What are Normal Idle Temperatures for the AMD Ryzen 5 5600X?
Under normal operating conditions, idle temperatures for the AMD Ryzen 5 5600X normally fall between 30°C and 45°C. The temperatures of these can vary based on such factors as cooling solution, ambient room temperature and system configuration.
Stock Cooler (Wraith Stealth): The stock cooler users often report idle temps in the range of 40°C to 55°C. However, the design of the cooler is optimized more for cost efficiency than thermal performance, and this is considered higher than ideal.
Air Cooler (Noctua NH-U12S, Cooler Master Hyper 212): Idle temps usually drop into a range of 32°C to 42°C when using a mid-tier air cooler and you have better heat dissipation because the thermal capacity is higher and the heatsink is larger. This is a great setup for the users that want to keep the system quiet while at the same time enjoy lower idle temperatures.
AIO Liquid Cooler (Corsair H100i, NZXT Kraken X53): Idle temperatures with an All-in-One liquid cooler are as low as 28°C to 35°C, and even lower with cases that have good airflow and optimal fan curves. It’s one of the most efficient ways to keep idle temps at their lowest as the liquid transfer and radiator do a good job of dissipating heat even at idle.
Idle Temperature Comparison Table
| Cooling Solution | Idle Temperature Range (°C) |
| Stock Cooler (Wraith Stealth) | 40°C – 55°C |
| Air Cooler (Noctua NH-U12S, Cooler Master Hyper 212) | 32°C – 42°C |
| AIO Liquid Cooler (Corsair H100i, NZXT Kraken X53) | 28°C – 35°C |
Other Factors that Affect Idle Temps
- Ambient Room Temperature: Higher idle temperatures by 3°C to 7°C are expected if your room temperature is above 25°C.
- Fan Curve Settings: Fan curves can be aggressive enough to lower idle temps by 2°C to 5°C, but at the expense of noise.
- Power Settings: Changing your system’s power plan from High Performance to Balanced can reduce idle temperatures by 5°C to 10°C.

Why Does My Ryzen 5 5600X Run Hot at Idle?
If your AMD Ryzen 5 5600X does not idle at a temperature you’re happy with, there are a few things that could be causing your CPU to run hotter than you’d like. And idle temps over 50°C are often a sign that something in the system has to be adjusted. The most common reasons are incorrect cooler installation, incorrect BIOS settings, or software related power management problems.
Here’s a comparison table for troubleshooting why your Ryzen 5 5600X runs hot at idle:
| Cause | Symptoms | Idle Temp Range | Solution |
| Improper Cooler Installation | Cooler not seated properly or poor thermal paste application. | 50°C – 65°C | Reseat the cooler and reapply thermal paste. |
| High Power Plan or BIOS Settings | High Performance power plan or high CPU voltage (around 1.4V). | 50°C – 60°C | Switch to Balanced power plan, reduce CPU voltage to 1.25V – 1.3V in BIOS. |
| Inefficient Fan Curves | Poor airflow due to unoptimized fan curves in BIOS or software. | 55°C – 65°C | Adjust fan curves to improve airflow, lowering temps by 5°C to 10°C. |
| Background Processes | Unnecessary background applications using CPU power (e.g., antivirus scans). | +5°C to 15°C increase | Close unnecessary applications to reduce CPU load and temperatures. |
User Experience and Solutions
- Power Plan Adjustments: Users on Reddit and the Linus Tech Tips forums report that changing from the High Performance to Balanced power plan dropped idle temps from 60 degrees to around 40 degrees. That means the CPU can be put to idle state and cause it to downclock to reduce power consumption.
- BIOS Voltage Tweaks: A user on Tom’s Hardware fixed their high idle temperatures (roughly 55°C) on the BIOS setting CPU voltage from 1.4V to 1.3V and got them down to 38°C. Updating to the latest BIOS version often helps with voltage related heat problems too.
- Improper Cooler Installation: On the AMD Community forums, multiple users found that their coolers weren’t seated properly and were reaching idle temps of around 65°C. Once they reseated the cooler and reapplied thermal paste, they saw reductions down to 35°C to 40°C idle.
How Can I Lower My Ryzen 5 5600X Idle Temps?
Reducing your AMD Ryzen 5 5600X idle temperature will help stabilize your system and lengthen its life if your CPU is idling over 50°C. Here’s your complete guide to lowering idle temps, with user experiences and expert advice about how to do it.
1. Reapply Thermal Paste
Thermal paste can degrade over time, and can lead to poor heat transfer. It can even lower idle temps by 5°C to 15°C by reapplying a good quality thermal paste.
- Step 1: Take the cooler off the CPU.
- Step 2: You will clean both the CPU and cooler surfaces with isopropyl alcohol.
- Step 3: Put a pea sized amount of thermal paste in the middle of the CPU.
- Step 4: Reseat the cooler securely.
2. Undervolt the CPU in BIOS
Undervolting is decreasing the voltage offered to the CPU with the result that power consumption and temperatures drop while performance doesn’t suffer. Users report that dropping voltage down to 1.25V or 1.3V or even 1.4V will lower idle temps by 5°C to 10°C.
- Step 1: When booting press Del or F2 to enter your bios.
- Step 2: Go to CPU voltage settings and lower manually to 1.25V – 1.3V.
- Step 3: Save changes and reboot.
3. Adjust Fan Curves
With fan curves, you can make sure your fans will kick up to speed as they get hotter. Fan curves can be tuned to lower idle temperatures by 5°C to 10°C
- Step 1: Use your motherboard’s fan control software or enter BIOS.
- Step 2: Set fan curve to kick in fan more aggressively over 40°c CPU.
- Step 3: Test for stability and noise.
4. Switch to Balanced Power Plan
If you can, go with using the Balanced power plan instead of the High Performance, which will stop your CPU from running at max clock speed when idle, dropping temps by 5°C to 10°C.
- Step 1: Click on Power Options in Open Control Panel.
- Step 2: Select Balanced power plan.
5. Optimize Case Airflow
But proper airflow in your case is important for cooling. If a building is too hot, it’s possible to lower overall temperatures by as much as 5°C to 15°C by adding extra fans or moving existing ones.
- Step 1: Verify that your fans are intake (front) and exhaust (front/top).
- Step 2: If you feel you need more fans then add them and make sure you have a balanced airflow setup.
