I bought a 5830 and after installing it, i realized that it needed two PCI-E power plugs and i had only 1 adapter, so it sat unused in my computer until my adapter comes. While i was waiting, my friend wanted me to burn "Cool Hand Luke" for him, while converting i noticed my CPU temp went to 60° C (which for the AMD Phenom 9850 is the critical point). I havent noticed how hot it ran when i used to convert with my GT 220 in, but after i get my 5830 running, im gonna see how hot it runs...has anyone else seen this happen? - i have this cooling my CPU:
