Specifications

How to Apply

1. Clean the CPU/heatsink surface thoroughly to remove old paste and dust.
2. Stir the compound well before use (a small amount of oil floating on top is normal).
3. Apply a small pea-sized amount to the centre of the processor using a syringe, scraper, or finger cot.
4. Seat the heatsink and spread evenly under pressure.
5. Reseal the tube after use and store at room temperature away from dust.

Safety Notice

Keep out of reach of children. If accidentally swallowed or in contact with eyes, ears, nose, or mouth, rinse thoroughly with clean water and seek medical attention if necessary.

Frequently Asked Questions

Q: What is HY510 thermal paste used for?

A: HY510 silicone thermal paste is used to fill the microscopic air gaps between a CPU, GPU, or chipset and its heatsink or cooling device. This maximises the contact surface area and dramatically improves heat transfer, keeping your processor cooler and running more efficiently.

Q: How much thermal paste should I apply to my CPU?

A: A small pea-sized dot (approximately 3–4mm) placed in the centre of the CPU is typically sufficient. When the heatsink is mounted, the pressure will spread the compound evenly across the heat spreader. Applying too much can actually reduce thermal performance, so less is more.

Q: Is HY510 thermal paste electrically conductive — is it safe for my components?

A: HY510 is a silicone-based compound that provides high thermal conductivity while remaining electrically insulating, so accidental contact with surrounding circuitry will not cause short circuits. It is also non-toxic, non-corrosive, and RoHS compliant, making it safe for use on sensitive electronic components.

Q: How long does HY510 thermal paste last?

A: When properly applied and sealed, HY510 thermal paste maintains effective thermal performance for several years under normal operating conditions. It is recommended to reapply when performing major hardware maintenance or if you notice a significant rise in CPU/GPU temperatures.
