thanks, I didn't know about the silent x issues. blowholes are good, as already stated twice. if the HSF is from the sides, rear and front mount seems the best option to me. one intake, other exhaust. continuous air stream across the unit will keep it cooler. the article I posted above is extremely useful for airflow
