Advice needed: CPU and GFX temps

[michael_saxon]

I've just built the following machine:

Asus M2N32-SLI Deluxe
AMD Athlon 64 X2 4200+ Windsor
Corsair XMS2 2GB DDR2 800 (PC2 6400)
BFG Tech Geforce 7900GTX 512MB
2 x WD Caviar RE 250GB SATA in Raid 0
Samsung 16X DVD Burner
Creative Sound Blaster X-Fi Fatal1ty
PC Power and Cooling 510 SLI-PFC Power Supply

and placed it in a Lian Li PC-S80 case http://www.lian-li.com/Product/Chassis/Middle_Tower/Classical_Silent/M_C_S_PC-S80.htm

First off, this thing is much louder than I'm used to with my last two systems. Secondly, it seems to be running very hot.

My CPU reports a temperature of anywhere from 54C idle to 64C under load. The motherboard reports 57C. Finally, my graphics card hits 86C under load.

I have the PC-S80 stock fans going as well as stock fans on the gfx card and CPU.

My questions:

1) These temperatures seem much too high to me. Am I right? Where about should I be with stock cooling?
2) Do you think I have a problem with case cooling? I really want to be out of the dremel business, so is there something easy I can do to this case to get it to cool down?

I thought that this large PC-S80 case would do the trick, but perhaps not. Any advice is appreciated. Thanks.
