Cooler running electronic components such as memory chips last longer, so why not consider watercooling the RAM in your PC. These watercooled memory kits include a set of DDR4 DIMMs of varying capacities for desktop PCs, plus a waterblock that attachs to the DIMMs. Plumb this into a watercooling loop and you could lower the memory temperature by as much as 37%. The waterblock also includes a programmable RGB lighting system for extra standout.
