Once you use a SPAL brushless fan you'll never be able to use a brushed fan again! Compared to a typical 2-wire fan, SPAL brushless fans are nothing short of incredible! 
They have built-in soft-start to eliminate inrush current typical with brushed fans and once singing at full speed you'll know it! 

Each SPAL fan requires a specialty connector (easy add-on during checkout) and requires only that you connect directly to battery.
