xMEMS introduces µCooling for SSDs, enabling in-drive active cooling

xMEMS Labs, Inc. announced the application of its µCooling fan-on-a-chip technology to solid-state drives (SSDs), introducing in-drive active cooling for enterprise E3.S form factor SSDs in AI data centers and NVMe M.2 SSDs in laptop PCs. The technology uses a monolithic silicon MEMS air pump to provide cooling directly to NAND flash and controller ICs within the SSD.
Traditional SSD thermal management relies on passive heat spreaders and system fans, which struggle to handle heat from sustained workloads in AI, high-performance computing, and modern computing environments. As SSD speeds exceed 7 GB/s, thermal throttling limits performance. µCooling delivers localized cooling to mitigate this issue.
In AI data centers, E3.S SSDs operate at 9.5W TDP or higher, creating thermal hotspots in dense racks. Thermal modeling with µCooling shows 3W of heat removal, an 18% average temperature reduction, and a 25% decrease in thermal resistance, enabling sustained high-speed I/O, improved reliability, and better throughput for AI/ML workloads.
For consumer laptop PCs, NVMe M.2 SSDs face thermal limits during large file transfers, sustained writes, or gaming, particularly in fanless ultrathin devices. µCooling integration results in a 30-50% power overhead allowance, a 20% temperature reduction, 30% lower thermal resistance, and a 30% lower temperature r...
