Best AM4 Water Block – Top Rated CPU Water Blocks in 2021


Proper cooling ensures that you use your computer for hours together and load heavy programs without the fear of overheating. A CPU that does not have a good cooling system will face problems such as slowing down and ultimately shutting down due to the heat. 

AIO coolers are in-demand among budget shoppers but they are not suitable for frequent overclocking. They are not versatile either. This means that you will start facing issues after a point. Don’t worry, though. There’s another option we can explore. It’s called the CPU water block. 

Water blocks are suitable for gamers because of their efficiency and performance. If you have an expensive CPU and would like to make the most out of it, you should not ignore the benefits of water blocks. They are really good! 

But, of course, there’s always the trouble of choosing the best because there are so many on the market today. To make this easy for you, we have compiled the top rated ones this year. (And, we are positive, they will remain on top for a long time!) But, before that, we need to speak about compatibility.

Importance of Compatibility

Just like every other component in your CPU, water blocks come up with compatibility restrictions. This means that you cannot just pick out any water block and expect it to work for you. There are separate water blocks for AMD, FM2, A3+, AM4, and so on. Interchanging them will give rise to issues. Most often, they won’t even work! So, checking whether the water block you like will work with your CPU will save a lot of hassle. We advise that you specifically filter your choices based on your need and only then start comparing. 

In this article, we shall specifically speak about AM4 water blocks because they seem to be the most in demand.

BONUS – Will Intel Water Blocks Work with AMD?

Unless they are widely compatible, this is not possible. Compatibility is usually restricted to the processor and its versions. This is because the sockets on Intel are different from those on AMD. So, a water block that is designed for Intel will not work with AMD.
