Thermal pad Alphacool 12196 25 g Grey 30x30x3 mm

The Alphacool thermal pad 30x30x3 mm is a pre-cut grey thermal interface material intended for improving heat transfer between electronic components and heatsinks. Supplied in a 25 g package, this pad fills microscopic gaps and uneven surfaces to reduce thermal resistance and support stable cooling performance in compact assemblies. Its size and 3 mm thickness make it suitable where a thicker interface is required than standard thin pads or thermal paste.

Advantages

This thermal pad provides consistent thermal contact without the need for liquid compounds, offering easy handling and reusability in some applications. The pad’s uniform thickness and compliant structure ensure reliable surface coverage and pressure distribution, which helps maintain efficient heat flow. Being pre-cut to 30 x 30 mm simplifies installation and reduces trimming time for standard small components.

Suitable for

• Cooling of small chips, power transistors and VRMs in compact electronics
• Heat transfer between circuit board components and heatsinks or chassis
• Applications requiring a 3 mm gap-filling thermal interface

Key specifications

• Material form: pre-cut thermal pad
• Color: grey (indicative of thermal conductivity properties)
• Weight of package: 25 g
• Dimensions: 30 mm x 30 mm
• Thickness: 3 mm

How to use

Before installation, clean both surfaces thoroughly to remove dust, grease and old thermal compounds using isopropyl alcohol or a recommended electronic cleaner. Remove protective films if present and place the pad onto the cooler or component, aligning it to cover the intended contact area. Apply even pressure when assembling the parts to ensure the pad conforms and fills gaps; avoid excessive compression beyond the pad’s specified thickness. If trimming is necessary, cut the pad with a sharp blade to the required size prior to placement.

Usage recommendations

Use this thermal pad in environments within typical electronic operating temperature ranges and avoid prolonged exposure to temperatures or chemicals beyond manufacturer guidelines. Replace the pad if it becomes compressed, contaminated, or damaged to maintain optimal thermal performance. For best results, verify mechanical fit and contact pressure during initial assembly and after any maintenance.
