I should mention i've been running games fine too like metro2033 and tf2
That's not long enough for a system stability test using Prime95. You need to run all the FFT's for prime to be of any use. When you open Prime95 tick the *Custom* bubble. Make sure the number of torture test threads to run is proper. (4,6 or 8 core's depending on CPU). Leave the min and max FFT size at default. Leave the Run FFTs in-place box un-ticked.
Now you need to set the memory usage. When Prime95 is running you want about 95% of system memory used(this included both OS/background apps and Prime95). So if your PC use's 2 gig's out of 8 at idle you want to set prime to use 5.5(ish) gig's of RAM for a total usage of 7.5gigs out of 8. Just tossed those number's out as an example, adjust them as per your RAM usage.
Then you can select how long to run each FFT. You want to leave this at 10-15 min.
Now you leave Prime running until it has ran all FFT's tests, how long will depend on your CPU/RAM speed's. I know my i5 2500k @ 4.7Ghz and RAM @ 1866 CAS 8 it take's around 17-18 hours and on my 955BE @ 4.0 RAM at 1600 CAS 8 and 2800CPU/NB it take's about 21 hours to run all FFTS.
This is the best way to use prime for a Stability test. If you are looking for a faster test you might try Linpack.
Another method to test your PC's thermal's is to run Intel Burn Test(with lots of RAM usage) and then while its running load up FurMark. This will put your CPU, RAM and GPU under stress all at the same time, let it run for like 10-15 min to see what your temps hit. This is how I have tested stability and Thermal performance for a while. Hope this helps you some.
