That time my GPU rig cooked my lettuce before I could harvest it

I set up a small grow box next to my mining rig back in 2021, figured the heat would be perfect for some romaine. Left for a weekend trip to Denver and came back to leaves that looked like they'd been through a blowtorch. The exhaust fan had died on Friday night, so the temps spiked to around 95F and just roasted everything for two days straight. I tore it all out, added a cheap thermostat switch from Amazon for $15, and now I point the airflow at my herbs instead. It's a constant lesson in watching your gear, not just your hash rate. Anyone else lost a whole crop to a single fan failure?

Heard about a guy on a hydroponics forum who lost an entire basil harvest the same way, his inline fan seized up overnight and the tent hit 100 degrees by morning. That story actually got me to buy a backup fan and a wifi temp alarm before I ever even built my own setup. It's wild how one little part failing can wipe out weeks of careful growing, and with mining rigs the stakes are even higher because you're dealing with constant heat output. I started logging my temps every hour on a spreadsheet after that happened to me, just so I could spot trends before they became disasters. The $15 thermostat switch was a smart move, but honestly the real lesson is redundancy, always have a second way to move air out of the room.
