Hashboard Thermal Paste (Gray)

Description

Hashboard Thermal Paste

The Hashboard Thermal Paste (Gray) is a high-performance thermal compound formulated specifically for ASIC miner hashboard maintenance. It fills the microscopic gap between the ASIC chip and the heatsink, ensuring efficient heat transfer that keeps your chips running at stable temperatures and extends their operational life. This is the same thermal paste used in D-Central’s professional ASIC repair shop in Laval, Quebec.

Every ASIC chip on a hashboard generates significant heat under load. The thermal interface between the chip and heatsink is critical — dried-out or insufficient thermal paste creates an insulating air gap that causes chips to throttle, produce errors, or fail entirely. If your miner is running hotter than expected, producing inconsistent hashrates, or throwing temperature warnings after 6+ months of operation, re-applying thermal paste is one of the most effective maintenance steps you can take.

This is a bulk-sized container designed for technicians and serious home miners who maintain multiple machines. A single hashboard typically has 30 to 80+ ASIC chips depending on the model, and each chip needs a fresh application. One container covers multiple hashboards, making it far more cost-effective than buying small syringes.

Key Features

• Optimized for ASIC hashboards — formulated for the specific thermal demands of ASIC chips running under continuous 24/7 load. Standard PC thermal paste is not designed for the heat density and operating environment of mining hardware.
• Long-term stability — resists drying and separation under sustained high temperatures. Will not pump out or degrade prematurely, maintaining consistent thermal performance for months.
• Bulk quantity — enough to re-paste multiple hashboards. Each Antminer S19 hashboard has 76 ASIC chips; each Whatsminer M30 board has 56. A single container handles several complete board re-pastes.
• Easy application — gray silicone-based formula spreads evenly across chip surfaces. Apply with a spatula or plastic scraper for uniform coverage.
• Universal compatibility — works with all major ASIC miner brands and models. No compatibility concerns between paste chemistry and heatsink materials.

When to Re-Apply Thermal Paste

• After 6–12 months of continuous operation — thermal paste degrades over time under sustained heat. Industry practice is to re-paste hashboards at least annually.
• After chip replacement or rework — any time a heatsink is removed from a hashboard, the thermal paste must be cleaned and re-applied.
• When temperatures climb above baseline — if your chip temperatures are 5–10°C higher than when the miner was new, dried thermal paste is the most likely cause.
• When you see inconsistent hashrate — thermal throttling from poor heat transfer causes hashrate fluctuations and increased error rates.

Frequently Asked Questions

How many hashboards can I re-paste with one container?

The exact coverage depends on the chip count per board and application thickness, but one container is sufficient for multiple complete hashboard re-pastes. An Antminer S19 has 3 hashboards with 76 chips each (228 chips total). A Whatsminer M30 has 3 boards with 56 chips each (168 chips total). You will get several full-machine re-pastes from a single container.

Can I use regular PC thermal paste on ASIC hashboards?

While standard thermal paste will technically work, it is not ideal. PC thermal paste is designed for a single CPU/GPU die with moderate heat output. ASIC hashboards have dozens of chips packed tightly together, running 24/7 at high temperatures. Hashboard-specific thermal paste is formulated for this environment — better resistance to drying, pump-out, and thermal cycling over extended periods.

How do I apply thermal paste to a hashboard?

First, remove the heatsink from the hashboard. Clean all old thermal paste from both the chip surfaces and the heatsink using isopropyl alcohol (90%+) and lint-free wipes. Apply a thin, even layer of fresh paste to each chip surface using a small spatula or plastic scraper. Reinstall the heatsink with even pressure. Do not over-apply — excess paste can squeeze onto surrounding components.

Is this electrically conductive?

No. This is a standard gray silicone-based thermal compound that is electrically non-conductive. Accidental contact with nearby components will not cause shorts. This makes it safer for hashboard work compared to liquid metal thermal compounds.
