Traditional computer fans are made to expel air, so for years, airflow was the most important rating that determines cooling efficiency as most fans are used as exhausts. SilverStone created Air Penetrator fan specifically designed for intake fan applications, where airflow rating is not a priority. The design goal for Air Penetrator is to focus airflow into a column that can be channeled through various obstacles inside the modern computer case for more efficient cooling performance. Compared with traditional fans, where airflow spreads outward and further looses focus with resistance added (e.g. filters, fan guards, etc…), Air Penetrator fan’s unique blade and grille designs can create enough pressure to push air as far as 1 meter away with minimal fan speed and noise. This unmatched efficiency makes Air Penetrator ideal not only as intake case fan, but also perfect for high density heatsinks and radiators.
