YIKES! You should definately replace the fan on your GPU!
That said, I'm not sure what temps are ok for AMD cpus. It is a good idea to have fans pointing in near your hardware, and have the exaust fans(pointing out) further away from your hardware. Closer is better, but if you have limited places to put fans, keep the intake close to the hardware. That way your hardware gets cool air. Make sure you have an even amount of airflow going in as you do going out(within reason). If you do not it puts strain on the fans and will reduce their lifespan. Remember your
PSU will likely have a fan exausting too.
