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.
