From that diagram you'd be getting a serious amount of negative pressure ... I'd reverse the 60mm fan at least... my general principle is to try and match the input CFM with the output CFM.

Negative pressure makes the fan work harder and therefore creates more noise/vibration shortening it's useful lifespan.

If you can add another input fan that would be a start. The larger the better.
