Now with degradation metrics so that you can see when to replace your fan before it fails.

[The Wright Fan @WrightOne_Inc]

The only fan you will ever need.

[Justin McAfee @jusmcafee]

17 Wright Fan miners vs. 278 stock miners at the same facility for 26 days.

Same inlet air, same workload, same curtailment exposure.

WF avg chip temp: 72.5°C · 3.21 downtime events/miner/mo
Stock avg chip temp: 75.4°C · 9.64 events/miner/mo

@SnorkelHotTubs @btc_conference I’m interested

[Justin McAfee @jusmcafee]

This is one of my favorite artists. Incredibly creative and I LOVE this practice video. I want to see more of this, and would love to do this to show others my workflow.

We are currently collecting over 1 billion points of data everyday.

[The Wright Fan @WrightOne_Inc]

And now we are quantifying cooling degradation across ~5,000 fan systems. Stock and Wright Fan you can see your fans cooling performance for yourself today!

[Justin McAfee @jusmcafee]

@Braiins Continuous Tuner (opt-in beta)
• Runs tuning continuously to adapt to changing conditions
• Automatically adjusts to temperature and environment
• Available in Configuration → Advanced

Love this! Does it measure thermal headroom on cooling systems to maximize hashrate?

[Justin McAfee @jusmcafee]

Love seeing this!

[Snorkel Hot Tubs @SnorkelHotTubs]

UPDATE!! We are headed to Vegas to bring a Hashtub to the floor! The offer still stands - buy the floor tub (6’ diameter) and get 20% off an entire hot tub package. As usual it’s your choice of heat - wood fired, electric, gas or be a HEATPUNK and get the https://t.co/c2BhkGFQ1B with bitcoin mining heat from @HashrateHouse
If you buy it before the conference you’ll also receive 2 pro passes to the Las Vegas Conference. April 27-29.

See y’all in Vegas!

Thanks @HashHeatpunks for installing the first one at @SpaceDenver

Thanks @TheBitcoinConf for making this happen.

@CincoDoggos @simpleminingio What’s your uptime average with your host?

[Justin McAfee @jusmcafee]

@ranthiscal1time @simpleminingio The Wright Fan?

[Justin McAfee @jusmcafee]

@simpleminingio Replacing the fans to get better degradation metrics on cooling

[Justin McAfee @jusmcafee]

@simpleminingio The last 3 ASIC generations improved ~10–15%.

You can get that today without buying a new miner.

New miner: $3,000
Cooling upgrade: $80–$150
If cooling delays upgrades by 6–12 months:

You didn’t extend lifespan —
you deferred capex.

Most operators are upgrading too early.

[Justin McAfee @jusmcafee]

@compass_mining So, do you guys de-rack miners for fan replacements? That's quite the wall. Asking for a friend.

[Justin McAfee @jusmcafee]

@tylerkstevens So funny you should say this, I already am running miners with solar panels and Tesla power walls to test the S19s for Wright Fan development.

[Justin McAfee @jusmcafee]

Machines don’t fail — they get unstable first.

We measure RPM instability in real time
(stock fans included).

Variability ↑ → temps ↑ → hashrate ↓

That’s the signal before failure.

Run it. Prove us wrong.

[The Wright Fan @WrightOne_Inc]

[Justin McAfee @jusmcafee]

Most track failures. Few track decay.

We measure on stock fans too:

• Runtime between failures
• Downtime events + duration
• Recovery cycles
• Degradation trends

Hashrate is lost before failure.
Test it. Prove us wrong.

[Justin McAfee @jusmcafee]

Plugged into Luxor’s stack.

We measure degradation on stock fans — not just Wright Fan.

Most hashrate is lost before failure.

Test it. Prove us wrong.

[The Wright Fan @WrightOne_Inc]

@guzmanpintos @luxor Huge release — Luxor Commander is pushing the stack forward.

We’re already using Luxor APIs to go one layer deeper:

THERMAL STABILITY.

Most hashrate loss happens before failure ~5% to 15%.

That’s where we’re focused.

[Daniel Batten @DSBatten]

One of the best TL;DRs I've seen on why Bitcoin mining can do what AI datacenters can't, and it's even got @thetrocro's famous dungbeatle quote in there.

[The Wright Fan @WrightOne_Inc]

The only fan you will ever need.

[Justin McAfee @jusmcafee]

@luxor Excellent. Sounds like you need the Wright fan to match your capability.
