Hey guys,

I'm a bit puzzled here and would like to seek help from you experts.

I was using Vista Ultimate when I purchase a GeForce 7900GS 540/700 stock.
RivaTuner shows that it's running 80% fan speed and idle at 41C. (FYI, Vista's AERO activates 3d performance even in idle Windows).

Fast forward till today, I'm using XP due to some licensing issues with Vista. RivaTuner shows 20% fan speed and temp is 50C. Messing around with fan speed from RT doesnt seem to work. When loading 3d graphics, fan speed will increse to 80% automatically. I have totally zero control over the fan speed. Is it a product defect or what?

Then, I increased the speed to 565/730 and ran 3dMark06. I was experiencing laggy screens (like the screen will freeze for a second before continues) throughout the whole benchmark test. The test result was lower than my stock speeds. Any idea why?

FYI, I'm using;
CM Extreme power 430W
Gigabyte GA-8I945PL-G
2GB KVR 533
Galaxy Geforce 7900GS 512MB
Pentium D 3.0 (CPU speed was at stock when the above test was performed. So, I'm pretty sure i got enuff power supplied from PSU)

Pls help..... thx

Fan runs at 80% during 3dmark.
Am already using latest drive from nvidia and RT FR2.0

let's say that it's not receiving enuff juice, how to pump is more oomph to the card? increasing PCI-E voltage from the bios, or pencil-mod or ???
