Cooling Solutions for Mining Farms: Air vs Immersion

Mining rigs pull heavy power and throw off heat that quickly drives up failure rates if you ignore it. Air cooling still dominates most farms because it costs less upfront, while immersion cooling cuts energy waste and noise once you scale past a few dozen units.

Air Cooling Systems in Mining Farms

You set up rows of ASIC miners with intake fans pulling outside air across the boards and exhaust fans pushing hot air out through roof vents or ducts. In a 500-rig warehouse in Texas, operators run 20 large axial fans plus evaporative coolers during summer peaks to keep inlet air under 30 C.

• Initial install stays simple: mount fans, add basic filters, and wire thermostats.
• Power draw for fans and AC can reach 15 percent of total load when ambient hits 35 C.
• Dust buildup forces filter changes every two weeks in dry climates, otherwise hash rates drop from thermal throttling.

Immersion Cooling Approaches

Miners sit fully submerged in dielectric fluid inside sealed tanks. A single 200 kW tank holds 40 S19 units and routes fluid through an external dry cooler. One Midwest farm switched 120 rigs last year and dropped their cooling power share from 18 percent to 4 percent.

Single-phase setups use pumps and plate heat exchangers. Two-phase versions let fluid boil at low temperature and condense on a lid coil, which removes even more heat per liter of fluid moved.

Side-by-Side Performance Check

Air works fine when electricity stays cheap and space is plentiful. Immersion pays off faster once power rates exceed $0.06 per kWh or when you need to pack more rigs into an existing building without new HVAC permits.
