Noise and Cooling

By packing the entire video card into a shorter design there is a good chance that they have added to the heat output on the HD6670, to add to that the smaller heatsink size gives them less potential cooling power. Because of that when it came to checking out the cards cooling performance and noise I was a little concerned. As it turns out my concerns were not needed, the HD 6670 LP stays reasonably cool even when being put under load. With good cooling in a small package there is always a chance that they increased the RPM of the fan on the heatsink to help with its performance but I was impressed with the noise output of the card as a whole. In fact I had to turn off the other fans on our test bench to even hear it at all.
