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.)
Praised: Daisy-chain Uni Fan cabling drastically reduces the number of wires to route and hide when installing several fans.
Flagged: Controller box requires a six-pin PCIe power connector (plus SATA for stability), hard to spare in GPU-heavy builds; LCD and non-LCD TL fans cannot be mixed on the same daisy-chain to the controller box.
