Microchip Fans: A Breakthrough in Cooling Data Centers

Swift Summary

• Pluggable optical transceivers are vital for data centers, but generate significant heat due to power consumption (40 megawatts in a center with 400,000 GPUs).
• Startup xMEMS Labs has developed a MEMS-based “fan-on-a-chip” cooling solution designed to fit inside these transceivers and cool their Digital Signal Processor (DSP).
• Cooling improves DSP longevity and signal reliability, reducing issues such as extended AI model training times. Each transceiver costs about $2,000.
• The MEMS tech is compact, using piezoelectric materials to drive air through the chip at ultrasonic frequencies (pumping 39 cubic cm of air per second).
• Production silicon for the MEMS chips is expected from TSMC by mid-2024; full production starts in Q1 of 2026.
• Transceiver market growth: Shipments predicted to increase at over 35% annually until 2028 according to Dell’Oro Group.
• Competing innovations include power-efficient DSPs from Broadcom or network switches adopting “co-packaged optics” that eliminate pluggable transceivers.
