Generally speaking, adding fan filters of any kind will increase airflow resistance and often results in decreased cooling performance. SilverStone’s FF125 aims to mitigate this deficiency by drawing upon the HiFlow Technology filter created while developing the RAVEN RV04 and Fortress FT04, two of the best cooling cases made in SilverStone’s history. Compared to the FF122, an already high quality computer fan filter, the FF125 is capable allowing 20% more airflow while maintaining the same dust filtering ability. For those looking to install a fan filter while keeping maximum possible airflow intact, FF125 is the best option.
