💻🔥 Boiling Water with CPU While Mining Monero! i5 Experiment #3
Can an old Intel Core i5 CPU heat water while mining cryptocurrency? In this third and final experiment of my CPU water-heating series, I pushed an old Intel i5 processor to its limits while running Monero (XMR) mining.
Instead of using a traditional heater, I wanted to see how much heat could be transferred from a CPU running at full load into a container of water.
And the results? After approximately 1 hour and 30 minutes, the water temperature reached around 72°C! 🔥
🧪 Experiment Details
For this unusual experiment, I used an old computer and continuous CPU mining to generate heat.
Hardware and setup: - CPU: Intel Core i5 (3rd generation) - Workload: Monero (XMR) CPU mining - Mining load: 100% CPU utilization - Heating time: Approximately 1 hour and 30 minutes - Water temperature: Approximately 72°C - Insulation: Paper cups
The idea was simple: use the heat generated by cryptocurrency mining and transfer as much of it as possible to the water.
🌡️ The Results
After running the CPU miner continuously, the water temperature climbed to approximately 72°C.
That's quite impressive for an experiment using an old desktop processor!
Of course, this isn't an efficient way to heat water. A dedicated electric heater would be much more practical, but the interesting part is seeing how much waste heat a CPU can produce when mining Monero.
💰 Mining Monero While Heating Water
Monero uses the RandomX algorithm, which is designed to work efficiently on general-purpose CPUs.
During this experiment, the processor was doing two things from our perspective:
- Performing RandomX calculations for Monero mining.
- Producing heat that could be transferred to the surrounding setup.
It is a fun demonstration of how computer hardware converts electrical energy into heat.
🔥 Final Experiment of the Series
This was the third and final video in my CPU water-boiling experiment series.
It was interesting to see how far an old Intel i5 could go when pushed to full load. While it certainly isn't a replacement for a kettle, it makes for a fun hardware experiment!
What should I try next? Maybe another old CPU, a different mining algorithm, or an even crazier DIY heating project?
