My 8800GT is getting up to 80*C (176*F) (using RIVATUNER) and that seems to be...errrr...not good? I have an HP and the only things modified is the PSU and the GFX card but I am thinking I am needing a fan to keep it cool or a better case but I have a spare PCI slot I am willing to give out.

This one looks right.
Suggestions welcome, opinions wanted.
