Is your AMD Ryzen CPU Running to Hot? Here's how to fix it!
If you have an AMD Ryzen CPU that is running to hot, there are 2 main reasons for this:
1. Your CPU cooler is Broken
2. Your CPU cooler cannot handle the power of your CPU
The reason there are 2 possibilities is because if your Cooler is broken, it doesn't mater what you do, your CPU will overheat.
However if your cooler simply cannot handle the power output of your CPU, we can fix this by setting a TDP (PPT) Limit on your CPU.
What is the difference between TDP and PPT
From our testing we have found that there is crucial difference between TDP and PPT.
TDP: Thermal Design Power
PPT: Package Power Tracking
For starters, AMD does not use the term TDP, instead they use the term PPT.
TDP is a measurement of power directly from the CPU. If you set your TDP to 65W, you will get 65W to the CPU.
PPT is a measurement of power to the CPU Socket on the motherboard and not the CPU itself. If you set this to 75W by the time the power is passing through the CPU, you may only be getting 60W.
Now that we have the correct terminology, lets see how to set a PPT limit on your AMD Ryzen CPU.
- Start by heading to AMD's website and Download Ryzen Master.
- Once installed, Open Ryzen Master where you will be presented with the following window:
3. Open the advance view by Clicking "Advanced View".
4. Once the advanced View Opens, Select "Profile 1".
5. Once "Profile 1" is shown, select "Precision Boost Overdrive"
6. Change the PPT, TDC and EDC setting to the following values:
7. At the bottom of the window, click "Save Profile", then click "Apply".
8. PPT limit has now been set.
9. Unfortunately, Ryzen Master does not automatically open and apply these settings when you turn on your PC, make sure to open Ryzen master and select "Profile 1" anytime you need these settings applied.
In the bellow screenshot, we can see our temperature is now sitting at a comfortable 61-62C.
Under Full load, the system will reach its PPT limit of 75W, however if we look at the CPU power, it is only getting 56W. If you are after more Wattage from your CPU, just head back and turn up the PPT until this is satisfactory for you.
TDC and EDC are left at default values, TDC: 95, EDC: 140.
