Design issues with CPU cooling: Overcoming heat and throttling

Introduction

✨ The importance of proper CPU cooling cannot be understated. In this article, we will delve into the design issues that can lead to heating problems and throttling in CPUs. We will explore solutions to overcome these challenges and ensure optimal performance and reliability.

Design issues with the bracket and cooling block

🔎 One of the primary design issues is the Shape and elongation of the bracket and cooling block. Inadequate alignment with the die can cause uneven heat distribution, resulting in suboptimal cooling performance. This disparity calls for a more elongated bracket and cooling block, matching the shape of the dye and facilitating a better thermal connection.

Uneven distribution of forces on the die

🌡️ The uneven distribution of forces on the die poses another challenge. The shape of the dye contributes to this problem, as the current heat sinks struggle to create a sufficient bond with the dye. This issue is highlighted by the presence of areas where no contact has been made between the CPU and the heatsink compound. The consequences are concerning, leading to heating issues and potential performance degradation.

Heating issues and the need for a bigger cooling solution

🔥 Heating problems are inevitable when the CPU is pushed to its limits. Even under stock settings, intense workloads can cause the temperature to rise significantly. In such cases, a bigger cooling solution is often necessary. While it may seem tempting to opt for a quieter solution, it's crucial to prioritize cooling capacity, especially for high-end CPUs that generate substantial heat.

▶️ Pros:

• Enhanced cooling performance and heat dissipation for demanding workloads
• Reduced risk of performance degradation and throttling

▶️ Cons:

• Potentially increased noise levels due to larger cooling equipment

Problems with current heat sinks

❌ Current heat sinks are not always capable of adequately cooling the CPU due to the aforementioned design issues. Various articles, such as the one from Eagle's Lab, shed light on the limitations posed by the shape of the dye and its impact on heat sink performance. This reveals a prevalent issue in the market that needs to be addressed for optimal CPU cooling.

A potential solution: removing the ilm

✨ Removing the independent loading mechanism (ilm), which includes the bracket and the flap, offers a potential solution. By doing so, the ilm is raised away from the motherboard, creating more space for improved thermal performance. Several articles, including one from WCCF Tech, discuss the benefits of this approach.

Testing and results with washers

🔧 Experimental tests have been conducted to evaluate the effectiveness of this solution. By inserting washers between the ilm and the motherboard, the researchers were able to raise the ilm further, achieving better cooling results. Different washer thicknesses were tested, and it was found that a 1mm washer yielded the best temperature reduction, up to nearly 6 degrees.

Other articles addressing the same issue

📚 Several other articles have also highlighted the design and cooling challenges faced by CPUs. These resources reinforce the need for better cooling solutions and provide additional insights into overcoming the heating problem. The cumulative knowledge shared in these articles can guide users in optimizing their CPU cooling setups.

Overlapping dimensions of old and new sockets

✂️ The overlapping dimensions of the older socket H5 and the newer socket V0 have been identified as contributing factors to this issue. The minute 0.2mm overlap may appear negligible, but when considering the tolerances involved, it becomes significant. This overlap could be the reason some users initially experienced no problems while using an LGA 1200 standoff with the new socket but faced heating and throttling issues under heavy workloads.

Personal experience with heat and throttling issues

🔍 Personal experiences can provide crucial insights into the problem's severity. While not everyone may encounter heating and throttling issues, it becomes evident when pushing the CPU to its limits. Compiling or rendering tasks that utilize all CPU cores can raise the temperature to the point of throttling, even with stock Intel settings. The Linux operating system provides a glimpse of the throttling phenomenon when the CPU reaches its maximum temperature threshold.

Conclusion

💡 Proper CPU cooling is essential to prevent heat-related performance issues and maintain system stability. Addressing the design issues with the bracket and cooling block, as well as exploring potential solutions like removing the ilm, can significantly improve CPU cooling performance. By acknowledging the challenges and implementing appropriate measures, users can ensure optimal performance and longevity of their CPUs.
