How LOUD is this card? I'm not a gamer or overclocker but I can HEAR the fan on my Ti4200.
I got this card a month or 2 ago when it was $160 after a $30 rebate. I'd read postings about how loud it was, and when I plugged it in I was amazed at how it drowned out the rest of my system. Now granted, I"ve put some effort into quieting my computer (Panaflo 80mm fan and a 120 mm Nexus fan, Seasonic Tornado power supply), but this video card cooler surpassed all of those fans combined. Additionally, it does not seem to be a very effective cooler. After a lengthy session of World of Warcraft my GPU temp as recorded by Rivatuner was 78 degrees celcius.
What I ended up doing was just buying a Zalman VF700-CU cooler and putting that onto the card. That immediately dropped my temperatures to 50 degrees idle and 57 degrees load. So for anyone who values his/her ears, I"d recommend either getting a quieter card or getting another cooler for this card. Be warned, though. Due to the positioning of the RAM chips and GPU chip on the card, I found it impossible to use the RAM heatsinks that came with the VF700-CU.
The redeeming factor of this card, in my eyes, is its impressive overclocking abilities. Mine is currently running stably at 569 Mhz clock speed, with the RAM running at 1.14 Ghz. Stock speeds for this card ar 500 Mhz for the chip and 1 Ghz for the RAM, and stock speeds for most 6600 GT AGP cards are 500 Mhz for the chip and 900 Mhz for the RAM.
I hope this helps some people decide!
