Thermal pad Alphacool 12463

The Alphacool 12463 thermal pad is a pre-cut grey heat interface material measuring 120 mm x 120 mm x 1.5 mm, supplied as a pack of two. It is designed to provide consistent thermal conductivity between electronic components and heatsinks or cooling plates, supporting effective heat transfer in computer and electronic cooling applications. The soft, conformable material fills micro-gaps and improves contact where mounting pressure or surface flatness is limited.

Advantages

The thermal pad offers uniform thickness and consistent thermal performance across its surface, simplifying installation compared with liquid thermal pastes. Its grey formulation combines flexibility and thermal conductivity while remaining non-adhesive for easy repositioning. Supplied in a pack of two, the pads allow replacement or use on multiple components without cutting multiple pieces from a single sheet.

Suitable for

• Thermal bridging between chips (e.g., VRMs, memory modules) and heatsinks
• Filling gaps in water-cooling blocks and radiators where precise thickness is required
• Cooling small form-factor electronics and enclosures

Key specifications

• Dimensions: 120 mm × 120 mm
• Thickness: 1.5 mm
• Colour: Grey
• Pack quantity: 2 pads
• Weight: 0.05 kg (pack)

How to use

Clean both mating surfaces to remove dust, grease and old thermal materials. Cut the pad to the required shape if necessary and remove protective liners before placement. Position the pad on the component so it fully covers the contact area, then mount the heatsink or cooling plate with even pressure to ensure good contact. If thicker or thinner contact is needed, use multiple pads or trim to achieve the desired gap fill.

Usage recommendations

Store unused pads flat and in a dry environment to preserve physical properties. Avoid excessive shear or stretching during installation. Replace the pad if it becomes deformed or contaminated to maintain optimal thermal transfer.
