No, I had not seen that. I went back and read it now. So yes, a truce
Yes a fin-less piece of metal as a heatsink, while is fitting of the definition, does not work very well as one in most cases

What I'm finding strange about these cards, or at least my 5770s, is the voltage they are supplying them with for stable operation. I don't know if when I was going through my overclocks, if it was a coincidence it was stable based on what I was told by someone in another thread who has their 3D voltage for 925MHz at 1.088v since for me low voltage isn't stable now, but I was able to drop my 1.2Vcore down to 1.088 as well and it had been FurMark stable for 20mins... Either way the point is that I think these cards are able to run at a substantially lower voltage than they currently are. I believe they are running 1.1v for 400/1200 right? Which is below 1/2 of their 3D clocks and only .1V more, yet the old 2D clocks (157/300 for my 5770s) is less than 400 yet not 1.0v but .950v

Anyways I found that just by dropping the voltage down from 1.2 to 1.167v (was just a random click really) the load temps dropped a full 3C! That is pretty substantial IMO, for such a little drop in voltage. Point of that rambling is that AMD could've gone a whole number of different routes with the clocks/voltages etc, since they deemed it necessary to go and change the settings for
everyone, which clearly had a negative impact for quite a number of people. I too noticed the increase in temperature, which for me is low 30sC with 157/300 clocks (I don't know if it is .950v or 1v right now though), as it at 400/1200 sits around 42-44C :S Again a seemingly low bump in clocks and voltage for a large jump in temps! My 5770s are only GPU cooled, everything else is convection cooled. Which sucks and I had no intent on getting the CUcore cards, but for $120/ea I couldn't complain

The cooler sucks too, especially at the default voltage, which is why I your pain when it comes to temps.
I'd like to find out what the Mobility HD5870 runs for voltages, since they are quite literally a 5770, except they run at
lower MHz!
