Thermal pad Alphacool 12459

The Alphacool 12459 thermal pad is a 100 mm x 100 mm, 1 mm thick grey thermal interface material engineered for effective heat transfer between components and heatsinks. It is intended to bridge microscopic gaps and improve contact conduction where direct metal-to-metal contact is impractical. Supplied as a single pad, this thermal pad is compatible with a variety of cooling setups and is supplied in a ready-to-apply sheet format.

Advantages

This thermal pad provides consistent thermal conduction across uneven surfaces thanks to its compliant material and 1 mm thickness. The grey formulation indicates enhanced thermal conductivity compared with standard silicone pads, enabling reliable heat dissipation for components with moderate thermal loads. The full-sheet format simplifies trimming and placement for custom sizes and shapes while maintaining electrical insulation properties appropriate for many applications.

Suitable for

• Filling gaps between PCBs, chips and heatsinks
• Cooling modules in desktop PCs and workstation builds
• Thermal coupling of power regulators, MOSFETs and VRMs
• Electronic enclosures requiring improved heat transfer

Key specifications

• Dimensions: 100 mm × 100 mm
• Thickness: 1 mm
• Color: grey
• Form: single sheet / pad
• Electrical insulation: insulating pad suitable for most electronic applications

How to use

Before application, clean both contact surfaces of dust, grease and old thermal material using isopropyl alcohol and a lint-free cloth. Cut the pad to the required shape and size using scissors or a utility knife. Remove any protective film if present, align the pad over the component or heatsink, and apply firm, even pressure to ensure full contact and to expel trapped air pockets. Reassemble the device and verify secure mechanical mounting of the heatsink or enclosure for optimal thermal performance.

Usage recommendations

Use the pad for moderate thermal loads and where a compliant insulating interface is required. Avoid excessive compression beyond recommended mounting pressure to preserve thickness and thermal performance. Store unused pads in a cool, dry place away from direct sunlight to maintain material properties.
