Why heat spreaders on RAM don’t matter—for now

You should take their height into account when planning a PC build, though.

System temps weigh heavily on many builders minds. If not for practical reasons, like maintaining longer lifespans for components, then for the sheer enjoyment of optimization. Most people focus on CPU and GPU temperatures, as those heavy hitters are expensive to replace, but some folks also come to wonder about other parts—like RAM. Generally they wonder about the passive heatsinks on memory modules, and if bigger heat spreaders are better for keeping RAM cool.
