Lian Li UNI FAN SL-Infinity 120-1 Fan
The Lian Li UNI FAN SL-Infinity 120-1 Fan is a 120 mm case fan from Lian Li's UNI FAN SL-Infinity series. The 120 mm model measures 120 x 122.1 x 25 mm, runs on DC 12V for the fan and 5V for the LED, and uses a Fluid Dynamic Bearing (FDB).
It suits builders adding or replacing case fans who want lighting along with cooling, or who want to add one more fan to an existing SL-Infinity setup. The official specification sheet covers the whole SL-Infinity range (120 mm and 140 mm, single fans and 3-packs), so check the variant details on this page before you order.

Compatibility and related parts
Before ordering, check that your case has free 120 mm fan mounts with room for a 25 mm thick fan. The fan needs both 12V fan power and a 5V LED header, so confirm what your motherboard or controller provides. You can see other Lian Li products for matching fans, look through PC cases if you are planning a new airflow layout, or use the PC builder to check compatibility. Parts bought as part of a PC build get free assembly and testing.
