I would love to see some empirical evidence showing that running a fan at it's rated voltage continuously shortens its life vs running it at @ rated voltage but controlling speed using PWM.
You don't want to run your fans at 100%. You will burn them out quite quickly. They are not designed to handle that. You shouldn't have to run your fans greater than 70% to stay in safe operating ranges. 60-65% should be more than enough. If you do have to run them that fast you are pushing your cards too hard or your ambient temp is too high.
^^I'd say 750ish MHash depending on clock speed. One BTC every 3-4 days.
750 mhash is something like .63 BTC per day on average.

Common sense. Your wear quotient increases the closer you get the limits of anything that is mechanical or electrical.
Isn't that assuming a 24-hour crunch? I was factoring in the 12-16 hour frame.
Will there be other people in the room that you don't want to force the fan to 80 or 100%?

I've found weird things happen if you try to run Trixx and AB at the same time.
I think that is fine. I generally consider under 80C to be okay. I might pay more attention if I had any expensive mining cards such as 5970s 6990 or 7970s, but I don't worry too much when my 5930s run close to 80.
Since you have a few rigs set up, figured I'd ask you. Is there a way to set up a script or something that will send me an email when mining has stopped for any reason?
I think BTC Guild will send you a warning if a rig stops reporting.
It's been a while now since the Bitcoin craze began... Is there a better Miner for NVidia GPUs now, or are they still basically pointless?
On BTCguild, you would earn exactly .62/day after fees. I know this because BTCguild is now entirely share based earnings, so you earn at a completely consistent rate, unlike most pools where earnings are based on actual coins minted and thus random. The fees are a little higher than most pools, but I find the non-randomness to be a huge plus, I am earning my bitcoins at a very consistent rate.
What's the formula to calculate .62/day with 750mhash?

Can someone help me with diablo miner? It's not very intuitive. My 6870 is mining on it but I lost 30 MH/s compared to Guiminer. How do I enter in the appropriate flags?
Edit: Nevermind, I figured it out. How do I tell it to use two GPUs though?
I am seriously thinking about giving this a try. So with the current bitcoin market, what kind of production could I expect to get out of my 2 unlocked 6950s? Any guesses what I could expect running full bore 12-16 hours a day?
Does bitcoin mining generate enough internet traffic to make your ISP think you're running torrents 24/7? Thinking of giving this a try with a spare PC if I spruce it up a little with a decent graphics card. Only has an Intel 478 cpu, tho. Not sure if that's good enough. Seems like this is a fairly risk-free thing to just "set and forget" (while checking it every now and then to make sure that it's running...).
My OCed (860/200) _locked_ 6950s get 350MH/s. I get about 2.9 coins/day with my total hashing power (~3700MH/s) at the current difficulty.I am seriously thinking about giving this a try.
