A very convenient solution to connect a plethora of fans, LEDs and temperature sensors. And there are two additional internal USB headers on top of that. The LINK software works great for me, I did not encounter any bugs so far. Helped a lot with cable management in my last build.

Buggy software is buggy. Fans would randomly ignore my custom curves and sometimes just stop spinning(I've had this happen in the middle of a game on multiple occasions). Closing the Corsair service and attempting to restart it would sometimes result in the service not starting at all, forcing me to restart my PC entirely.

Enough connection points for all my fans, LGB lights and thermal wires. LINK Software needed but it worked very well and user friendly.

Awesome piece of hardware, I control half my fans speeds and all my lighting throughout the case for the exception of the motherboard. Was a little tricky getting it setup as you have to upgrade the firmware right out of the box and you have to add each fan individually to your setup and no it doesn't auto detect until after you add each fan and each light strip.

Super easy to install and use. With the Corsair Link app, it pulls in all the fans and temperatures in the case. Will also pull in Corsair fan RGB and Corsair RGB strips. Great for controlling all the fans and being able to assign each fan to a corresponding temperature. Again, my only con is not being able to control all of the RBG in the case with the Link app.

It's a little big, but I had room for it. I kind of had to get it so that I could use all my fans. It does the job.

On my third controller when it works is great but eventually it will die on you and there is no way to get it back to life.

works nicely and very convenient. Helps to bring cable management together.

Aaaahh the commander pro. Totally useless therefore utterly indispensable. Had to have one of these to make the RGB fans "sing" in sync.

It has a lot of wires so be prepared to be good at cable tidying.

Expensive but necessary lol
