  • Great fan(see note for 207 digital installation)
Style: SLIN140 Single Pack Black
Great fan,bought it for a lian li lancool 207 digital case.Please note if your buying it to replace the bottom fan in your 207 digital case you'll need to modify your installation as it will not fit due to the wires blocking installation.Youll need to loosen up the wires for your top fan slide it down to the bottom of the fan position then install it as the 207 digital case has a notch cut out at the top of the case (the metal mounting slot) then it will fit without issue.That was the easiest least annoying method for me. ... show more

  • Love these fans
Style: SLIN140 Single Pack Black
I love the look and quality of the SL infinity fans. I had to replace the two 140mm fans on my Lian Li CPU AIO cooler due to bearing failure and went with these to match 3 other SL fans in my case. I love how they connect without a cable to each other but wish they had a better cable to plug into the SL controller. Luckily I had a cable that worked that came with the controller. The customization and the looks of these fans are really amazing. ... show more

  • High end PC fans
Style: SLIN120 Triple Pack White with Controller
Really great fans. They are pricey but you get what you pay for. It elevated my PC build and fit perfectly in my NZXT case. I mixed these fans with the Lian li LCD fans.

  • Fans are great - ecosystem is a pain.
Style: SLIN120-R Reverse Single Pack Black
Have a bunch of these fans (3x on AIO rad, 3x on bottom of case, and 1x exhaust) + 3x Lian Li's TCL LCD fans + 2x strimmers. The fans themselves are excellent and work solo or in a daisy-chained group (which is the primary feature of these fans - they fact they snap together without need for additional wires). They look fantastic, especially when they're lit up - the infinity mirror center is awesome. The ecosystem though is a bit frustrating to get set up and working together. Single fans come with different connectors than the daisy-chained 3 packs. Everything needs to be hooked to Lian Li controllers that only come with the 3-packs. Controllers can't be daisy chained and each type of fan (SL INF - these ones - TCL and the UNF/AIO fans) need their own separate controller - which means your USB bus is too flooded with nested connections and you need to use a separate USB cable routed through the back of your case to your motherboard's I/O instead of using USB headers (which you likely don't have enough of). Lian Li sells a power supply that helps solve this issue, but it's also an issue they've unnecessarily created. Overall, great fans.. but the ecosystem took forever to set up (actually get working flawlessly), requires too many cables and controller boxes, and requires a workaround of routing a cable outside your case). The software also isn't the greatest. I'd do it all again, simply because you only have to do it once per PC build - which should be once every 4-6 years. However, there's no doubt Lian Li has complicated what should have been a simpler solution. ... show more
