MicroBT WhatsMiner M70 (214Th/s)
Air cooling
Description
With air cooling, the WhatsMiner M70 (214Th) supports stable SHA-256 Bitcoin mining while delivering up to 214 TH/s.
Released in Dec 2025, it fits well in upgrade cycles where operators refresh to newer-generation efficiency.
Electrical planning is straightforward here: approximately 3140W under load, so density and cooling can be modeled in
advance.
This air-cooled layout suits traditional ventilation setups and rack rows where fan-driven airflow is already
engineered.
Product pages include hashrate, power, cooling type, and key specs so you can pick the right unit without guesswork.
If you’re selecting hardware by numbers, the spec sheet here is straightforward: hashrate, power, and cooling are
clearly defined for deployment planning.

Frequently Asked Questions
Customer Reviews
Definitely worth considering if you're in the market. Good balance of price, performance, and efficiency. No major drawbacks.
Solid performer. Running non-stop for months and the hashrate hasn't wavered. The consistency is what impresses me most.
Fine for what it is. Not the most efficient but it's reliable. If reliability matters more than efficiency to you, this is a solid choice.
Not bad! It's not the best but it gets the job done. Just be aware of power costs.
The silicone lottery blessed me with this unit. Running 15% above stock hashrate at stock voltage. Absolutely insane performance.
Very satisfied with the purchase. The miner arrived quickly, was easy to set up, and has been hashing away ever since. No nonsense.
