    No fan sensor on GTX770m?

    I'm pretty sure this isn't a detrimental situation but I'd like to know if any one else has this problem. Using any software either freeware or licensed I get no indication of the fan RPM.... I get no indication that there is a fan working on the graphics card at all, telling me that the sensor is either bad or disconnected. However, I do feel warm air blowing out of the left rear vent (facing screen) whenever I apply a load. I do get the GPU temperature indicated using any software which is all I really need I guess. I'm just wondering if I should be worried about it since it concerns a very important piece of my nearly brand-new expensive computer.

    Thanks in advance,

    Could you download GPUz and open the monitoring tab, scroll down if needed until you see the Fan RPM. There is also the option in all these software types to select which options to monitor, assuming they have a sensor of course.
    To help us help you - please provide as much information about your system and the problem as possible.

    Hello HiVizMan, thanks for the reply. I've downloaded most if not all of the freeware programs trying to get a reading on the GPU fan RPM. I purchased "AIDA64" to get a comprehensive programe for when/if I play at overclocking my machine but still no reading for the GPU fan RPM. There is a heading for it but it only reads 0%. The CPU RPM is listed just above it and that one reads all the time.

    I do feel the warm air exiting the both rear vents when I applyt a load so I know the fan is working. As I stated above I was wondering if this could lead to or is an indication of a more serious problem.
