ARCTIC TP-3 thermal pad 100 x 100 x 1.0 mm

ARCTIC TP-3 thermal pad 1.0 mm

This ARCTIC TP-3 thermal pad measures 100 x 100 x 1.0 mm and is designed for builders who need to bridge uneven gaps between components and heatsinks. Its silicone-based compound with special filler delivers high thermal performance while remaining electrically insulating and non-capacitive for safe handling. The material also dampens vibration and can be cut to fit RAM, chipset, ICs, graphics cards, laptops or consoles. Buyers who require a firmer pad for easier installation should look elsewhere.

Installation demands and thickness limits

The pad’s extremely low hardness makes installation more demanding than typical thermal interfaces, so the user manual should be consulted before fitting. Thermal resistance decreases with thinner pads, and at 1.0 mm this single layer is optimised for minimal gaps rather than large height differences. Stacking multiple pads is not advised because it increases resistance and reduces the compression benefit that gives the material its conductivity. Users needing to fill gaps thicker than 1.0 mm cannot meet that need with this product alone.

Capacity for close-spaced chips and small surfaces

The 100 x 100 mm sheet provides enough area for several small dies or memory modules, and the soft compound conforms well to closely spaced chips with slight height variations. It comfortably handles typical GPU memory, VRM and chipset applications where a thin, compliant interface is required. The pad runs out of effectiveness when the gap exceeds its 1.0 mm thickness or when a rigid, high-pressure mount is needed, as the very soft material cannot sustain heavy clamping forces without excessive compression.
