Nvidia Drivers and Vista Aero Temperature

Hi everyone. I have just put Vista on my Dell E1705. I have noticed with the Microsoft provided drivers my 7900GSX runs about 53C, when I used to get 45C in XP with the Nvidia drivers. These are both with the fans on full for the GPU. This is acceptable since the video card is doing some work to display Aero. But I noticed that once I put the Nvidia drivers in Vista the temperature shot to 60C with the fans on full. So I checked EVEREST and realized that with the Nvidia drivers the video card is running the core and memory at full speed. And temperature monitoring is disabled with the Nvidia vista drivers. Luckily I8kfangui still sees it. I also noticed the temperature go down when I unplugged it from AC power. I set the laptop to stay in high performance mode with aero enabled still even when unplugged but noticed that the core and memory speeds went back down to 2D mode (using EVEREST). It went from 600/800 down to 200/300. The temps also went back down to 53C. If they could some how fix their driver to do this when plugged in it would be great. Anyone else experience this problem? I am using the 101.41 beta drivers from www.laptopvideo2go.com

Hi,

I have exactly the same issue. I have deactivated Aero, the problem is still here.

Have you found a solution ?

No I have not. But I just installed the 158.18 drivers and initially the temperatures were lower (~53C), then they went high again(60C). Right now it is again low but that may be becuase right now it is connected to my laptop cooler. Just got the new version of Everest 4 and it sees the video card temps again. I also noticed in order for games to work properly I have to uninstall the old drivers, restart, uninstall the microsoft nvidia WDDM driver then scan for hardware changes again so it reinstalls the WDDM and then you can install new Nvidia drivers. Thats what got rid of the slow fps and flickering in games for me at least. Hope this helps.

I have installed I8kfanGUI (which manage the fans according to the temperature). It behaves much better.

However I would like to have this kind of management done natively...
