Or the other way around. What RadLinker reports is the actual clock frequency. It is a popular practice to double the figure just because there is DDR technology in there, but it is wrong to do so since double datarate technology does not affect the actual clock frequency.
I don't know about the fan speed. The fans are larger on these cards compared to older ones so perhaps they don't need to rotate so fast. The cards getting quite hot is normal, as long as no real problems arise like crashes or graphical glitches. Perhaps the fan speed could even be regulated by temperature on these cards, but I haven't actually used one yet. Wich pains me greatly at the moment.
