my stock fan with the intel core i7 930 didnt do to good. it idled around 50 degree C and when playing runescape it stayed around 84C. so i bought the CM 212+ and now it idles around 30C OC to 3.0Ghz and max at 53C using prime95. It was using a CM HAF932 case too, so if you was using a small case i say it would be hotter. And the cpu wasnt OC either it was at stock at2.8Ghz.
