HY510 Grey Thermal Paste 10g/20g – CPU GPU Heatsink Compound

HY510 Grey Thermal Paste – High-Performance Silicone Compound for CPU, GPU & Chipsets

Keep your computer running cool and stable with HY510 Grey Thermal Paste by Fanmuran. Engineered for superior thermal conductivity, this silicone compound grease efficiently bridges the microscopic gaps between your processor and heatsink — dramatically improving heat transfer efficiency for CPUs, GPUs, chipsets, and laptop cooling systems. Available in both 10g and 20g sizes, it includes a convenient scraper for easy, mess-free application.

Key Features

• Superior Thermal Conductivity: Thermal conductivity coefficient >1.93 W/m-K — significantly outperforms standard silicone grease, helping your components stay cooler without needing a heatsink upgrade.
• Broad Compatibility: Ideal for desktop CPUs, graphics cards (GPUs), motherboard chipsets, and notebook cooling systems.
• Electrical Insulation & Moisture Resistance: Non-conductive formulation with excellent insulation, moisture-proof, shockproof, and radiation aging resistance properties.
• Wide Operating Temperature Range: Handles working temperatures from -30°C to 300°C, with instantaneous resistance up to 300°C — built for extreme conditions.
• Beginner-Friendly Application: Easy to spread with the included scraper. Even first-time users can achieve a smooth, even, paper-thin layer with no bubbles or impurities.
• Extends Component Lifespan: By maintaining optimal operating temperatures, this compound helps ensure stable performance and greater longevity for your PC hardware.

How to Apply

1. Clean the CPU or GPU surface thoroughly — remove any dust, oils, or old compound residue.
2. Squeeze a small amount of thermal paste onto the center of the processor surface.
3. Use the included scraper to spread the compound evenly.
4. Apply to the thickness of a sheet of paper — thin, even, and bubble-free.
5. Remount your heatsink and reassemble your system.

Application Tips

• Apply evenly with no impurities or air bubbles trapped beneath.
• Do not apply too thick a layer, and avoid overflow onto surrounding components.

Frequently Asked Questions

Q: What is HY510 thermal paste used for?

A: HY510 thermal paste is a silicone-based heat-conductive compound designed to fill microscopic gaps between a CPU or GPU and its heatsink. This improves heat transfer efficiency, helping your processor maintain stable operating temperatures during heavy workloads or gaming sessions.

Q: Is HY510 thermal paste safe for GPUs and laptop chipsets?

A: Yes. HY510 is non-electrically conductive and safe for use on CPUs, GPUs, motherboard chipsets, and notebook cooling systems. Its insulating, moisture-proof formula ensures it won't cause short circuits if applied carefully.

Q: How much thermal paste should I apply?

A: A thin, even layer approximately the thickness of a sheet of paper is ideal. Apply a small amount to the center of the CPU, then use the included scraper to spread it uniformly across the surface — avoid excess that could overflow onto surrounding components.

Q: How often should I reapply thermal paste?

A: It is generally recommended to reapply thermal compound every 2–4 years, or whenever you remove the heatsink for maintenance. If you notice rising temperatures despite good airflow, a fresh application of HY510 can help restore efficient heat transfer.
