I have built 8 amplifiers with water cooling. I can testify that it is much more effective than air cooling, and with less noise. There is a much simpler way to do it than shown in the video (although it is a great job!). I braze copper tubing onto the bottom of the heat-spreader. Pumps and radiators are all available on eBay and if you do your tubing right, you will never get any coolant leak. I use distilled water with 20% glycol.

And what is the KPA1500 fan noise level at 90°C?

LOUD!
