Terms used on this page

CPU cooler height
The installed height of an air cooler from the motherboard, compared against the case's published CPU cooler clearance. Coolers at or above 160 mm exclude many compact Micro-ATX and tempered-glass mid-towers.
RAM clearance
The tallest memory module that fits under an air cooler's front fan in its stock position. Dual-tower coolers with less than 42 mm clash with tall RGB kits (typically 44 mm) unless the fan is raised.
Dual-tower air cooler
An air cooler with two fin stacks and a fan between them (often a second in front). Highest air-cooling capacity, but the front fan overhangs the DIMM slots, which is where RAM clearance limits come from.
