Can you do a reading with coretemp beta, post the results of both idle and load.
Nice case, the Zalman 9700 has a fan mate fan controller iirc, the 9700NT runs from the m/board (no fan controller)
Being a reasonably new pc I'd expect the temps to be lower than the ones you've stated even on stock cooling, did you mount the cpu? If so what thermal compound (TIM) did you use? have you checked to ensure none of the (stupid) push pins has come undone? (they have a bad habit of doing that)
