This was the second one that I've done. I bought 4 fans and 10 converters, and I plan to do this for each one of my Cocos, Ataris, C64s, etc, as I pull them out for the next usage!
@@acs8-bitzone651 First fan successfully installed! This went into a model 26-3134 CoCo 2. With its smaller motherboard, I had no trouble affixing the fan to the underside of the keyboard and aiming it at the big heatsink. There's also plenty of space next to the motherboard to mount the converter to the bottom of the case using double-sided tape. Thanks for the great idea!
@@paulshoemaker4761 Awesome to hear! This really will help our motherboards. On my 26-3127 (I believe that's right), the heatsink is a deep "U" shaped design. There is enough room to stick the fan to its left between heatsink and case, and then the air is pulled from the transformer and directly through the U shaped passage. It then spreads evenly throughout the upper vent areas to escape. It's really ideal. Glad you found this useful!
I agree, soldering can be therapeutic and being too lazy to get the wire strippers..... I know the feeling well. I love the way you work, great video and keep it up!
Why not ties a 120vac fan to the power switch of the CoCo2 so you A) do not need to worry about loading down the CoCo2's power supply. and B) it turns on off with computer with out using any additional hardware.
It is loading the transformer and rectifier diodes that make the 12V rail. It shouldn't be too much loading for the transformer. It is tapping upstream of the +5V power supply that was running hot. However, your idea works just as well and has the benefit you noted.
That will work too. One feature that I would miss though is the ability to turn down the voltage with the set screw for slowing the fan and allowing it to run a little quieter.
The other end of the little C3 capacitor, opposite end from the +12V. There are other caps that also connector the GND. The foil ground plane connects them together.
Great video glad to see posting again!
The CoCo is now CoolCool! 🙂
Doing this! Just ordered the parts.

Yeah, lol. You know, grabbing the wire strippers would have required me to stand up and reach into a container. Too much effort for two little wires.
Glad to see you again!
😎
it should improve as the case is on. You might even be able to make the fan even more quiet.
I agree!

On second thought use a power supply like you did, but one that runs off the AC to power it directly off the AC power switch.
It is loading the transformer and rectifier diodes that make the 12V rail. It shouldn't be too much loading for the transformer. It is tapping upstream of the +5V power supply that was running hot. However, your idea works just as well and has the benefit you noted.
If I use a 12v fan then I wouldn't need that regulator unit, right? Just find 12v and wire the fan directly?
That will work too. One feature that I would miss though is the ability to turn down the voltage with the set screw for slowing the fan and allowing it to run a little quieter.
@@acs8-bitzone651 I have some spare potentiometers - wire one of them in series? And what's the easiest spot to grab 12v? I have a TDP and a Coco3.
Where did you connect the black wire to the motherboard?

Coco nut 🤣🤣🤣🤣🤣
