I have one CoCo 3 that I installed a Pentium 1 fan in the top cover and ran
its power line to the hard drive power supply. I had the Dragonfly fan in a
CoCo 1 but that never seemed to help, and the buzz was annoying. I saw a
multi-pack on eBay recently that had a fan mounted to the right of the
In all truth, the Pentium 1 class CPU heatsink fan in the vents of the CoCo
3 is about all the fan any CoCo 3 can use. Aside from the RAM we just are
not dealing with the speeds and power consumption that make for a lot of
heat. Also, I'm given to understand that there is little reserve in the
CoCo's power supply to run a fan with.
