Questions on speedfan and a fan controller purchase

Hey all.
Some background if you care:
I've just gone to my local micro center recently(like fry's I'd suppose- never been to that though) and purchased some very nice scythe fans to pair with the stock antec ones I've got in my antec 300. I've got two of the 120mm 1900rpm s-flex fans (34 dBA @ max rpm) on my intake, the stock 140mm and 120mm antec exhaust on the top and rear, respectively, and a nice 120mm 38mm-thick ultra kaze on the side panel @ 1000 rpm and 20dBA.
Since adding these fans, my stock E8400 idles @ 30C, and my asus EAH4870 1gb gaphics card idles in the mid-high 30's C. I'm very pleased. However, these fans seem very good @ moving lots of air with moderate noise on the high rpm end, and also seem to run very quietly @ lower speeds.
Issue 1:
I'm a long time user of speedfan to keep fan speeds+noise inline with temperature of components. Before getting my current 4870, I had a nvidia 7600gt, and speedfan would pick up a reported temp for it. It doesn't pick up any temperatures on my 4870, which would be great- as I could tie the ultra kaze on my side panel to the gpu temp, since the thing is mm's away from the heatsink on the card, and does a good job of getting air to my dark knight. Anyone know of a setting somewhere to do this? Or is speedfan just no up on current ATI sensors?
Issue 2:
I've run out of fan headers on my motherboard for these new fans. The 120 and 140mm antec fans are those tri-cool fans which connect to molex and have a 3-speed toggle switch to choose h,m,l. I've run those two switches out of an expansion slot so i can just reach behind the case and control those fans. But, with my new fans I've got the u-kaze on the side plugged into a header, my psu on the 'pwr' header, and an adapter (yellow wire only) from one of the intakes on the remaining header. I've done this because botht he front fans seem to run @ the same speed, and a report of the speed for one seems sufficient. I can't control the speed though. So I'm looking to buythis controller .
I've never used a fan controller besides the zerotherm one that came with my nv120 cpu cooler- so I've got little knowledge about them. Does that one seem good for controlling 2 120mm scythe s-flex fans? I know some fans are a bit hinky about voltages from controllers- but I haven't a clue how to determine if that'll be my case or not. It's important to not lose the cooling power of my system (as I game and live in a dorm most of the year where it can get warm, and during the summer live where it is hot+humid), but at the same time, I live in a dorm w/ a roommate, so I like my computer to be silenter(er) when nothing intensive is going on.

Sorry, I guess I wasn't all that clear in my original post: My graphics card is awesome at cooling/fan/noise performance on its own. If my system is idling, ATI's catalyst will run the fan @ 31%, which is silent for all intents and purposes. Gaming sits around 50% (which would be acceptable noise levels @ idle IMO, and is therefore super for gaming) , and gpu-folding goes to 50%, 60%, and sometimes 75% if the room is hot. Those fan speeds are on my ASUS EAH4870-1GB, the dark knight edition, and I feel their cooling solution is far superior to the stock solution (though it gets the best cooling when a case has a positive pressure- which many people don't typically use/have)

But, I've added a fan on the side panel of my case- an intake, which points right at the graphics card. I change the speed of that fan with speedfan, but speedfan doesn't pick up any of the ati sensors, so it's a manual change of that side fan that I've been performing.

I read a bit, and it seems speedfan cannot currently read 4800 series ATI sensors, and I'm left leaving the fan to manual operation.

Good to hear the controller is a good choice though- thanks for the input
