When I bought my graphics card about 18 months ago, I was given Zotac Firestorm on disc to install at the same time, which is very good at viewing your GPU temperature, and doing a few other things. When I get to about 64 degrees then I can hear the fans start to work, I don't think I've ever had a temperature over 70 degrees yet, with any PC game I play, so, if you go above that then you need to monitor things closely.
I think you can download a free version on here, of course, there may be other similar tools that do the same function on the world wide webby internet thingy, I have no absolutely no association with these people whatsoever, commercially, or, as a customer, if it blows your machine up, don't blame me.......

This is what it looks like when you view your installation, it's quite in depth, you can play around with the settings to your heart's content.
