G19 YS383 8W/mK Blue Thermal Gel | 30CC / 110g Ceramic-Silicone Gap Filler for Antminer S21 BM1368 ASIC Chip Cooling and Hashboard Rework
The G19-YS383 8W/mK Blue Thermal Gel in a convenient 110g / 30CC dispenser is engineered for high-performance ASIC mining cooling — delivering superior heat transfer between ASIC chips and heat sinks on Antminer S21 and BM1368 / BM1368AA / BM1368PB generation hashboards. Fills the micro-gaps between chip die and cold plate, lowering thermal resistance to keep chip junction temperatures within their safe envelope under sustained mining load.
Built on a ceramic-filled silicone resin formulation that pairs 8 W/mK thermal conductivity with strong dielectric performance (≥2.5 KV/mm) and a wide -60°C to 200°C operating window. The UL-94 V0 flame retardancy rating meets strict mining-deployment safety standards. The 30CC syringe format fits standard manual push glue guns for precise, uniform coverage during single-miner maintenance or full-farm rework.
When to Apply the G19 Thermal Gel
- Antminer S21 hashboard reassembly — fresh paste between BM1368 chips and the cold plate after chip-level rework.
- Refurbishment of used S21 boards — old paste dried or pumped out, restore thermal interface to original spec.
- Whatsminer M50 / M60 series rework — same 8 W/mK envelope serves modern Whatsminer chip generations.
- Server / GPU cluster cooling — application extends beyond crypto to data center and high-performance compute heat sinks.
- Mining farm preventive maintenance — periodic re-paste reduces creeping thermal drift across the fleet.

FAQ — G19 Blue Thermal Gel
Q: Why 8 W/mK instead of higher-conductivity pastes?
A: 8 W/mK is the sweet spot for ASIC mining duty — high enough thermal conductivity to handle BM1368 / M50-class chip dissipation, while keeping the formulation pumpable through a 30CC syringe (higher-conductivity pastes tend toward higher viscosity and harder application). For S21-class workloads it's the validated balance.
Q: How much paste do I need per S21 hashboard?
A: Roughly 5-8g per hashboard depending on chip count and reapplication coverage. A 110g / 30CC syringe covers ~15-22 S21 hashboards, depending on application technique.
Q: Do I need a dedicated dispenser gun?
A: The 30CC format fits any standard manual push glue gun. For precise control across many boards, pair with the matching 30CC silicone grease dispenser gun — uniform coverage matters more than absolute paste volume.
Q: Bulk pricing for mining farms?
A: Yes — email contact@lys-sz.com with your monthly paste consumption for tier pricing on multi-syringe orders.
