DOWSIL TC-3080 8W/mK Blue Thermal Gel (1kg) for ASIC Miner Hashboards

DOWSIL TC-3080 Blue Thermal Gel 8.0W/mK – 1kg Pail for ASIC Miner Hashboards

The DOWSIL TC-3080 is a factory-grade silicone thermal gel with a measured thermal conductivity of 8.0W/mK, supplied in a 1kg pail for hashboard repair shops and mining farms. It sits on the high end of the silicone-based gel range and is well-matched to dense ASIC hashboards like Antminer S21 / S21 Pro / S21 XP and Whatsminer M50 / M60 series where chip TDP and chip count put real demands on the thermal interface material.

Why TC-3080 vs Cheaper Greases

Traditional 5-6W/mK pastes work, but as ASIC chip TDPs climb past 25-30W per chip, the thermal interface becomes a bottleneck. TC-3080's 8W/mK conductivity reduces the temperature delta between the chip die and the heatsink base, which on a typical S21 hashboard translates to 3-6°C lower chip junction temperatures at full hash. The silicone base also has very low pump-out under thermal cycling, so the joint stays full over the life of the miner.

Application

Clean each chip top and the matching heatsink contact area with isopropanol. Use a stencil sized for the hashboard (Antminer S21, Whatsminer M50, etc.) to dispense an even bead onto each chip. Lower the heatsink straight down — do not slide — and clamp at the recommended torque. A 1kg pail is enough for roughly 40-60 hashboard rebuilds depending on chip count and stencil thickness.
