To be safe, set the shutdown temp at 80c in the bios if the setting is available. Disable "smartfan", and see if you can stand the increased fan noise. Skip prime95. Run your regular software and games for awhile and see if the system shuts down. If it doesn't, then you're ok. If it reaches the shutdown temp, then you can try some premium thermal paste or switch to a better cooler. Scythe and thermaltake make some pretty good ones. The i7 cpus tend to run warmer; mine idled at 60c and reached 90c under load.
