5 Things to Check Before Buying RAM for Cooler Clearance

Measure your cooler’s RAM clearance Check the gap between your CPU cooler’s bottom edge and the motherboard. Compare it to the RAM’s height spec—tall kits are usually 40-50mm, standard is about 32mm.

Look up your cooler’s RAM clearance spec Most air coolers list a “RAM clearance” in millimeters. If the cooler overhangs the RAM slots, tall heatsinks won’t fit under the fan.

Check if your AIO pump block clears RAM Liquid cooler pump blocks vary—some are offset to avoid RAM slots, others aren’t. Look up your specific AIO model’s clearance.

Know your options if RAM doesn’t fit Move the fan up (reduces case compatibility), use low-profile RAM, or check if the cooler has a cutout for tall modules.

Don’t guess the fit Guessing leads to a fan resting on a heatspreader and a system that won’t boot. Measure or verify specs before buying.
