Sooo, I was cleaning my rad thoroughly for the first time in 2 years and dust and dirt wasn't going away with just water so i picked up a dish brush lying beside and very lightly scrubbed the fins where dirt was stuck. Now I want to bang my head on the edge of my desk. I didn't apply much pressure at all, but the fins are more fragile than I thought. I have 2-3 spots about 2 inches long where I bent the fins. I read that bent fins aren't a big deal as long as airflow isn't too obstructed and the solder points are still fine so I straightened them a bit with a toothpick and the solders seem fine but I won't know until I plug it all in again. From what these pics show, should I be worried?
