Whatsminer M50 Thermal Grease Stencil Kit – Hashboard Tool

Whatsminer M50 Thermal Grease Stencil Kit | Hash Board Cooling Tool for 105 / 111 Chip Variants

The Whatsminer M50 thermal grease stencil kit is a precision paste-application tool for the MicroBT Whatsminer M50 hashboard — the air-cooled SHA-256 miner released July 2022 with a hashrate of 110-122 TH/s at 3306W (29 J/TH efficiency). The M50 hashboard ships in two chip-count variants — 105 chips or 111 chips per board — so the stencil kit is offered in matching versions for each layout, with front-side, back-side, or front+back configurations available.

Even thermal paste application is the difference between rated hashrate and chronic throttling on an M50 board. Manual application produces uneven coverage that creates hot spots; the laser-cut stencil deposits a uniform layer in a single pass, eliminating bubble formation, ensuring full contact pressure across all chip dies, and reducing the application time by roughly 3× per board.

When to Use the M50 Thermal Grease Stencil

• M50 hashrate drop below 110 TH/s — degraded paste interface causing throttling; refresh with stencil application.
• Hashboard repair after chip replacement — apply fresh paste before reseating the heatsink.
• Mining-farm preventive maintenance — schedule paste renewal every 12-18 months for fleet hashrate stability.
• Air-cooled M50 returning from storage — original paste likely degraded, full refresh recommended before redeployment.
• Repair-bench production work — consistent application across multiple boards per shift.

Chip-Count Variants — Choose the Right Stencil

• 105 chips per hashboard — earlier M50 production run; check chip count on your board before ordering.
• 111 chips per hashboard — later M50 production run with higher density; different stencil pad layout.
• Front plate only — chip-side paste application.
• Back plate only — backside thermal interface to heatsink.
• Front + Back plates — complete kit for full hashboard refresh.

FAQ — Whatsminer M50 Thermal Grease Stencil

Q: How do I know if my M50 has 105 or 111 chips?
A: Count the chip positions on one hashboard — the chip array is visible after removing the heatsink. M50 boards built in 2022 production typically use 105 chips; later boards switched to 111 chips for higher hashrate. The chip-count silkscreen marker on the board edge sometimes confirms the variant.

Q: Should I order the full kit (front + back) or just the front plate?
A: For complete hashboard refurbishment, the front + back kit applies paste to both the chip-die side and the backside thermal interface. For chip-level repair after a single chip replacement, the front plate alone may be enough.

Q: Which thermal paste do you recommend?
A: A high-conductivity silicone-based grease (≥3 W/m·K — ideally 5+ W/m·K like G18). The M50 dissipates ~3.3kW continuously; lower-conductivity pastes can't move the heat fast enough.

Q: Will this stencil also fit the M50S or M60 hashboards?
A: No — M50S and M60 use different chip layouts and require their own dedicated stencil kits. See related products for those variants.

Q: Bulk pricing for repair shops?
A: Yes — email contact@lys-sz.com for volume pricing on M50 stencils + thermal paste in matched quantities.
