The primary design considerations featured are increased surface areas, a low profle cooler, a slim cooler, a refreshed version of the NH-D14 and a new top end triple-stack cooler. All new cooler designs are aimed to allow tall, high performance memory kits with heatspreaders up to 70mm high (On either side, pointing towards LGA2011).
