Rig Maintenance 101: Cleaning, Repasting, and Extending Hardware Life

Most rigs lose performance from heat long before parts actually fail. A consistent cleaning and repasting routine keeps temperatures down and delays the need for upgrades.

Removing Dust Before It Builds Up

Dust on fans and heatsinks blocks airflow fast. In a typical home setup with carpet and pets, you will see GPU temps climb 8 to 12 degrees after four to six months if you do nothing.

Power off and unplug the system.
Use compressed air on fans while holding the blades still so they do not spin and damage bearings.
Vacuum the case filters and wipe the exterior vents with a microfiber cloth.
Check the power supply intake every year; that fan often gets neglected and still pulls in lint.

Repasting at the Right Time

Factory thermal paste dries out after two to three years under load. You do not need to repaste every time you clean, but watch for rising idle or load temps on the same hardware.

Remove the cooler, clean both surfaces with isopropyl alcohol and a lint-free cloth, then apply a pea-sized dot of high-quality paste in the center. Reinstall the cooler with even pressure. Test with a stress tool for twenty minutes and log the new peak temperature.

Tracking Results After Each Session

Keep a simple log of temperatures before and after maintenance. A basic table works well.

Component	Before Clean	After Clean + Repaste
GPU load	82 C	71 C
CPU load	78 C	69 C
Case exhaust	48 C	39 C

If temps stay high after service, check fan curves or confirm the cooler made full contact.

Small Habits That Protect Hardware

Raise the case a few inches off the floor so it pulls less carpet dust. Replace intake filters every six months instead of waiting until they turn gray. Keep intake and exhaust paths clear of cables so air moves in a straight line. These steps alone often add two or three years before fans or thermal paste need attention again.

The True Cost of Electricity in Mining: Calculating Your Break-Even Point

Electricity often decides whether a mining setup turns a profit or drains cash each month. The break-even point shows exactly how many coins you need to mine before power costs wipe out revenue. Run the numbers on your actual rate and hardware before you plug anything in.

Pinpointing Your Real Electricity Load

Start with the equipment itself. An S19 draws about 3.25 kW at the wall once you factor in PSU losses and fans. Measure with a kill-a-watt meter on-site rather than trusting the spec sheet. Add the router, switches, and any exhaust fans that run 24 hours.

Your local rate matters more than the national average. Industrial users in Texas often pay 6 cents per kWh during off-peak, while parts of California hit 28 cents. Check your last bill for the all-in rate that includes demand charges and taxes. Multiply that rate by total kW and hours to get monthly power cost.

Component	Power Draw	Monthly kWh (730 hrs)
Single S19 miner	3.25 kW	2,373
Network gear + fans	0.4 kW	292
Total per rig	3.65 kW	2,665

Calculating Break-Even Hashrate

Take your monthly power cost and divide by the coin price to find how many coins you must mine just to cover electricity. Then divide that coin amount by the expected daily output per TH/s. The result tells you the minimum hashrate your rig needs to stay above water.

Try this example with Bitcoin at $62,000 and a 6-cent power rate. Your single S19 costs roughly $160 per month to run. At current difficulty that machine produces about 0.00028 BTC monthly, worth $17.36. You lose money until either the coin price rises or you add more machines to spread fixed costs.

Record your measured kW draw and multiply by 730 hours.
Multiply total kWh by your actual cent-per-kWh rate.
Divide monthly power cost by current coin price to get break-even coins.
Divide that coin number by output per TH/s from a mining calculator.
Compare the result to your actual deployed hashrate.

If your rig sits below that threshold, either negotiate a lower rate, move to a cheaper power region, or shut down until conditions improve. Many operators learned this the hard way in 2022 when power bills stayed fixed while revenue dropped 70 percent.
