    Yep, that's right about where I'd expect it to perform (a little tweaking would likely get it into under 20m range). Further reinforces the position that sheer core/thread count is strongest weighting factor for CPU 3D rendering (as other tests previously mentioned here were demonstrating as well).

    With a little tweaking i got it to slightly under 18 mins. Could certainly go below that but i am not too comfortable overclocking it to 4Ghz.

    I am also using the Noctua NH-U14S, but with two fans.
    Its working pretty well with PBO enabled.

    I think I'm going to add a 2nd fan to mine as well.
