Thermal paste Arctic MX-7 heat sink compound, thermal interface material for CPUs and GPUs

Arctic MX-7 thermal paste in a 4 g syringe is a thermal interface material designed to improve heat transfer between processors and heatsinks. The compound fills microscopic gaps on CPU, GPU and other heat-generating surfaces to help reduce operating temperatures and maintain stable thermal contact. Supplied in a small syringe for precise application, the product is intended for desktop and laptop systems where controlled dispensing is required.

Advantages

The 4 g syringe format enables accurate, low-waste application and targeted reapplications during maintenance. The formulation promotes effective thermal conductivity across mating surfaces while remaining electrically non-conductive when applied correctly, reducing the risk of short circuits. The paste is easy to spread into a thin layer that ensures consistent thermal transfer.

Suitable for

• Desktop CPUs and CPU cooling assemblies
• Discrete GPUs and graphics cooling solutions
• Small form-factor PCs and compact cooling setups
• Repair, upgrade and routine maintenance of thermally sensitive components

Key specifications

• Brand: Arctic
• Net weight: 4 g
• Form: syringe for precise application
• Intended use: thermal compound for CPUs, GPUs and other heat-producing components

How to use

Power down the system and disconnect from mains before beginning. Remove the heatsink and clean both contact surfaces thoroughly with isopropyl alcohol and a lint-free cloth until no residue remains. Apply a small, pea-sized amount of Arctic MX-7 to the centre of the CPU or on the GPU die as appropriate, then remount the heatsink using even pressure so the compound spreads into a thin, even layer. Avoid excessive application; a thin film is sufficient for optimal thermal transfer. Reinstall the cooling assembly and verify secure mounting before powering the system on.

Usage recommendations

Store the syringe at room temperature away from direct sunlight and replace the cap after use to prevent drying. Inspect thermal paste condition during routine maintenance and reapply when thermal performance degrades or after removing the heatsink.
