High idle temps on x570 steel legend

Understanding High Idle Temperatures in Your PC Build: Insights and Solutions

When it comes to building and maintaining custom PCs, one of the common concerns among enthusiasts and casual users alike is the thermal performance of their system. A recent inquiry on Reddit brought to light a common question about idle temperatures in a four-year-old, yet still robust, gaming build. In this post, we will delve into the specifics of this particular case, exploring the components involved, potential reasons for high temperatures, and effective solutions to ensure your setup remains cool and efficient.

Meet the Build

Before we dive into diagnosing the problem, let’s take a closer look at the build components:

• Motherboard: ASRock X570 Steel Legend
• Processor: AMD Ryzen 5700X3D
• Cooler: Raijintec Orcus 360
• RAM: HyperX Predator DDR4 3200MHz (16GB x 2)
• GPU: ASUS TUF 3070 Ti
• Power Supply: Corsair HX 1200i
• Storage: Two M.2 SSDs (1TB & 2TB)
• Case: Hyte Y70 with optimally placed fans for good airflow

Symptoms of the Issue

After cleaning the PC and out of sheer curiosity, the user decided to monitor the temperatures with HWInfo64. The readings revealed elevated temperatures, particularly for the motherboard, Southbridge, chipset, and memory components:

• Motherboard Idle Temp: 45°C
• Southbridge Idle Temp: 57°C
• Chipset Idle Temp: 58.3°C
• Memory Idle Temp: 55°C

Under load, some of these components reach even higher temperatures, with the chipset and Southbridge maxing out at around 90°C, and the memory approaching 75-80°C. Despite these numbers, the system is reported to function without crashes or instability. However, the user expressed concern about the longevity and performance implications of these temperatures.

Analyzing the Components and Temperatures

Understanding the typical temperature ranges for each component is crucial in determining whether these reported temperatures are alarming or within a reasonable range.

Motherboard and Chipset Temperatures

Motherboards, particularly those equipped with X570 chipsets, are known for generating more heat than their predecessors due to several factors:

1. Built-in I/O Interface: X570 boards handle increased data throughputs, which naturally leads to higher heat generation.

2. Active Cooling Requirement: Unlike other chipsets, many X570 boards come equipped with small fans to manage temperatures. While helping, these fans can sometimes wear out or become insufficient.

Ideally, idle temperatures for a motherboard should reside in the mid-30s to low-40s°C. Therefore, the 45°C Reading is slightly elevated but within an acceptable range considering potential thermal inaccuracies and ambient room temperature variations. However, the Southbridge and chipset temperatures at both idle and load levels could be cause for concern.

Memory Temperatures

Memory modules, especially those like the HyperX Predator DDR4 with high frequencies, naturally generate heat. Typically, DDR4 memory may idle around 40°C to 50°C and peak up to 70°C to 80°C under intense load. The observed temperatures are high but believable, especially if the modules are not actively cooled or clean airflow is obstructed.

The Case of Elevated Temperatures: Potential Causes

Let’s examine potential reasons that could contribute to these elevated idle and load temperatures:

1. Dust Accumulation: Even though the user recently cleaned the PC, areas like small heatsinks or hard-to-reach motherboard sections might still harbor dust. This affects heat dissipation.

2. Ambient Room Temperature: Environments with higher ambient room temperatures can increase baseline PC temperatures across all components.

3. Thermal Paste Degradation: Over time, thermal paste between components such as the CPU and cooler can degrade, losing efficiency and resulting in higher temperatures.

4. Suboptimal Airflow: While fans are reportedly optimally placed, even slight obstructions in airflow pathways or fan malfunctions could impede heat removal.

5. Power Delivery and VRM Load: Reading a power reporting deviation of 80.5% in red might indicate an imbalance in voltage regulation. This causes additional thermal strain on motherboard components.

Potential Solutions and Best Practices

1. Thermal Management

• Reapply Thermal Paste: Consider reapplying thermal paste on the CPU. A high-quality thermal paste with proper application can significantly improve cooling efficiency.

• Dust Management: Routine cleaning, especially in tight and concealed areas, is important. Dust filters are recommended for case intakes to minimize future accumulation.

2. Airflow Optimization

• Fan Configuration: Double-check the case fan setup to ensure you have a good balance of intake and exhaust configurations. Using Software to adjust fan curves can optimize performance under varied loads.

• Cable Management: Neaten up cables inside the case to reduce obstructions and improve airflow.

3. Supplemental Cooling

• Memory Cooling: Consider adding memory heatsinks or fans designed explicitly for RAM cooling to maintain lower temperatures during heavy use.

• Additional Case Cooling: Explore additional case fans or upgrade existing ones to high airflow models if space and configuration allow.

4. Monitor Environmental Influences

• Control Room Temperature: Aim to manage ambient temperature through improved ventilation or conditioning.

• Evaluate Case Placement: Ensure the case isn’t placed in an enclosed or restrictive space, which would constrict airflow.

5. Component Monitoring and BIOS Updates

• BIOS Updates: Keep the motherboard BIOS updated. Manufacturers periodically release updates intending to enhance thermal efficiency or fan control algorithms.

• Regular Monitoring: Continually use Software like HWInfo64 to track temperature and voltage changes over time. Understanding how your system behaves under various conditions provides insights for further adjustments.

Conclusion

In essence, while the reported high temperatures for various components in this PC build are a potential cause for concern, they are not immediately dangerous, nor do they affect system stability at present. By implementing the outlined solutions and maintaining regular monitoring, this system should continue to operate reliably until the anticipated upgrade to newer hardware like DDR5 RAM. Regular maintenance and environmental control play significant roles in preserving your build’s thermal integrity, performance, and lifespan.
