You don't need an old computer fan to burn coal.
What, more specifically, are you talking about?

i know i dont need a computer fan to burn coal. i am talking about a fan to accelerate the process of burning the coal so i get lots more energy out of the coal but for a shorter time ill show a diagram,,,

Sorry for lack of detail it was a quick drawing

That looks fine, but I'd put your fan on the side blowing in at 90o.
-For hotter still, you could convert coal to coke, by "cooking" it in a tin on a coal fire. If you keep enough air out and get it very hot you drive off the volatiles and end up with a very high carbon fuel.

One question though, since presumably you've done this... What kind of container did you use to keep the "proto" coke from combusting? ( It's what always stopped me from trying it...I keep thinking I'll have to build a steel airtight box for the coal-under-process hooked to a vacuum source to suck off the nasties..)

A regular food can, "lidded" with sand/soil will do well enough, e.g. in the middle of a fire. Once the thing stops off-gassing, take out and let it cool.
Nice clinky-coke.

Also this is going to be quite small no bigger than a bean can
