Summary0000192: no video card temp and only 2 out of 4 fan control
DescriptionI have a brand new Chaintech VNF4 (nvidia nforce4) and a Leadtek WinFast PX6600 GT TDH (nVidia pcie 6600gt). The MB has four fan connectors but speedfan only detects three. Of those three it only get's RPM data from two and only controls those two. The temps from my video card are not detected either.

I'm new to speedfan and don't know much about tweaking it. Is there something simple I have not done?

Not every fan header must be connected to a sensor. If you can't read RPMs, try to enter CONFIG / ADVANCED and select a higher FAN DIVISOR. 4 or 8 should do the trick.
I'm working on the video card.

Thank you for looking into this. Unfortunately, changing the divider and or multiplier of the fan doesn't help. However, I also tried to monitor the fan with MBM5 and it couldn't see the fan either. I swapped my fans around to eliminate it as a posibility. My guess is my motherboard doesn't have the third fan sensor of the IT8712F conected to anything and just 2 additional fan power coneccters on the board. So this is no fault of speedfan.

Thanks again, and I'm really looking forward to the support of pcie.

If SpeedFan could also read the GPU sensors too, that would be great.
I own the same video card model. It has a hardware monitor and its own
hardware monitor tool displays two temperatures (core and ambient).
The fan however has only two wires and the tool does not display a fan speed.

PC Games Hardware reports that there is a modified BIOS for PCIe 6600GT cards
from Aopen. Together with a program called Silentfan, it is supposedly able
to control the fan power according to the core temperature.
That might help, maybe I'll try that.

Never mind the Aopen GPU BIOS and fan control program. The Gainward Expertool program is able to dynamically (or statically) control the fan speed of the PX6600GT, with the card's stock BIOS. So there at least is one relatively easy way for owners of this card to control the fan speed (and noise). The tool also displays the temperature, but only on the setting dialog (not when minimized) and it does not record the temperature for graphing. Only a slight disadvantage: one more tray icon.

Since Speedfan 4.23, both GPU temperatures are detected all right.
'local' is the 'ambient' card temperature, 'remote' is the GPU core temperature.
A pity that the card has no memory temperature sensor, as the memory chips can become quite hot (not a SpeedFan issue, of course).

thrax2000, about your mainboard, I guess that's not SF's fault. The manufacturers don't fully develop their mainboard's capabilities. For example: My NF4 mainboard has five fan connectors. SpeedFan detects two sensor chips with a total of six RPM sensors, but only three of these (the ones connected to the IT8712F chip) ever read non-zero RPM values.
SpeedFan detects eight fan speed controllers, among which are three on the
IT8712F. And only two of these actually have any effect.
