Frequently Asked Questions

Can I convert my own S9 into a Space Heater?

Yes. D-Central also provides consultation and parts for DIY conversions. However, the professionally tuned edition ensures optimal noise levels and thermal management.

Is the mining performance the same?

The Space Heater Edition may be slightly underclocked for noise reduction, which marginally reduces hashrate. The trade-off is a dramatically quieter machine suitable for living spaces.
