## What reviewers say

**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.
