12700K as not does it give ultimate performance but it is noiseless and also ideal for price-conscious. It is best suitable if you play high-end and CPU intensive games like Cyber Punk 2077.

Things To Keep In Mind While Buying CPU Cooler For I7-12700k
Before you embark on your journey and start analyzing the products, it is important you take certain factors into consideration. You should be aware of your budget to avoid the effort of finding the right product and not being able to buy it. Other factors that you must give thought to are the fan type, socket type, the size of the coolers, the noise it produces, thermal design power and most importantly the compatibility.
Size of the Cooler:
There are number of coolers available for i7 12700K that are large and bulky in size with voluminous heatsinks and they require sufficient space to fit in. Nevertheless, these coolers provide ultimate cooling power but you should have a bigger case. However, if space is a problem and you do not want your PC to take up a lot of space, you should select a cooler that is not designed with tall cooling fins but rather possess slim ad low-profile ones.
TDP or thermal design power is one of the most crucial factors that you have to analyze before selecting a CPU cooler for your system. This determines the capability of your cooler, how much pressure of maximum amount of heat generation can your cooler bear or dissipate so the processor can continue to function without any hurdle even under immense workload. The combination of your processor and your cooler matters a lot here. It will prove very helpful if you select a cooler that has either same or more TDP rating compared to your processor. A higher TDP results in cooler being larger in size and possessing more cooling fins but it also gives results that are beyond one’s satisfaction.
There are types of fans that you have to choose from: would you rather prefer an air cooler or a liquid cooler. The difference between these two categories is that one uses cooling fans and heatsinks to eliminate heat form CPU whereas the liquid cooler utilizes water blocks as the name suggests. Although, air coolers are quite efficient at the job they perform; however, the problem with air coolers is that the fans disperse the heat right back into system which can cause a little rise in temperature. Liquid coolers, on the contrary, relocates the same heat but it moves it to outside of the system
The basic reason why not all CPUs support every type of CPU cooler is the CPU’s socket type which connects to the motherboard. Different CPUs support different socket. It is possible that you buy a CPU Cooler but later realize that the socket type is incompatible. Therefore, on your journey of building an ultimate PC, make sure you purchase a cooler that has a socket compatible with your CPU. Otherwise, your components will simply fail to connect and all your hard work will be to no avail.
In many coolers, there is this annoying noise that fans produce when they are functioning fast to their limit. This sound is not only unpleasing for the user itself but for the surrounding as well. Hence, make sure that you check the specification list of the cooler to assess the mentioned noise levels.
Additional factors that you have to stay conscious of are the usage rate of your PC. If your usage rate is high you will be indeed of a robust and a highly durable cooler. A competitive gamer needs a high-end Cooler as the rig is more burdened. Other than compatibility of socket and TDP, you should make sure that your cooler is up to mark with all the specification of the motherboard. Other than that, as far as price levels are concerned, most expensive air cooler can cost approximately $100 whereas liquid coolers are much more expensive.
