I have a 7600gt and I'm looking to ditch the stock fan as it is quite loud. I have been told that the zalman vf-700 cu will fit this card, as will the arctic cooling silencer 5 rev 3. First of all, is this correct? Will the accelero fit? So if my options are the vf-700 or the silencer 5 rev 3, which would people recommend and why? Also, I know the 7600gt is already clocked pretty high so there's not a lot of overclocking room, but if I get one of these coolers will it help me OC? My temperatures are fine right now, but when I try to OC using coolbits, it fails testing once I get up to over 605 core and around 770 memory (from 580/750). Will a new cooler help it to pass the coolbits tests, or am I at a physical limitation? Thanks for your help.
