I'm a bit double edged on these products...

If we momentarily disregard the coolers these cards have new PCB designs and some better quality components compared to the reference designs. They also seem to be slightly more power efficient. That's great!

The coolers are perhaps (or rather probably) more efficient than the references for a given feed temperature.
For the 5870 more (read: all) of the heated air is released inside the case, which is bad.
The 5750 has a design looking much like the stock Intel CPU cooler, which isn't really known to be quiet. Some 3rd party tests will have to be carried out to see if it really is more quiet than the reference design.

Overall it's interesting to see the development of VGA coolers' air flow management:
1) Once GPUs became hot enough to require forced cooling there was a simple heatsink and a small fan blowing air in all directions.
2) Then the standard reference design was to take air near the rear plate and push it forward along the card, effectively creating a loop of air passing the heatsink over and over again.
3) Enter third party Arctic Cooling with their "VGA Cooler" series. This was a revolution sucking cool air near the front and pushing the heated air out from the case.
4) Now most middle and higher end cards use that technique with their reference coolers.
5) Non-reference coolers now usually spread the hot air all over, just like it was in the beginning. Very few, if any, non-reference coolers are opted to ventilate all the heated air out from the case.

Cheers
