HOWDY! :D I have a few questions and was wondering on what games would SLI be best to use it. The games i play are Skyrim, Starcraft 2, Crysis 2, World of Warcraft, and the Diablo 3 beta. And is it ok to have SLI enabled at all times or is it best to just turn it on when needed? 
 
Also had a question about temp's in SLI. Playing Crysis 2 fullscreen, 1920x1080 on high settings was getting into 58-64c range on my top card , and 38-40s on the bottom card without SLI enabled FPS seemed solid. Just wanted to know if these temps are decent for the settings. I've enabled SLI ( But not payed any games yet ) as i was writing this and desktop temps ideal are 40c card 1, 37c card 2. My mobo says case ambient temps are 19-20c at desktop as well.
 
Also had a question about power consumption. Do these cards pull their full watts at all times? or only when under full loads I forgot the recommended PSU for a single card. Based on the performance increase I've seen even without SLI enabled I'm glad i stuck in my 2nd 470 in, instead of just letting it sit on my table lol.
 
I just wanted to get a few things brushed out before i started playing around with anything. Want to get my settings right. Im running EVGA precision ( Not the new updated x version ) have a more aggressive fan profile  but i'd like to also know if there was a point of diminishing returns in regards to the fan speeds.  
 
I have them currently at these settings  
30c = 45% 
35c = 55% 
45c = 65% 
55c = 75% 
65c = 85%  
75c = 95%..  
 
65c is probably the max temp I've ever seen and that was playing Crysis 2 today. I sit mostly around 50s-58c in my other games. Are these settings ok? or should i move them around a bit.. tbh they're really loud and I'd like to know if i could bump them down a bit  and still be ok temp wise. Looking for a balance between good air flow and less noise lol if that makes any sense.


Thanks for all the help here guys, i know its a lot of questions all wrapped into one post but i'm finally getting the performance out of my rig I've been wanting and trying to polish it off :)
