Nothing to talk about the LXE actually...
The only unique this is , the screen and the whole body isn't mounted onto the Case , but you can put it on your table or other places that you want to monitor your fan speed , temperature and etc.
If not , the Sentry 2 or LX is already okay...
Bigger fan size = more Air flow , also , they run more silent than 2 x 140.
If your case can support 2 X 140 , sure.

better go for lamptron fc touch. can control 6 fans with individual manual or auto settings.

Yup , it's more off a Sentry 2 or LX.

But I've heard a lot of reviews that , it's hard to basically change the speed to 100% fan speed using your fingers , need to use much smaller object to ramp it up to 100%.

havent got any chance to use it yet though i really looking forward but here is a video that might helps

yup he is talking about the lamptron fct but thats not a big problem as there are + and - button u can use if u find the adjusting level too difficult.

unfortunately i do not have anymore info to tell u than what i have read and saw on the net. but form what i read it is a good product and value for money too. except for some flaw(i mean which product doesnt come with flaws at all)

Post up some pics when you mount up the controller
