Control individual chassis fan speed for ASUS P6X58D-E?

I'm looking for a way to set the speed of a chassis fan (3-pin) connected to my ASUS P6X58D-E motherboard. Anyone have any suggestions on how best to do this?

I have tried ASUS' Fan Xpert, and it doesn't work for me at all: there is only the option to adjust all chassis fans at once, and even then there are only three presets that you can choose from (Standard, Silent, Turbo). It seems pretty much useless to me, but if anyone can tell me how to get more options out of it, I'm all ears.

I've also tried SpeedFan and, while I think I have it set up properly, it doesn't actually change the speed of (in my case, the Aux2) fan even after going to the Configure / Speed and making adjustments, and then checking the Automatic fan speed box. Although, the program is not that intuitive and there's probably something I'm missing.

I don't really care what program I have to use, but I just need to change the speed of one of my chassis fans and have those settings be applied at boot up.

From what I've read about Asus boards with QFan, the 3 pin headers are not controllable. Your best bet would be to get a fan controller and hook your fan up through that.

ASUS Q-fan does a good job controlling my 3-pin fans, but only to a certain point. The fan speeds adjust as needed by temperature.

If you want to be able to adjust them at will...get a good fan controller.

Weird. The manuals for my M4A785TD-M EVO and for my M4A785-M say that Q-Fan only works on the 4-pin header; only the CPU fan changes speeds. In my HTPC (uses the latter board) and my parents' computer (uses the former board), the case fans are hooked to the 3-pin headers and run at a constant rate. In my own desktop (which is using the EVO board), I just have a fan controller.
