BFG 9800gt passive with hr-03 rev.A - need how much airflow?

I just picked up the passive BFG 9800gt. Newegg link for reference

This will replace my passive Asus 7600gs.
I know it's a power hog with the old 65nm process, but for the price I was getting it ($47 after rebates), I couldn't resist. But now I have to worry about cooling it ... quietly.

My current setup includes:
C2D 2.4 @ 3.0ghz with 1.22Vcore. 35C idle and 44C load. 28C case temp.
Scythe Ninja Rev B with Scythe Slip-stream 12L @ 800rpm in idle and 1000rpm during load.
Scythe DF12L @ 550rpm as rear exhaust.
Ultra x-finity 500w power supply with 120mm fan.

Anyone have this card or a modded a 9800gt with a Thermalight Hr-03 Rev.A? Will the close proximity to the CPU fan be enough to keep this card's temperature under control?

If not, then I'll have to try to mount a 120mm onto the card w/ strings or cable ties. I am asking now so if I do need the fan, I can buy the fan now and have it arrive at the same time as the video card.

Anyone know if BFG voids warranty if I flip the cooler to be 'upright'? If I have to add a fan, I'd rather have the fan blow into the card and cool the VRAM at the same time.

Current setup. (excuse the messy cabling! I still live in the olden days of ide cables :D)

Got my card and updating with new temperature numbers and pictures!

The setup was fine with my existing fans. The GPU HSF does a great job cooling the card. I was able to maintain my fan settings.

temperature (delta temp):
CPU: 41C idle (+6), 49C load (+5). (Linpack)
Case Temp: 30C (+2)
GPU temp: 44C idle, 59C load (Furmark burning)

I am very comfortable with these temperatures. :)

Perfect match!

VERY sweet setup !!!
also, greats temps considering you have just one fan getting the heat out of the GPU and the CPU !!
