My card is at 62 Degrees. Is this classed as normal? I have been playing COD:MW3 for around 2-3 hours. What shouldn't I let this card go over as it only has a heat sink, no fan.
It's fine. Just realize that the Radeon HD 6450 is not considered a gaming card, just a media card. As long as you are happy enough with the performance that you are getting, then that's all that matters.
