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

Factor	Air Cooling	Immersion Cooling
Upfront cost per rig	$180-250	$650-900
Energy overhead	10-20 percent	3-6 percent
Maintenance interval	Weekly filter checks	Fluid test every 6 months
Noise at full load	75-85 dB	Under 50 dB
Max density	Low, needs wide aisles	High, tanks stack closer

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.

How to Choose the Most Profitable Cryptocurrency to Mine

How to Choose the Most Profitable Cryptocurrency to Mine

Pick the coin that delivers the highest net return after your hardware and power costs. Start by listing your exact equipment and local electricity rate, then compare coins that your rig can actually hash.

Match Coins to Your Hardware

GPUs work best on memory-heavy algorithms like Ethash or KawPow. ASICs dominate SHA-256 coins. If you run two RTX 3070 cards, focus on coins such as Ravencoin or Ergo rather than Bitcoin. Running the wrong algorithm on your cards cuts output by half or more.

Calculate Power Costs First

Electricity usually eats 60 to 80 percent of mining revenue. Measure the wattage your rig pulls at the wall under load. At 0.10 dollars per kWh a 1200-watt rig costs 2.88 dollars per day. At 0.25 dollars per kWh the same rig costs 7.20 dollars. Subtract that number from projected daily coin value before you choose a target.

Check Network Difficulty and Block Rewards

Higher difficulty spreads the same reward across more miners, so daily payout drops.
Block rewards halve on schedule, which can turn yesterday’s profit into today’s loss.
Look at the last 30 days of difficulty charts on a site like WhatToMine or the coin’s own explorer.

Compare Coins Side by Side

Coin	Algorithm	Daily Revenue (3070 rig)	Power Cost at 0.12/kWh	Net Profit
Ravencoin	KawPow	3.40	2.10	1.30
Ergo	Autolykos2	3.10	2.05	1.05
Kaspa	kHeavyHash	4.80	2.20	2.60

Update the numbers every few days because prices and difficulty move fast.

Run a Seven-Day Test Before Scaling

Mine the top two coins from your table for 48 hours each.
Record actual coins received and wallet payouts.
Switch to the third coin for another 48 hours.
Keep the rig on the winner and set a calendar reminder to recheck in one week.

Small differences in pool fees or stale shares often decide which coin stays ahead once you see real results.

Understanding Mining Pool Fees and Payout Structures

Understanding Mining Pool Fees and Payout Structures

Mining pools take a cut of your rewards through fees, and the way they distribute those rewards depends on their payout structure. Both directly affect how much you actually keep. Most pools charge between 1% and 3%, though some go higher or use zero-fee models that shift costs elsewhere.

How Fees Reduce Your Rewards

Fees get deducted before you receive anything. On a pool with a 2% fee, every 0.05 BTC you earn drops to 0.049 BTC after the cut. That difference compounds when you mine daily or when network difficulty rises.

Check the exact fee type before you join. Some pools apply the percentage only to the block reward itself, while others also deduct it from transaction fees. A pool that looks cheap on the reward can still take more from you when blocks carry high fees.

Fixed percentage: straightforward but still reduces daily output.
Tiered fees: lower rates once you hit a hashrate threshold.
Zero-fee pools: often make money by holding your coins longer before payout.

Common Payout Structures

Pools use different methods to calculate shares and send payments. The structure decides how soon you get paid and how much variance you face.

Structure	When You Get Paid	Best For
PPS	After each valid share	Steady small miners who want predictable daily income
PPLNS	After a block, based on recent shares	Larger operations that can handle short dry spells
PROP	After block matures	Miners comfortable waiting for confirmations

Take a 10 TH/s rig on a PPLNS pool. If the pool finds a block after you contributed 4% of shares in the window, you receive roughly 4% of the reward minus the fee. Switch the same rig to PPS and you receive payment per share submitted, regardless of whether the pool finds a block that round.

Matching a Pool to Your Setup

Run the numbers on your expected daily output first. A 1.5% fee on a pool that pays every four hours often beats a 0.8% fee pool that holds funds for a full day. Test small withdrawals to confirm the actual arrival time and any hidden network fees.

If your rig goes offline for several hours, PPLNS pools penalize you more than PPS ones because only your active shares count. Keep that in mind when you plan maintenance or power costs.

Best Power Supplies for Crypto Mining Rigs in 2025

Best Power Supplies for Crypto Mining Rigs in 2025

Most miners running multiple GPUs hit efficiency walls and stability issues when their power supply cannot sustain continuous loads above 1200W. The units that hold up best this year deliver 80 Plus Platinum or Titanium ratings, come with 1600W to 2000W continuous output, and use fully modular cabling so you only run the lines you need.

Practical choices for 6- to 12-GPU rigs

Start by matching PSU capacity to your actual draw. A rig with six RTX 3080 cards pulls roughly 1400W at the wall under load. Add headroom for spikes and future cards, and you land on 1800W units. Lower wattage supplies force you to run two PSUs in parallel, which adds failure points and extra heat.

Model	Rating	Continuous Watts	Best for	Notes
Seasonic Prime TX-1600	Titanium	1600W	8-GPU Ethereum or Kaspa rigs	Single 12V rail, 10-year warranty
Corsair AX1600i	Titanium	1600W	Variable loads	Digital monitoring via software
EVGA SuperNOVA 2000 T2	Titanium	2000W	10-plus GPU farms	Requires 20A circuit per unit

Check that the unit has at least four 8-pin CPU connectors repurposed for PCIe power when needed.
Verify the fan curve stays quiet below 60% load. Mining rooms often run 24/7, so noise compounds fast.
Measure input voltage at the outlet. Titanium units lose less than 4% efficiency at 10% load, which matters when rigs idle overnight.

Buy from vendors that stock replacement cables separately. A single missing 6+2 pin lead can force you to shut down an entire rig until a new cable arrives. Seasonic and Corsair both sell individual cables by part number, which keeps downtime short when something wears out.
