Unique-Bargains Thermal Pad 200x400x0.5mm 1.5W/mK Blue

SKU CH-H9TQ-HC4RS

Soft silicone pad fills gaps between heatsink and component, conducting heat at 1.5 W/m·K across a 200×400×0.5 mm sheet

  • Improves heat transfer with 1.5 W/m·K conductivity
  • Fills gaps between uneven surfaces for better contact
  • Low-hardness silicone cushions and dampens vibration
  • Withstands operating temperatures from 50 to 200 °C
  • Large 200 × 400 mm sheet allows custom cutting

Gap-Filler Thermal Pad

This silicone pad measures 200mm by 400mm and is 0.5mm thick with a thermal conductivity of 1.5 W/mK. It bridges uneven surfaces between a component and its heatsink to improve heat transfer. The blue material withstands temperatures from 50 to 200 degrees Celsius. It also provides damping and cushioning thanks to its low hardness.

Simple Three-Step Installation

First, clean the component surface thoroughly. Next, peel away the protective plastic film from both sides of the pad. Finally, place the pad where thermal contact is required. The soft silicone compresses well to fill gaps. The main risk is selecting a pad thickness that does not match the specific gap, which reduces thermal performance.

Builders Needing Custom Shapes

This large sheet suits users who cut their own pads for memory modules, voltage regulators or small chipsets. It is not ideal for buyers who want pre-cut shapes for a specific GPU or CPU block. Anyone needing higher thermal conductivity than 1.5 W/mK should look at alternative materials. The single-sheet pack may not cover multiple large heatsinks.

Highlights

  • Improves heat transfer with 1.5 W/m·K conductivity
  • Fills gaps between uneven surfaces for better contact
  • Low-hardness silicone cushions and dampens vibration
  • Withstands operating temperatures from 50 to 200 °C
  • Large 200 × 400 mm sheet allows custom cutting

Questions about this item

How do I confirm the pad is conducting heat correctly after fitting it between the heatsink and the component?

After installation, monitor the component temperature under load; a drop toward the expected range shows the 1.5 W/m·K pad is bridging the gap as intended.

What does the package contain and is any extra film or adhesive needed?

The box includes one 200 mm × 400 mm × 0.5 mm blue silicone pad with protective film on both sides; no separate adhesive or additional materials are required.

Which thickness and conductivity version should I select for a 0.5 mm gap on a CPU or GPU heatsink?

Choose the 0.5 mm thick pad rated at 1.5 W/m·K; it matches the gap size and provides the specified conductivity for typical heatsink interfaces.
