Thermal Paste Gel 5.5W G18 YS346 30CC Silicone-Based Solution for Crypto Miner

Thermal Paste Gel 5.5W G18 YS346 – Professional Heat Dissipation for ASIC Miners & GPU Rigs

The G18 YS346 is a professional-grade, silicone-based thermal interface material delivering 5.5 W/m·K conductivity in a convenient 30 CC syringe. Engineered for ASIC miners, GPU rigs and high-power semiconductor assemblies, this non-curing thixotropic gel fills microscopic surface imperfections between heatsinks and heat sources to minimise thermal resistance. Its formulation maintains stable performance across a wide -40 °C to +180 °C operating window, making it suitable for both air-cooled and water-cooled mining installations.

Why Thermal Paste Quality Matters in Mining

ASIC chips in modern miners such as the Antminer S19 or Whatsminer M30 series routinely dissipate 20–40 W per chip, and a single hashboard may carry dozens of them. Poor thermal interface material degrades over time — hardening, cracking or migrating away from the die surface — leading to localised hot spots that throttle hash rate or trigger protective shutdowns. The G18's non-curing formula resists pump-out and dry-out, maintaining a thin, uniform bond line even after thousands of hours of continuous operation.

Application Guide

Clean the heatsink and die surfaces thoroughly with isopropyl alcohol (IPA) and a lint-free cloth before application. For flat ASIC dies, dispense a thin X-pattern across the chip surface and let the heatsink mounting pressure spread the material evenly — avoid over-applying, as excess paste can spill onto nearby SMD components. The 30 CC syringe format works with standard pneumatic dispensers for high-volume rework lines, or can be applied by hand with the included nozzle for individual board repairs. One syringe typically covers 15–25 ASIC chips depending on die size.

For hashboards that use thermal paste stencils (such as the S19 or L7 series), the G18's thixotropic consistency ensures it sits within the stencil openings without bleeding, providing uniform coverage across every chip on the board in a single pass.
