How to apply heat dissipation silicone grease: hot topics and operation guides on the Internet in the past 10 days
With the continuous improvement of computer hardware performance, heat dissipation issues have become the focus of users' attention. Thermal grease is used as a heat conduction medium between the CPU and the radiator, and its application method directly affects the heat dissipation effect. This article will combine the hot topics on the Internet in the past 10 days to provide you with a detailed guide for applying thermal grease.
1. Data on popular cooling topics on the entire network in the past 10 days
| Ranking | hot topics | Number of discussions (10,000) | main focus |
|---|---|---|---|
| 1 | How to apply heat dissipation silicone grease | 12.5 | Comparison of heat dissipation effects of different application methods |
| 2 | Silicone grease brand performance test | 9.8 | Thermal conductivity and durability |
| 3 | Silicone grease alternative | 7.2 | Liquid metals and phase change materials |
| 4 | Misunderstandings made by novices on smearing | 6.5 | Dosage control and uniformity |
| 5 | Silicone grease aging replacement cycle | 5.3 | Performance degradation timeline |
2. Detailed explanation of the steps for applying heat dissipation silicone grease
1. Preparation
• Clean the CPU surface and radiator base (high-purity alcohol is recommended)
• Choose appropriate silicone grease (the thermal conductivity of mainstream brands is recommended to be ≥5W/m·K)
• Prepare application tools (squeegee/plastic card/finger cot)
2. Comparison of five mainstream application methods
| method | Operational points | Applicable scenarios | Heat dissipation effect |
|---|---|---|---|
| single point method | Place a pea-sized amount of silicone grease in the center | Intel LGA package | ★★★★ |
| cross method | Cross two thin lines | AMD Ryzen series | ★★★★☆ |
| scraping method | Scrape into thin layers evenly | Large cooling base | ★★★★★ |
| five point method | Symmetrically distributed five points | multi-chip processor | ★★★☆ |
| spiral method | Apply in a spiral from the center outwards | Experimental plan | ★★★ |
3. Key considerations
•Dosage control:The recommended dosage for 12th generation Intel CPU is 0.3-0.5ml
•Stress test:After applying, it is recommended to run AIDA64 to observe the temperature difference changes.
•Bubble avoidance:Use diagonal screw fixing sequence when installing radiator
•Cleaning cycle:It is recommended to replace the game notebook every 12 months
3. Answers to recent hot questions
Q: The thicker the silicone grease is applied, the better?
A: Wrong! Actual measurements show that the thermal conductivity is the best when the thickness is 0.1mm, but too thick will increase the thermal resistance.
Q: Is it necessary to preheat the silicone grease in advance?
A: The new silicone grease does not require preheating, but it can be appropriately heated to 25°C when the operating environment is lower than 10°C in winter.
Q: Is it possible to apply with fingers?
A: Professionals recommend using tools. Applying with fingers may cause uneven thickness (the error can be ±0.3mm).
4. Mainstream silicone grease performance ladder in 2023
| brand | model | thermal conductivity | Recommended scenarios | reference price |
|---|---|---|---|---|
| Thermal Grizzly | Kryonaut | 12.5W/m·K | overclocker | ¥89/1g |
| Noctua | NT-H2 | 8.9W/m·K | daily use | ¥39/3.5g |
| Arctic | MX-6 | 6.0W/m·K | office computer | ¥29/4g |
Through the above structured data and operation guide, I believe you have mastered the correct method of applying thermal grease. It is recommended to choose the appropriate silicone grease and application solution based on the actual usage scenario, and regularly monitor the CPU temperature changes to ensure that the cooling system is always in optimal working condition.
