Thermal Putty Alphacool Apex X1 30g – high‑conductivity thermal interface material

Alphacool Apex X1 Thermal Putty 30g is a high‑conductivity thermal interface material supplied in a pliable putty form. It is formulated to improve thermal contact between heat‑generating components and heatsinks by filling uneven surfaces, micro‑gaps and irregularities. The product is intended for use when reliable heat transfer is needed in PC cooling systems, custom liquid‑cooling assemblies and during component reassembly or maintenance.

Advantages

The putty consistency allows precise application to uneven surfaces and small cavities where traditional pastes or pads may leave air gaps. High thermal conductivity promotes efficient heat flow from CPUs, GPUs, voltage regulator modules and other electronic components to cooling solutions. The 30 g amount provides sufficient material for multiple applications or larger contact areas while remaining easy to handle and apply.

Suitable for

• Improving thermal contact between CPUs or GPUs and custom heatsinks
• Filling gaps in water‑cooling blocks and cold plates
• Thermal maintenance on VRMs, MOSFETs and power delivery components
• Reassembling components where surfaces are uneven or slightly warped
• PC builds and repairs that require durable thermal interface material

Key specifications

• Form: malleable putty for gap filling and surface conformity
• Net weight: 30 grams of thermal interface material
• Thermal performance: formulated for high thermal conductivity (material specifics per manufacturer)
• Application temperature range: suitable for typical electronic cooling environments
• Compatibility: designed for CPUs, GPUs, VRMs and other electronic heat sources

How to use

Clean both mating surfaces thoroughly to remove old thermal material, dust and oils. Take an appropriate amount of Alphacool Apex X1 putty and press it gently into the area to be filled, ensuring contact across the entire interface. Reassemble the heatsink or cooling block and apply mounting pressure so the putty spreads to fill micro‑gaps; avoid excessive force that could squeeze out too much material. After installation, verify proper seating and recheck temperatures under load to confirm improved thermal contact.

Usage recommendations

Store the putty in a cool, dry place and reseal the container after use to prevent contamination. Use gloves to avoid transferring oils from skin to the material. For critical or high‑power applications, monitor component temperatures after installation and reapply if thermal performance degrades over time.
