Thermal pad Alphacool 12461

The Alphacool 12461 thermal pad is a grey heat-conductive interface material intended to improve thermal contact between electronic components and cooling solutions. The pad measures 120 x 120 mm with a thickness of 0.5 mm and is supplied as a pack of two. Its flexible formulation fills small gaps and surface imperfections to promote efficient heat transfer in compact assemblies and retrofit cooling setups.

Advantages

The medium-thin 0.5 mm thickness balances conformability and thermal path length, enabling close contact across uneven surfaces without excessive compression. The grey material offers stable physical properties across typical operating temperature ranges and is supplied in a two-piece pack for multiple uses or spare replacement. Its sheet format simplifies cutting to size for custom applications.

Suitable for

• CPU and GPU heatsink interface where a thin pad is required
• Memory modules, voltage regulator modules (VRMs) and power MOSFET cooling
• Small form-factor devices, embedded systems and compact industrial electronics
• Retrofit or replacement thermal interface between boards, heat spreaders and chassis

Key specifications

• Dimensions: 120 x 120 mm
• Thickness: 0.5 mm
• Pack quantity: 2 sheets
• Colour: Grey
• Weight (pack): approximately 0.033 kg

How to use

Clean both mating surfaces thoroughly to remove dust, oils and old thermal materials before applying the pad. Measure and cut the pad to the required shape using a sharp blade or scissors, then remove protective liners if present and place the pad on the component or heat spreader. Assemble the cooling solution and apply even mounting pressure to ensure full contact between the pad and surfaces. Avoid excessive compression beyond the design thickness to maintain thermal performance.

Usage recommendations

Store unused pads in a dry, dust-free environment away from direct sunlight. For electrical insulation requirements, verify the pad’s dielectric properties with the device manufacturer. Replace the pad if it shows permanent deformation, contamination, or reduced thermal contact during maintenance.
