CFA-300 - 80 or 92mm to 120mm Fan Adapter
Get more or quieter cooling for your 80 or 92mm solution!
Most cases and some heat sinks are designed with 80mm or 92mm fans. 120mm fans offer the same airflow at a much lower RPM, resulting quiet operation. They may also offer much higher airflow at the same RPM, resulting in better cooling. This adapter will allow you to mount a 120mm fan on a place designed for 80mm fans (if room allowed).
