something different
Hi
I have some interesting values on a HD 4850:

My MEMIO temps were 5-10 °C higher than the other readings for a while, but since yesterday I have this stupid low temp on it.
Also other interesting thing is that under GPU-Caps Fur rendering the temps would go high fast with MEMIO topping at 70-80°C, and a blank screen after cca. 5 mins.
Under 3DMark, Crysis, or even GPU-Caps running Fur rendering parallel with any other OpenGL demo, it would stay around 40°C GPU core/DISPIO/SHADERCORE and 50°C MEMIO for any length of time.
Another very interesting thing is that when I get high temps under fur rendering I lie down the computer case (which is a tower) the temps suddenly drop dy 20°C. It seems that the heatpipes are not working very well cause they are nearly warm at those high temps, and when I lie down the case they are going warmer.
I am running an Auras Fridge cooler with 2 Arctic Cooling Arctic Fan 12 PWM @ 500rpm
The ramsinks which came with the cooler were enough to cover the VRAMs and the VRMs (??? maybe I misplaced them, I've put two sinks on the two quad-group small chips, see
http://img.techpowerup.org/080710/radeon_3850_naked.jpg) but the thermal adhesives were unable to hold a few of the sinks, so I had to wrap an elastic band around them. I'll replace it with proper ramsinks as soon as I'll have the time.
Also the graphic board is warm but not hot to the touch.
Any explanation to any of the above is appreciated.
Thanks.
