It should be fine derek12 ati tool is very very demanding it will heat up even cards with much better cooling tbh, and is often buggy too with some it was with my x1900xt used to crash instantly. I think its just a case of low end graphics struggling with very demanding software,And laptop cooling is never going to do it justice just hasnt got the space or airflow. Just run some normal games with low to medium settings and see how it preforms, You cant really ask for much more. I have 2 dualcore laptops both with independand graphics ati4530 and they do a decent job if i dont bump everything up stupidly, But i dont really use them for gaming, just internet and occasional movies.
