## What reviewers say

**Phanteks T30-120** — Only one whitelisted hands-on source survived verification: Tom's Hardware (Aug 2021), which found the T30-120 to be the first fan to beat Noctua's NF-A12x25 on noise-normalized airflow, aided by its 30mm thickness. It praises the switchable operating modes, build/construction quality, and daisy-chaining, while cautioning that the extra thickness can hurt case/radiator fit. The TechPowerUp entry was dropped because the fetched page returned only the review's introduction; none of its cited quotes or measured test values (which live on later pages of the paginated review) could be confirmed in the retrieved text. (1 sourced review.)
