Is it Ok to control your fan speed using SpeedFan on NF7-S

I was considering switching from MB5 to Speed fan because I like the ability to control your fan speed through the software. I was wondering if anyone has had any problem with using the software on the NF7-S and could this hurt the MB in some way?

I would like to control my CPU fan (Panaflo 92x25 High speed) with the software, this way I don't have to worry about the family members turning off the CPU fan with a conventional fan controller.

I figure its better to ask then be sorry

Yeah, it's OK, IF the program works well on your board.

I used it on my Asus A7N8X-Deluxe with no problems at all.
With my NF7-S the range of fan speeds is completely whacked out....really works poorly.

What to do mean by "wacked out", are you not able to reduce the fan speed or is it just erratic?

On my NF7 the fan speed doesn't start decreasing until around 40%. You don't have as precise control as a rheobus, but Speed Fan works.
