CPUs, GPUs, SSDs—all of them need cooling to various degrees, and some combination of heatsinks, fans, and cycled liquid will get the job done. But what about memory? When running at crazy speeds of 8,400MHz or higher, your DDR5 DIMMs can get pretty toasty. Cooler Master’s latest offering at Computex manages it with a tiny fan embedded in the stick. According to the announcement, this setup is “designed for next-generation AI computing, gaming, content creation, and professional applications.” The MasterDimm AC system can cool RAM by up to 15 degrees Celsius, while maintaining support for the latest standards like AMD EXPO for low latency and Intel XMP 3.0. This could be a huge boon to overclockers. Designed in conjunction with G.Skill, the blower fan (of unspecified size) maintains a noise profile under 35 decibels. The first packages will support up to 2x64GB capacities, which makes sense—you’re not debuting an active cooling solution for someone who just wants to throw a basic desktop together. But that will probably price it out of contention for all but the flushest of desktop PC builders. Hey, at least it’s more functional than more tiny screens . Desktop RAM at that speed and capacity starts at around $2,000 in the nightmare that is the 2026 consumer PC market , so expect these DIMMs with active cooling to cost as much as a used car when they hit retailers.
