IMO your pushing things too much for the long term health of your system. I suggest picking up a quiet fan from directron.com or something like that and adding one.
You could possibly run it on +12 - +5 = 7V from the power supply by going between the 12 and 5 volt leads to keep it quieter. I'd also be curious about your hdd temperature. Bake a hard drive for a few months and it tends to hurry the RMA requirement.. Still you may be perfectly ok, it just seems chancy to me with a poor ventillation case, with both the fast GPU and PVR card in the long term. 64C isn't really ideal for the CPU either. A very good heat sink with some proper thermal transfer compound may helpa little there.. Good luck.
