## What reviewers say

**Noctua NF-A12x25 G2 PWM** — Two whitelisted outlets ran hands-on, measured tests of this exact 120 mm fan: TechPowerUp (a dedicated multi-page review) and Tom's Hardware (a head-to-head against Arctic's P12 Pro). Both rank it among the best-performing and quietest 120 mm fans available, with the only recurring criticism being its roughly $35-per-fan price. (1 sourced review.)

**Lian Li UNI FAN TL 140** — Only one whitelisted tester covered it: Tom's Hardware's hands-on of the UNI FAN TL line, mostly the LCD variant, with no cooling or noise testing. It praises daisy-chain wiring that cuts cable clutter but flags six-pin PCIe power and being unable to mix LCD and non-LCD fans in one chain. Exact TL 140 lab tests fall outside the whitelist. (1 sourced review.)
