This versatile PC case fan measures 8cm x 8cm x 2.5cm (3 1/8" x 3 1/8" x 1"), designed to fit a broad range of computer case designs, helping to improve internal airflow within the computer case by circulating cool air into the case or exhausting warm air away from the computer. A quiet cooling solution, the 8cm dual ball-bearing fan features a high-efficiency blade design that's capable of moving 32 CFM throughout the computer case. This broadly compatible PC cooling solution can be powered through a simple TX3 (3-pin) connection to the computer power supply and is backed by StarTech.com's 2-year warranty.
