Old school cartoon network bumpers/ in between shows scenery

Back in my childhood. I vaguely remember. Cartoon network having bumper/ in between scenes. From what i remember it was a tall building with a single fan spinning slowly in the wall on top with loud trump playing in the back round. This was only on for no more than 10 sec before the next show played. Does any one else remember this? I feel like this was right in between the power house era and cn city. Like a transition before fully committing to the switch to cn city.
