Installation was fairly easy, though cable management was a bit of a mess. What impressed me the most during installation was that each connector on both the fan and temperature sides were clearly labeled with a number. I ran into an issue with the Sentey Arvina case that I am using in that the case fans were pre-wired to a controller at the top of the case. I had intended to just reroute those fans to the Sentry LXE, but discovered that the case fans used a 2-pin connector. I ended up swapping a couple of the fans out with others that had 3-pin connectors.
I placed temperature probes in three locations of the case: one on my primary data drive, one on my GPU, and one near the CPU. A probe right on the CPU heatsink wouldn't be a bad idea, but it really boils down to what you want to measure and where you might typically have issues.
The instructions for operation are very simple so I won't include them here. It is also possible to set an audible alarm if temperature probes reach a certain point. It doesn't specifically mention this, but I wanted to see what happened if I disconnected a fan while it was in use simulating failure. That triggered the alarm as well, which is a beeping sound from a speaker on the card.
As I mentioned above the touch screen is very intuitive and easy to use. I had two fans used for testing due to the other three being the wrong connector. For long term use I would have simply re-wired them to work. The temperature probes gave a nice view into the different zones of my case.
