Right temps for a Thermaltake Contac?

I've just installed a Thermaltake Contac for my Phenom 965 (C3 stepping/125 w) and I've set it up so the exhaust fan is just under and blowing air up towards the top exhaust fan in my Antec Two Hundred. Idle temps are 40 degrees and load is under 50 (after a bit of light testing with Fear 2); I've spread the thermal paste into a thin layer with a bit of card. Are these about right?

Update: I've fiddled with the BIOS and made sure Cool n Quiet is set to Auto and power management in 7 is set to balanced with the HDD shutoff option disabled and link state power management disabled. Temps have now dropped to just over 35 degrees and the included fan is spinning at 1300RPM.
