FC5V2 is an excellent fan controller - I used it for quite a while and loved it.
If money is no option and you're a control freak - Aquaero 5. Avoid it like the plague if you're impatient though, it's got a steep learning curve.
Nice fan controller:thumb: but I just don't see the point in spending that much on a fan controller. Plus I prefer a more elegant look. You are right though money better be no object for those Aquaero 5s
