How to Lower Ryzen 7 3700X CPU Temps

Perhaps your Ryzen 7 3700X is running a little hotter than you’d like. Maybe you’re noticing lower performance resulting from higher temps. This might have you wondering how to lower these temps?

There are different solutions to lowering CPU temps, some are simple, some a little more complicated. Below, we’ll be explaining different ways on how to lower Ryzen 7 3700X CPU temps.

Changing Thermal Compound

Thermal compound (or thermal paste) is the stuff that goes between the IHS (Integrated Heat Spreader, or the top of your CPU) and your CPU cooler. It improves the transfer of heat from your CPU to your cooler by filling in any gaps between the two surfaces since neither surface can ever be perfectly flat.

While higher quality compounds advertise that they can last for over 5 years on a single application, it is recommended to change your thermal compound whenever you see a noticeable increase in temps. Usually, this is around every 2 years for most applications.

Applying Thermal Compound

If you’re still using the stock paste that came on your Ryzen 7 3700X’s Wraith Prism cooler, you should definitely be changing it out for better quality paste. AMD’s stock thermal compound tends to dry out quickly and lose it’s thermal conductivity rather fast.

Going from the stock compound to a more quality option like Arctic’s MX-4), Noctua’s NT-H1, or Thermal Grizzly’s Kryonaut can net you up to a 5c decrease in temps over the stock thermal compound.

How to Reapply Thermal Compound

For our guide, we will be using the Ryzen 7 3700X’s Wraith Prism as an example. However, your cooling solution may vary, so it’s always best to consult the manual on how to disassemble. Aside from disassembly and reassembly, however, the steps will be the same for practically all CPU coolers.


Step 1: Removal of CPU cooler

Locate the lever that holds the cooler on. Unlock this lever, this should loosen the latches holding the cooler onto the motherboard/CPU.

Once the latches are loosened, unclip them from the tabs that hold them on. Don’t forget to also unplug the fan wire and RGB wire from the motherboard

Now twist the cooler gently to make sure it is not bonded to the CPU. Trying to pull the CPU cooler out without first making sure it is free from the CPU can result in damage, so be careful.

Once you have made sure the CPU cooler can be removed freely, take it off of the CPU and set aside.

Step 2: Cleaning

For cleaning of both the CPU and CPU cooler, you’ll need the following:

  1. Medical Grade Isopropyl Alcohol at 70% solution or higher, with no added perfumes or moisturizers
  2. Toilet paper or paper towels

First, take a dry piece of toilet paper or a paper towel and wipe as much thermal compound off of both the CPU and CPU cooler as possible. It is best to leave the CPU in the motherboard during the cleaning process to avoid damaging pins while cleaning.

Next, take the alcohol and lightly dampen some toilet paper/paper towel and wipe any remaining compound off. This may take a few passes to get everything off.

Once all thermal compound has been removed from these two surfaces, wipe once more with dry toilet paper/paper towel.

Step 3: Application of new thermal compound

Now that the CPU and CPU cooler are clean, it’s now time to apply fresh thermal compound. Make sure that your CPU/motherboard is laying flat during the application.

Take your thermal compound of choice, and apply it in an X pattern on the surface of your CPU, with each line of the X going from one corner of the square IHS to the other.

Now onto re-mounting the cooler.

Step 4: Re-mounting the cooler

To remount the cooler, line up the mounting holes on the latches with the tabs on the mounting bracket and make sure they are securely in place.

Once lined up, tighten the latches back into place by flipping the lever back to the locked position. Be sure to reconnect the fan cable and RGB cable for your cooler.

That’s it, you’re done. Lower temps and better performance await you.

Making Sure Your Case Has Adequate Airflow

No matter how good your CPU cooler is, you’re not going to be able to take full advantage of its capabilities if your case lacks proper airflow. A lack of good airflow can restrict the performance you’d expect out of your Ryzen 7 3700X due to high temps.

Most decent modern cases have multiple places to install cooling fans for adequate airflow. We’d recommend at least 2 intake and 2 exhaust fans to achieve optimal cooling.

Large window fan for adequate airflow

If your case doesn’t have enough fan mounts to make this possible, you may want to consider upgrading to a better case. Ideally, you want a case with enough fan mounts, enough expansion slots to fit your needs, and a mesh front to aid with proper airflow and cooling.

Our recommendations for this would be the Corsair 275R Airflow Edition or Phanteks P400A Mesh.

A Better Cooling Solution

If the stock cooler still isn’t enough, you may want to consider purchasing a better cooler for your Ryzen 7 3700X. A better cooler will mean lower temperatures, better performance, and more overclocking headroom if you so prefer.

While the stock cooling solution may be enough in some cases, it can run a bit hotter than you might like. We’d recommend changing to an aftermarket cooler to improve temps.

Though worry not, you don’t need to spend too much, even a cheap Deepcool GAMMAXX 400 will provide a significant temperature reduction over the stock cooler.

For those who want a more elegant solution, the be Quiet! Pure Rock 2 offers sharp looks and great performance.

And for outright best cooling, you may want to consider a liquid cooler. Something like the Cooler Master ML240L V2 RGB, or Corsair H100i would be an excellent choice to keep your temps low and your Ryzen 7 3700X running at its peak.

Reducing Your Ryzen 7 3700X Power Limits

This method is more of a last resort to the problem of “how to lower Ryzen 7 3700X CPU temps”. It is a bit more advanced and requires changing settings in your motherboard’s BIOS. By limiting how much power your Ryzen 7 3700X can draw, you can lower your temps.

Though this method will come with a performance decrease as well since you are limiting how much power your CPU has to do computations.

Below we’ll walk you through it with a step-by-step guide. We’ll be using an MSI B550-A Pro, and an MSI BIOS, to walk you through it, but the steps should be similar on other manufacturers’ BIOS.

First things first, we need to enter the BIOS. This is done by spamming the del button on your keyboard right after pressing the power button to turn it on (or after restarting). Once into the BIOS, you should be greeted by this screen

MSI Click BIOS Screen

Once into the BIOS, you’ll want to press F7 to enter Advanced Mode, it will take you to this screen

MSI Click BIOS Advanced Mode Screen

Navigate to the OC tab using either the keyboard or mouse. You will be greeted by the following options

MSI Click BIOS OC tab Options

Navigate to the “Advanced CPU Configuration” Menu

MSI Click BIOS Advanced CPU Configuration Menu

Then open the “AMD Overclocking” Menu

MSI Click BIOS AMD Overclocking Menu

Now you’ll want to change the “Precision Boost Overdrive” option to “Advanced” as shown below

MSI Click BIOS - Changing the Precision Boost Overdrive option to advanced

Once set to advanced, new options should show up below. You’ll want to change the “PBO Limits” to “Manual” like this

MSI Click BIOS - Changing PBO limits to manual

Finally, on the newest set of options, set “PPT Limit [W]” to 60w

MSI Click BIOS - Setting PPT limit to 60W

After this, make sure to press F10 to save and reset.

You can change the PPT Limit higher or lower depending on your temperatures. Lower settings will offer lower temps but at the cost of lower multi-thread performance, higher settings will give your CPU more multi-threaded performance, but will also increase temps. 60w is a good starting point for the Ryzen 7 3700X.

We have a report discussing whether the stock cooler for the Ryzen 7 3700x is good enough or not which you may find helpful.


Having gone through multiple ways of lowering temps on your Ryzen 7 3700X, we hope that at least one of these methods proves useful to you. We’ve done our best to provide what we think are the best solutions for your temps.
