I explain the operating principle behind my chiller and basically, why my design works whereas others typically fail using these. I ran this 100 watt laser for about 5 hours at full power with no issues using this chiller method, working great so far. Everybody said I'd just trash the tube but I figured this was better than just a reservior. I keep an eye on the temps so whatever. 🤷♂️
