I am unable to bring things into Ecuador inexpensively. But I did find a fan in my own personal stock of computer stuff. It was a perfect fit for a replacement fan in the Color Classic. I will enclose a data sheet. It is a Panaflo model # FBAO08A 12U. 12 is for 12V and the "U" is for "Ultra High Speed".
Just using my hand over the outside of Color Classic, I can tell I have more air flow. How much more, I do not know. But it is better.
This fan has a slight annoying sound to it. The volume is low, but the original Color Classic fan was whisper quiet. I hope I can forget the sound...
I tried to contact the web master of the new PowerCC.org. But the "send email" part of the web site is not working. I think this person could archive the data sheet you posted and perhaps this one, so folks that want to upgrade the fan in a color classic would know what type kind and size to look for.
Thanks for all your help.
