- Reliable cooling
Another waterblock is made up of Nickel-plated Copper and acrylic glass body. Phanteks Glacier C360a is an ideal liquid cooling waterblock for efficient heat dissipation in mid-range and high-end Ryzen processors.
This waterblock comes with a digital-RGB circuit that gives an elegant RGB look inside a transparent PC case. It’s made up of high-quality materials that are prone to higher temperatures and reactive liquids.
So far, we are quite impressed with the design and quality of this waterblock. Right in the box, you also get your hands on Black and Chrome Plate covers to match the outlook of waterblock with the rest of the components on your motherboard.
So next comes the performance of Phanteks Glacier C360a in relation to AMD processors. The temperature on this waterblock is not as impressive as the EKWB products. But there isn’t much cooling difference between this waterblock and the EKWB’s Quantum Magnetic model.
We used this waterblock with Ryzen 5800x CPU and temps were stable at 34 Degrees at idle and 64 Degrees under peak load.
Phanteks Glacier C360a waterblock is cheaper and is less than the $100 price tag. However, there are some issues with this block that we need to address here. Firstly, it comes with a 3-pin header for LED strip, making it incompatible with mobos that have a 4-pin header.
Secondly, it is a bit bigger in dimensions, which makes it a bit difficult to install on smaller motherboards.
Watch Out: While Acrylic is a strong material, at the same time it is brittle. Overtightening or putting too much pressure can result in stress cracks as mentioned by titanrig.

This is one of the cheapest yet reliable waterblocks to install on an AM4 socket CPU. Without putting a hole in your wallet, you are getting a waterclock that has a solid Copper base and has an Acrylic glass top. The copper base has a height of 3mm with a large water container to suck more heat from your CPU.
Also, the Diyeeni waterblock is compatible with previous AMD sockets as well. This is a great option to go with if you are tight on budget and need a waterblock to cool down entry-level to mid-range AM4 compatible CPUs.
A cheaper price tag means you won’t find any fancy RGB lights and software at all. However, if your sole intention is to get a low-budget AMD CPU waterblock that can just do the cooling job, then this might be the right choice to stick with.
Factors to Consider When Buying Waterblock for an AM4 Socket CPU
Now as you are well aware of the most reliable waterblocks for AM4 socket, it’s time to know some important factors before buying one.
On marketplaces, you’ll find hundreds of waterblocks that claim to be the perfect match for your CPU. However, you have to be careful in picking the most reliable waterblocks. One way to be on the safer side is to stick with a branded waterblock.
Some of the most trusted brands are EKWB, WaterCool, Thermaltake, Corsair, Alphacool, etc. Now, this doesn’t mean that the rest of the brands are not good. But the ones that we’ve mentioned here really give you the best bang for your buck. At least you get a sense of security when you go with branded waterblocks that are bought and reviewed by hardcore gamers and overclockers.
This is the second most important factor to look at in a waterblock. Not every waterblock is made for every CPU. There are some waterblocks that are universally compatible with both Intel and AMD sockets as well. However, most CPUs in the AMD series share the same type of mounting system, so the waterblock that you’ll choose will definitely fit on your CPU socket without any issue.
Material quality plays a great role in the life span and effectiveness of a waterblock. Look for a waterblock that has a copper base, this makes a waterblock anti-corrosive and allows more heat dissipation. Modern-day waterblocks have a Nickel-plated copper base for high-end performance.
Having RGB stips in a waterblock adds more aesthetic to your overall build. However, this is not something compulsory to go after. In the end, you need a waterblock to be better at handling more heat. The RGB part makes a waterblock a bit expensive as compared to a non-RGB waterblock.
Keep in mind that if you are going after RGB waterblocks, double-check the pin headers. Some waterblocks come with a 3-pin header that is not compatible with 4-pin header motherboards.
Concluding all, these were some of the best AM4 waterblocks to consider at the moment. If we have to pick from this list, then it would be the EKWB EK- Quantum Magnetic waterblock. Despite being an expensive option, it gives you the most value and takes liquid cooling experience to a next level. Also, the Nickel-plated Copper construct and Acrylic glass body make this waterblock the right candidate for hardcore gaming builds.
