headers melted stock fan, i need a slim size/brand to go with
 

hey so i have the speed daddy headers, one of the stock fans bracket melted...
anyway need to figure out what size fans do i need i think i have about 15.25 inches on the radiator, stock radiator should i go with 14" or is that too close and get the 12"?
seen something about spal fans on youtube crazy power but veryyyy xpensive. trying to avoid that if possible.
so if you no of a fan set that would be a plus..thanks in advance
