Mushkin's Frostbyte heatspreaders are designed to keep the modules cool under fire with the wide flow path for airflow through the modules. Even with 1.7 volts through them, they remained just barely above ambient temperature under load. Airflow of course helps to keep the Frosbyte heatspreader working more efficiently. With Mushkin's Lifetime Warranty, hand tested modules, and competitive pricing and performance, this set of modules will give you a ton of overclocking fun for your hard earned cash.
