When it comes to overclocking, immersion cooling makes it possible to boost an S19 from default 110Th/s at 3250W per miner up to 155Th/s-165Th/s at 6500W.
The idea for immersion cooling is:
- the fluid has great heat absorption capacity which is many times better than heat
- transfer capacity of air;
- much longer lifetime for miners and lower TCO;
- much higher hashing rate thanks to overclocking (which is not possible with air cooling) and faster ROI;
- no dust, no noise, no overheating, no chips or dashboards burning;
- fewer repairs and maintenance actions;
- possibility of selling miners after 2-3 years in the fluid as new.
In addition, it seems that cooling is more important than ever for the Antminer X19 generation. Lower temperatures are directly correlated to lower power consumption and better efficiency to a greater extent than with previous generations of Antminers. Optimizing your infrastructure and miner configurations to maintain as low of temperatures as possible can make a big difference in the performance of your rigs.
