Phison PCIe 5.0 E26 Drives Are OK Passively Cooled

“The E26 and newly launched E31 mainstream PCIe 5.0 drives will need passive cooling, and the standard motherboard heatsink should suffice as long as you have any airflow in the case. The E31 will launch in Q1 and offer 10.1GB/s read and write, and with the future NAND, one can expect 14GB+ speeds.

What happened with early PCIe 5.0 reviews was that our colleagues were testing on the desk workbench without any airflow, and such a scenario can result in throttling and overheating of the M2 PCIe 5.0 drive. As long as there is a normal intake and exhaust airflow breeze through the case, one should be fine.”
