As promised, I have been documenting everything as I have gone through the process of converting my Power Mac G5 Quad from Liquid Cooling to Air Cooling. The results were richly satisfying: all four CPUs idling in the high 30 C area, all CPU fans running at their default low idle speeds.
I have written a document that I hope is a comprehensive A-Z guide to converting a G5 Quad from liquid to air cooling. This is a large’ish document (40 pages) but it is rich with images and photos, which pushes up both page count and file size.
This document is wild. I love it.
