How to Fix Heat Issues with Ryzen 7 5800x – Helpful Guide


Ryzen 7 5800x is 8 cores 16 threads AMD Zen 3 processor that was released on November 5, 2020. Over the last year, a lot of people complained about the problems they have with Ryzen 7 5800x.

The temperatures on Ryzen 7 5800x aren’t stable and may vary. Some people don’t have these problems but the majority of the people that have this processor face temperatures like 90°C or more in full load, which is hotter than the Processor that was released in 2020 should be.

Today I will try to help you out understand the problem you have and suggest to you the best way to lower temperatures.

If you are still deciding whether to buy Ryzen 7 5800x or not, I have some options that you should consider going for instead of the R7 5800x.

Are the High Temperatures Normal?

Although it’s an annoying thing to see in the games and heavy CPU usage, High temperatures are normal for Ryzen 7 5800x. Many people face the same problem with Ryzen 7 5800x when their CPU even passes over high 80°C and low 90°C which brings us to the conclusion that that is a normal thing for this specific chip.

As you can see in the photo below, This same problem has a lot of people and it’s one of the most commonly asked questions on forums.


Should you be worried about high temperatures on your Ryzen 7 5800x?

Actually, You don’t need to worry about this. According to AMD, high temperatures for high-end gen 3 Ryzen processors are normal, and won’t affect the lifetime of your components.

Take a look at the AMDs Robert Hallock, and what he says about temp issues.

Question: There have been many posts about thermals for these chips and I’ve read a few of your responses to them, as well as this graphic. Basically what you are telling us is that we have to change our understanding of what is “good” and “undesirable” when it comes to CPU temps for Zen 3, right? Cause I see you repeating the same info about how 60-90C is expected(i.e., where 78C may have been the top range, 90C now is, hence your statements about extra thermal headroom) and yet people keep freaking out because of what they have been used to, whether it’s from Zen 2 or team blue?

Robert Hallock’s answer: Yes. I want to be clear with everyone that AMD views temp up to 90C (5800X/5900X/5950X) and 95C (5600X) as typical and by design for full load conditions. Having a higher maximum temperature supported by the silicon and firmware allows the CPU to pursue higher and longer boost performance before the algorithm pulls back for thermal reasons.

Is it the same as Zen 2 or our competitor? No. But that doesn’t mean something is “wrong.” These parts are running exactly as designed, producing the performance results we intend.

Why is Ryzen 7 5800x running this hot?

Although we know that it’s normal from Ryzen 7 5800x to have such high temps, a lot of people don’t know the reason for that.

The Best answer on this Topic is coming from one Reddit user – You can find it Here

There is nothing wrong.

This SKU has the highest intensity of the whole Ryzen 5000-series line-up, it being a single CCD SKU with a 142W default power limit, the same power limit that is normally given to CPUs which have two CCDs (i.e. twice the area to transfer the heat out from).

On top of that, it seems that higher SIDD (static leakage) silicon is more commonly found in this SKU, which makes it run even hotter in relation to silicon with lower leakage characteristics, even at the same exact power dissipation.

TLDR: The CPU die is so tiny relative to the amount of power it dissipates (i.e. high intensity), that you cannot effectively transfer the dissipated heat from the die to the ambient air (through the radiator), no matter if you are using the best custom loop money can buy.

It’s physics and there is not much you can do about it. Improving the cooling helps to a point, but won’t change the basic behavior, that is the result of extremely high intensity and maybe partially the higher leakage characteristics of the silicon that maybe tends to bit a bit higher in case of this specific SKU.

What can you do to reduce CPU temperatures?

As I said before, high temperatures are normal for Ryzen 7 5800x and won’t affect your CPU lifetime. But there are a few things that you should do to decrease temperatures on your CPU as much as you can.

1. Clean your PC

Although this may sound absurd, cleaning the PC from dust can improve your PC’s performance and temperature much more than you thought. The process of cleaning the computer is easy, you will only need a compressor or some brush and a few minutes of your time.

2. Upgrade your CPU Cooler

The CPU cooler is a very important aspect of processor temperatures, especially with processors like Ryzen 7 5800x. There are a lot of good air coolers on the market right now. One of the best air coolers which have a reasonable price is Noctua NH-U12A.

This cooler will be super quiet and it will keep your CPU temp much lower than any stock cooler can.

3. Change your Thermal Paste

Sometimes thermal paste can play a big role in processor temperature. In order to get the best temps, I advise you to change your old thermal paste to some quality paste that doesn’t need to be expensive. I will suggest you one that I personally use, but you can use another one that is better for your budget.

I’m using the Noctua NT-H1 thermal paste. You can find it on Amazon for only $15.

4. Improve your Pc Airflow

The overall Airflow in your PC is important for the temperatures of all your components. When building the PC, it’s important to carefully choose the case and fans in order to get the best possible airflow.

Don’t Buy Ryzen 7 5800x – These are Better options

Although the Ryzen 7 5800x is a very good processor, temperature problems make a lot of people decide not to buy this CPU.

My suggestion for you is to avoid the Ryzen 7 5800x and go for either Ryzen 5 5600x or Ryzen 9 5900x if you can afford to spend some more cash. The risk to get the chip that has temps problems is high, so going for these two is actually much better.
