Best Liquid CPU Coolers

Best Liquid CPU Coolers

Suppose! You are tired of your CPU overheating or don’t want to deal with your PC’s complications while gaming or working. It is not simple to find a perfect cooling solution, but we still have some options to resolve it.

A liquid CPU cooler has one job: to handle all of the heat generated by the CPU and keep the internals at nice low temperatures. Traditional computers use heatsinks, special metal blocks that rest on top of the CPU and facilitate airflow. Modern PCs use liquid cooling, which might sound counterintuitive, but it’s actually the most efficient way to handle heat. Essentially, cold liquid flows through tubes to keep the CPU temperature low, and multiple fans work together to push all the hot air out as exhaust.

Liquid cooling offers a number of benefits over air cooling, not the least of which is bragging rights and quieter operating temperatures. Check out the buying guide below if you find yourself with any questions- otherwise, let’s dive right into our top picks!

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.

Liquid CPU Coolers Features

Once you have a general idea of what you need out of your liquid CPU cooler, it’s time to start shopping. Pay the closest attention to these features:

  • Socket compatibility. CPUs come in a variety of form factors and plug directly into your motherboard, which acts as a socket for the CPU itself. Because CPU form factors are so specific and varied, they require that any liquid CPU cooler comes in the same form factor. The bottom line is that once you know what type of CPU socket your current motherboard and CPU use, you can buy a liquid CPU cooler built for the same socket type.
  • LED lighting. If you’re a fan of lighting up your PC case, we’ve got good news for you: most liquid CPU coolers come with LED lights so you can decorate the interior to your heart’s content. Lighting is purely a matter of taste, but if you’re into it, you might want to compare your lighting options.
  • Wattage. Like everything else in your PC, your CPU cooler draws power, and you’ll want to make sure that both your motherboard and power supply will work with the liquid CPU cooler you buy.

3. Noctua D-Type Premium CPU Cooler

Noctua D-Type Premium CPU Cooler

Noctua is a name I hadn’t heard a whole lot about so I was curious to take a closer look. What I found certainly impressed me and gave me plenty of food for thought. Take a look for yourself and see if you want to add it to your shortlist…

By controlling the speed of the onboard fan through the motherboard, you’ll have some interesting new functionality. One thing is for sure: if your fan is going faster than it needs to, then you’re wasting power. Wasted power means reduced performance which means slower processing speeds. When you put it like that, then it starts to make sense doesn’t it? By dropping from 1500 to 1200 rpm automatically, I think you can really optimize things and push your speeds up.

The fin-stack looks a little different due to its asymmetry. Rather than being purely for show, there’s a clear, practical reason behind it: room for more hardware. It ensures that the Noctua will clear more of the motherboard slots that can be blocked off when you invest heavily in cooling. That will enable you to add more processing and memory power to your tower without compromising on cooling capability.

  • Triple-fan with large surface radiator
  • LEDs Sync with motherboard software
  • Higher performance at a lower temperature
