Old friend sweating again

Hi all, nice to meet you
So it has been about a week since my old friend GTX 260 joined Einstein@home. I kept this thing in dark corner for almost 3 years. One day of all a sudden I took it, plugged into second PCI-E slot and surprisingly, it still worked. I was wondering if it could do some useful work until it becomes completely useless and found Einstein project. Yet this old guy is still doing a lot better than my quad-core Ivy Bridge CPU. But it’s sweating a lot - temperature goes up to 85 degrees.
So what is maximum safe temperature for GPUs? Should 85 degrees considered too high? What about your GPUs?

Is that 85F or 85C, it makes a big difference, if it's 85F then all is good, if it's 85C you NEED to point a fan onto that thing as that IS hot. I have several gpu's, not a 260 though, and most run in the 60 to 70C range when crunching.
it's 85C. there's one fan

it's 85C. there's one fan blowing inside, right below the GPU and at left side of the case. would you suggest me adding another fan inside the case?

Actually I was thinking more of an outside fan blowing into the case, I have had to do that on several boxes that just get too warm. It sounds to me like your gpu might benefit from some under-clocking as it is generating alot of heat. I think you can use the software MSI-Afterburner, but you will have to ask others how to do it, I think your cards fan is just not removing enough heat any more. This can happen due to a poor case design, poor gpu fan or even gunk build up inside the fan.
Have you looked at the

Have you looked at the onboard fan to see if it is turning. If so how about getting a can of compressed air and blowing it out (remove it from the case - you don't want to do this powered on because cold air coming from the can might condense humid air and cause a real problem should you live in a humid climate).
If you are using Linux there is a way to "uplift" the driver to provide a fan speed slider so that you can increase fan rpm and cooling. On Ubuntu Linux you can do:
1. sudo nvidia-xconfig --cool-bits=4
2. reboot
3. launch nvidia-settings from command line or from the "Dash Home".
4. click on "Thermal Settings" for your GPU.
5. Note the "enable gpu fan settings checkbox" and the fan slider.
The above does come with risks so you need to check the temp until you are satisfied that all is well.
With some of my NVIDIA cards I have had to add side mount/top mount fans to provide sufficient cooling.
