Zalman 9700 keeps my Q6600 overclocked 10% at 45-50 idle 55-59 full load.
that's with Arctic Silver 5. Don't use the included Zalman paste. I tried the zalman paste on my 360 and it immediately died a day after (Yeah I have the 3rlod error). I used Arctic Silver on my 360 a day later, and it hasn't died on me after HOURS of gameplay. There's VERY good thermal transfer with AC5.
Edit: I'd say 62 Celsius is pushing it.... might wanna underclock it a bit till you get a better cooler
The fan behind it is 120mm. The Zalman sure is big.
