Whats a good target temp for mining?

[tospace]

I recently got a dual fan 5850 (with a cleaned heatsynk). I'm trying to not run the fans too fast because I hear they go out quickly on the dual fan ones, one of them already rattles in certain positions when I got it but it was supposedly underclocked and used in lan party computers

Right now I have clocks at 920/500 and auto fan speed so its running at 88c/78% fan speed pretty constant right now.  I'm not sure what I should do on a costum fan curve if any.  I could lower the fan speed 10-15% with it costing only around 5c maybe so I'm just trying to get a good balance. 

So yeah, I just want to know what the highest temp I can run my card at constantly for a few years  .

Thanks

i stay cards at 70C. this is good temp and makes cards last, but fans don't.

I wouldn't run it nearly that high. I make sure mine stay below 70. You're quite right to worry about your fans. The best solution I found was pointing one of these across a row of cards. I got one for each machine:

That said...you're not going to have to worry about running them for years. Maybe the next 2 months if you're lucky.

i think asic will come not this year, but next.

Not sure if that really matters to GPU miners. Difficulty is currently estimated to go up another 12+% in 3 days. We're running out of time.
