Need help with cooling

I am a computer guy but I don't build a lot of systems so bear with me. Ok, so I just built my first system in about 6 years. Here are my specs:

Asus P5N-D Motherboard
Intel E8500 Duo Core (not overclocked)
(I ordered the OCZ Vendetta 2 heat sink and it will be here next week)
XFX 9800 GT Video x2 SLI
4gb ram


I am using my old Themaltake XaserV case. One fan each in front, back, and top. Then there is this little door on the side with two more fans blowing in.

When I use the ASUS utility that tells me my temperatures for the processor and my system it says:

CPU - 45C System - 44C (not under load)

Now, I read that the E8500 requires an ambient temp of 38 degrees. So here is my first question, how accurate is that utility? Secondly, are my temps that high where I should be worried? Thirdly, if my Vendetta doesn't help, what else can I do? I can't fit any more fans in my box, just no room. In fact, when the Vendetta comes, I have to take one of the side ones out.

Thanks for any help you can give me, I really appreciate it.

You stay classy!

I thought ambient temperature was the temp inside the box, not the actual room. Am I wrong? Because if it recommends an ambient temp of 38 degrees, that's a room temperature of 100.4 degrees. That's a little warm.

The "Ambient Temp" spec for the processor is the MAXIMUM for the ROOM the computer is in. It is not the internal case temperature. For that matter the "System Temp" shown by the ASUS utility probably also is not the internal case temp - it is more likely to be near mobo components like the North Bridge, which also require some cooling and hence are checked by such utilities. So that temp looks OK, and certainly your CPU temp is OK.

ASUS probe is useless.
