MICROBT · WHATSMINER M66S
Whatsminer M66S | 302 TH/s Immersion Bitcoin Miner
Immersion Mining · 302 TH/s · 18.5 J/TH · ~5587 W
Immersion Cooled SHA-256 · BTC Ultra-Low Noise PSU Included
The MicroBT Whatsminer M66S is a proven immersion-cooled SHA-256 Bitcoin (BTC) miner built for demanding, high-density mining operations. It delivers a solid 302 TH/s hashrate at about 18.5 J/TH, drawing roughly 5587 W. Designed to run submerged in dielectric coolant, the M66S delivers excellent thermal management, near-silent operation, and long hardware life by eliminating dust, hotspots, and mechanical fan wear. A dependable, cost-effective way to add Bitcoin hashpower to any immersion-tank farm. PSU included.
|
Immersion Cooling Submerged in dielectric fluid for superb heat transfer, no dust and no hotspots. |
302 TH/s Output Strong single-unit hashpower for dense immersion-tank layouts and scalable farms. |
|
Ultra-Low Noise Fan-free submerged operation runs near-silent, ideal for high-density deployment. |
Long-Life Reliability No fans and no dust mean a lower failure rate and longer hardware lifespan. |
Technical Specifications
What's Included in the Package
Note: An immersion-cooling tank, dielectric coolant, circulation/heat-exchange system, and 380–480 V power infrastructure are required and are not included. Please confirm exact shipment contents with our sales team before ordering.
Worldwide Shipping & Deployment
Built for the 380–480 V industrial power and immersion-tank infrastructure used by mining farms across the USA, Canada, European Union, Middle East, Central Asia, Russia, Ethiopia, Paraguay and beyond. Immersion cooling makes the M66S especially strong in hot climates and dusty environments where air cooling struggles. Its near-silent, high-density design suits professional immersion facilities that prioritise uptime and hardware longevity. DDP shipping options available on request.
Frequently Asked Questions
Do I need an immersion tank to run it?
Yes. The M66S is built to run fully submerged in dielectric coolant, so you need a compatible immersion tank, fluid, and a circulation/heat-exchange system. It cannot run air-cooled.
Why choose immersion cooling?
Submerging the miner gives superb heat transfer, near-silent operation, no dust build-up, and no fan wear – which means more stable performance and longer hardware life, especially in hot or dusty locations.
How does the M66S compare to the M66S+?
The M66S is the more accessible model at ~302 TH/s and 18.5 J/TH, while the M66S+ pushes higher hashrate (up to 356 TH/s) at better efficiency (~17 J/TH). The M66S is a strong value pick for immersion farms.
Which coins can it mine?
It runs the SHA-256 algorithm, so it mines Bitcoin (BTC) and other SHA-256 coins such as Bitcoin Cash (BCH) and Fractal Bitcoin. It supports both pool and solo mining.
What warranty and shipping do you offer?
New units come with up to a 1-year warranty. We ship worldwide, with DDP options available on request – contact our sales team for rates and lead times.
