HM501 Conductive Thermal Paste Heatsink Compound for CPU GPU LED

Quick Introduction: Overheating components are the silent killers of electronics. The HM501 Thermal Conductive Grease is your first line of defence. Unlike standard white silicones, this grey compound is engineered with a blend of Metal Oxide and Carbon compounds to achieve superior thermal conductivity (>1.93 W/m-k). Whether you are reviving an old laptop, assembling a high-power LED array, or fixing a gaming console, HM501 ensures efficient heat transfer from the chip to the heatsink, keeping your device cool and stable.

Quality Advantage & Differentiation: Why choose HM501?

1. High Stability: Unlike cheap pastes that dry out and crack within months, HM501 is formulated to remain viscous and effective over long periods, even under continuous thermal cycling.

2. Safety First: It is Electrically Non-Conductive. This eliminates the risk of short circuits if you accidentally smear paste on surrounding components (capacitors or pins)—a crucial safety feature for beginners.

3. Wide Temp Range: Capable of withstanding spikes up to 280°C, making it suitable not just for PCs but also for automotive electronics and industrial power inverters.

Key Applications & Usage

• PC Maintenance: Re-pasting old CPUs and GPUs to lower idle and load temperatures.

• LED Lighting: Essential for High-Power COB LEDs (10W-100W) to prevent burnout.

• Power Electronics: efficiently cools MOSFETs, IGBTs, and voltage regulators in power supplies.

• Game Consoles: Fix loud fan noise on PS4/PS5/Xbox by replacing the factory thermal compound.

What's Included & Required

• Included: 1xTube of HM501 Thermal Grease.

• Required: Isopropyl Alcohol (for cleaning old paste), Lint-free cloth or tissue.

• ⚠️ APPLICATION WARNING:

  • Less is More: Do not over-apply. A layer as thin as paper is ideal. A thick layer actually blocks heat transfer.

  • The "Pea" Method: For CPUs, place a single pea-sized dot in the centre. The pressure of the heatsink will spread it evenly without air bubbles.

  • Surface Prep: You MUST clean both the CPU and Heatsink surfaces completely using Isopropyl Alcohol (IPA) before applying new paste. Old residue will ruin performance.

• Troubleshooting: High Temps after application?

  1. Check mounting pressure (screws should be tight but not overtightened).

  2. Check for "Too Much Paste" (excess spilling over edges).

  3. Check for "Plastic Peel" (Did you remove the plastic film from the bottom of the new cooler?).
