Laser Cooling

Now that my laser cutter is 3x larger than the old one, that means it's cutting 3x longer and I'm also doing more complicated and intricate designs the laser definitely heats up to a point where I worry about how hot it is. Air based coolers range in price but the first actual chiller costs £400. By using water cooling parts from a PC I was able to knock together an air based cooler for £30. I'm still in the testing phase to see what difference it makes but it's a small investment compared to the £400 required for a proper chiller.
