I see nhancer discussed in this forum, I've heard of rivatuner, and nvhardpage, and ntune. Are all these competing products for the same purposes?If so, I see Nick N is discussing nhancer mostly, is that the general consensus as the tool to use for establishing optimal performance from my (still in the box) evga 8800 gts (g92) 512?I've read that fan speeds are oddly locked at 30% on some nvidia cards and we need one of these utilities to unlock..yes? And is this done thru nhancer also?Bob

Nhancer is for controlling the cards render abilityRivatuner is for controlling the fan speed and overclockingSome drivers do not like Rivatuner for clocks, I use ATI Tool (believe it or not) for clocking the card ONLY, Rivatuner for total fan control and Nhancer for the render settingsall three are free, all three do a good jobAll these programs are set up for complete automatic operation.. my fan is variable from 35% to 100% depending on the temps I personally set up. ATI Tool automatically overclocks when i start FSX (or any 3D app) and underclocks when I close itThis makes everything automatic and easy.. RivaTuner a PITA to initially set up because its a bit complicated on fan control however the rest is fairly strait forward.

thanks Nick! Excellant help.

CAREFULL with RivaTuner.. If you dont set it up it can LOCK your fan at 35% and overheat the cardHere is the RT Fan control setup guide.. like I said, its a PITA but its the best one out there for great control of a Nv cooler fanhttp://guru3d.com/article/article/449/I use 13 custom temp points so my card is VERY quiet at idle (cant hear it at all) and spins up/down with a lot of variation based on load

lol!my default card settings were fan: 29%!!I used rivatuner to up that to 50% fan speed

I use 13 custom fan profiles that trigger by temp increase/decrease so I dont have to do anythingdead silent if i am not using 3D and keeps it perfect below 72c fully clocked under a loadI also use this cooler http://www.thermalright.com/new_a_page/pro...oler_hr03gt.htmwith a 90mm PMW fan I wired to plug into the card directlyhttp://www.newegg.com/Product/Product.aspx...N82E16835185048

Nice cooler, mine running @ 50%, with HalfLife 2 Ep 2 runs right near 60C, that's after about 2 hours of constant HL2....It's actually a decent cooler on the gpu, IMHO:http://www.newegg.com/Product/Product.aspx...N82E16814127329Hey, how do you set fan profiles per temperature?

Just follow the directions for custom fan control setup in the link I posted above for RTThey show an example.. I just expanded on that and setup 13 points between 54c and 80c to increase and decrease fan speed. The only time I see 70c+ is if I am really nailing the card in the middle of the summer. Otherwise it sits between 62-68c. That is overclocked till it screams too. LOL
