How hot can a 670 run safely?

Hi everyone!

Recently I have had to move my rig into another room, as I am decorating my bedroom. The room it is now in is quite small, and so heats up quite quickly after turning my PC on. (Usually about 10 mins and I have to open a window. =P). I habitually have temperature monitors running along with other monitoring software that starts up automatically on boot, as I like to keep an eye on things. I have become somewhat concerned with my GPU temps after the move. I am currently running 2 x EVGA FTW 670's. When running intensive games, (The most intensive so far being Crysis 3), my temperatures go above 70 degrees, nearer to the 80 degree region. If I run a grpahics benchmark, such as Fur Mark, then my GPU temps go above 80 degrees, and max out at around 85-87 degrees. Before anyone asks, I have already maxed out the amount of chassis fans I can fit to my case, and I have created a custom fan curve on EVGA Precision X which ramps the fans up to 100% upon reaching 70 degrees. I have also quite heavily OC'd both cards, and now each 670 runs at around 25-30% better performance than a stock 680, so I understand more heat will be generated than a stock 670.

I realise that GPU technology has improved, and so GPU's can run at quite high temps, but my own personal 'max' is 75 degrees, as I believe this to be the highest safe temperature. Is the fact that my cards are running so hot something to be concerned about?

Thanks in advance for any help!

Thanks for your replies!

I thought that it wouldnt be anything major to worry about. I was aware of the boost clock being limited by the temperature, but to be honest because of the level of overclocking on the cards I dont really notice much of a difference when the boost is on or off. =P
 
The maximum GPU threshold is 97c.

Here is how the temperature impacts Turbo Boost clocks on the GTX 680 (similar to the GTX 670, but the 680 has slightly higher clock speeds at each increment).
