5 Best CPU Coolers For Ryzen 7 3700x – A Buying Guide

If you are a gamer or someone with knowledge about CPUs, you will know Ryzen Zen 2 CPU is a top choice! This CPU has eight cores and 16 threads. On top of that, you get a great build and performance.

Additionally, you get all these cool features at a reasonable price as well. So, what’s the issue here? These power-packed CPUs heat up quickly, and you need to cool the temperature to avoid any damage. What do we do now?  Enter CPU Coolers! (They are all you need)

If you’re looking for the best CPU Coolers for Ryzen 7 3700x, we have got you covered. Let’s jump in!

Some Tips to Buy the Perfect CPU Cooler

With the market gushing with options, selecting the correct CPU Cooler can be a tricky job. There are various things to consider, and specifically the features with which these CPU coolers come.

To make things a little short, I have a video here detailing some of the essential points to keep in mind before you spend your hard-earned money. Click on the link below to get enlightened. 

Got a nice idea about choosing the right CPU cooler? Yay, I hope so!

Now, for the people who would rather read to get a descriptive idea of these parameters, read on! 

CPU Cooler Type

The CPU coolers available in the market are broadly divided into air, closed-loop, or all-in-one coolers and, lastly, custom/ open-loop cooling setups. 

Air Coolers 

Air Coolers consist of metal heatsinks and fans. You can buy them in various shapes, sizes and, not to forget, based on thermal dissipation capacities or TDP. 

Open Loop Coolers

Open Loop Coolers are the most expensive options sold in the market; they are extremely complex as well. You might take some time to understand their nitty-gritty.

On the brighter side, Open Loop Coolers tend to provide top-notch results and cooling performance. 

AIO or Closed Loop Coolers

AIO coolers are also referred to as Liquid Coolers. These CPU Coolers are known for their low noise production while working at maximum efficiency. (specifically comparing to air coolers).

For AIO coolers, you won’t have to cut and fit custom tubes. Neither will you have to maintain coolant levels. 

They are even leak-resistant and extremely user-friendly when it comes to the installation part. The only negative is the requirement of the larger case since they need space for a radiator.

CPU Socket

Buying the CPU Cooler and not being able to fit it in your sockets would be such a  waste of money! To save yourself from this misery, almost always choose the cooler model which fits your CPU socket comfortably.

You can go over socket compatibility charts available online to get a clearer idea!


Just like your CPU Socket, the motherboard also plays a big role in CPU Cooler selection. You must look for a Cooler that fits your motherboard. You can check for the details using Motherboard compatibility lists on the internet.

Case Compatibility and Cooler Height

Case Compatibility, along with the cooler heights together, accounts for a perfect CPU Cooler fit. The amount of clearance for coolers will depend on the different PC cases. Make a note of the clearance required by your pick of coolers, or calculate the clearance from the case.

Once you have the desired value of clearance, go for the CPU cooler that fits these specifications.

Ram Compatibility

Standard RAM modules (up to 33 mm) are extremely compatible with almost all cooler models. The issue arises when the user goes for RAM with taller heat spreaders.

Some big cooler models will heat sink themselves, or the fan might overhang the RAM slots on a motherboard when used with RAM Modules of greater heights.

All in all, you should check the popular models and their tendency to overhang the memory slots.

CPU TDP (Thermal Design Power) and Overclocking

The CPU size and design make a lot of difference when choosing a CPU cooler. Generally, big coolers have better cooling performance. These CPU coolers would suit higher TDP CPUs and overclock.

What does overclocking mean, though? Overclocking is the tendency to make your CPU work faster than its stipulated limits. 

Similarly, lower TDP CPUs will work fine with low profile cooler models


How does noise become a factor here? Well, for starts, as a user, you will, of course, prefer to use a system that works quietly as possible. Cooling performance and noise-making are far more related than you thought. 

A cooler with extra performance headroom for the CPU will have fans with low speeds and less sound.  On the contrary, your CPU’s fully maxed-out cooler shall have fans with high speeds once the CPU is under load.

Keeping all these parameters in mind, you should choose a CPU cooler that matches your CPU’s TDP class, overclocking tendencies and acceptable noise production. 

PCIe Compatibility

Just like I mentioned the CPU slot and motherboard compatibility, PCIe compatibility is a crucial point too. Big coolers may tend to overhang the top PCIe slot. 

How do we figure this out, then? I have observed that the whole compatibility largely depends on the cooler size, top PCIe slot placement, and CPU socket location. 

One should look for compact CPU Coolers that would be compatible in all cases and don’t overhang the top PCIe slot.

So, these are the top factors to be analyzed while buying the best CPU cooler for Ryzen 7 3700X or any other processor for that matter! Next up, I have my personal top 5 CPU coolers to give you the best cooling performance all the time!
