A quote from the article:
It's no secret that this chassis overall temperatures is higher than most of its competition. The fact that it's a compact mid-tower plays into its overall temperatures and airflow.

Some of this can be resolved by removing the top hard drive cage to allow larger video cards and or more space for the card to breath. The simple fact that the chassis airflow is limited because of the low RPM pre-installed fans is the main reason for this.
