Best CPU Liquid Coolers: Best AIO CPU Coolers for 2024

The Best Whiskey Glasses of 2024


AIO (All in One) water cooler is a fully integrated heatsink with today's CPUs, especially for overclockers. AIO is a good choice when choosing to buy a CPU cooler for overclocking to improve performance and limit CPU overheating. Don't miss the article below, let's look at the top 4 best AIO CPU liquid coolers of this year.

Buying Guide

AIO water coolers have a lot of parameters, but the most important one that you need to pay attention to is the size of the radiator. Radiator size 120mm, 240mm and 360mm are the 3 most popular sizes today. Fit with most medium tower cases on the market, depending on the space and cost you choose, there are some ground rules:

  • Large radiators dissipate heat more efficiently but take up a lot of space.
  • Large heatsink with more fans, you can run the cooling fan at a slow speed while still dissipating heat and reducing noise.
  • Put the exhaust fan in the box or blow the air out if you arrange it properly (for example, 3 exhaust fans – 3 blowers). If you are not familiar, it is best to install a fan to blow hot air out.
  • Most AIO heatsinks of major brands have software that allows you to control the pump speed and fan speed. You should learn to customize the parameters to suit your computer.
  • Make sure you can turn off RGB. RGB LED can be a fun way to customize the look of your PC, but make sure there is a way to turn it off without having to turn off the PC because there will be a time when you feel it is flashy and flashing like a child's toy.
  • If you own a Ryzen CPU? then you may not need the cooler. Because all current Ryzen processors and some older Ryzen models come with a built-in cooler and are fully overclockable. If you want the best possible CPU clock speed, you'll still want to buy an AIO cooler. If you are a basic user then that will not be necessary.


1. How long can I use an AIO Cooler?

The lifespan of the AIO Cooler depends on your computer usage and product type. However, AIO life expectancy varies between 4 – 6 years

2. Is there any maintenance required when using an AIO water cooler?

The only part you must maintain in an AIO, is the radiator and fans. This is because a lot of dust can get stuck inside or in between the radiator and the fans. You don't need to maintain the pump, or the liquid- it's closed and cannot be opened.

3. Do AIO Cooler come with liquid?

Yes, they come with a water-glycol mix. You generally cannot open them and add water. They are nearly always a completely closed system and not user-serviceable

4. Should I use an AIO cooler or an air cooler?

Just as a swimming pool cools you down quicker than a fan, AIO coolers are much better at chilling CPUs than air. This allows you to get the most out of more powerful components because you can overclock your processor to make it faster without temperatures rising too high.

Final Words

If you want a CPU Cooler that doesn't make too much noise, then an AIO Cooler will be the best choice for you. AIO will include all the necessary parts that you can set up without the need for too much knowledge of the water-cooler. Good performance, low noise, moderate price, durability is what you will get if you own an AIO CPU Cooler.
