Need some ideas about cooling my ultimate video card!!!

ok i got a hercules prophet 2 ultra and im thinking about ideas of cooling first of all i found this sandwhich blorb but it wouldnt worth on the ultra only the gts and i dunno how good a blorb is anybody have one ???????
i wana take my ultra from 250/458 to 300/500+
any ideas besides pelt and watercooling already changed my mind on that one!!

for you interested in dual orb here is link pretty cool i think http://www.ripnet-uk.com/dual-blorbs1.shtml

I run my Hercules GF2 Ultra at 270/500. The speed bump comes from increasing the memory speed. Overclocking the GPU does almost nothing at all. I have a 120mm fan in the side of the case and it does blow over the vid card and provides enough cooling to run the memory at 500 with the stock heatsinks.

anybody got a win2k reg edit file so i can oc my video card i dunno anything bout windows reg in 2k

www.pcpowercooling.com sells a pci dual card. Have not seem the Ultra, but I replaced my GTS Pro II with a Blue Orb.
