4850 temperatures

[Deleted member 24505]

Heres mine with a vf900 on it,it has a modded fan though,and zalman sinks on my vregs and mem.

I am quite happy with these temps,but i am still getting a S1 rev2 next week.

my card died a couple of weeks ago
the replacement is working fine
now im using enzotech's memory ramsinks and mosfets + 120mm fan @ low rpm, just to play safe
i still think the other card didn't die because of cooling issues, since the mosfets sinks were always cool

Those temp's are running cool compared to normal 4800 series

hey guys what temps can these gpus take my cards are cooled with a Duorb on the first card and a Zerotherma GX815 on the second card, in crossfire the GPUs are in the 70'cish range underload but the PCB is hot as hell. This is in a Thermaltake armor case with 120 fans out the ass. Even at default these little bastards are hot and were even hotter with the stock fans.

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.

Im having a bit of problems with my HIS 4850, the temps are fine having a moded bios with better fan speed curves however the fan sometimes stops for a second then spins up again. Very weird, here is a picture to explain the issue more.



Any ideas how to resolve this issue?
