    I have an ASUS TOP GTX 460 with a VID of 1.0v.

    My LCD only has a VGA connector.

    When the GPU temperature gets to about 60C everything on screen becomes slightly blurred. The Fan speed increases and holds the temperature steady at 60C.

    After a few minutes at this temperature, the display gets increasingly blurry (like using a REALLY bad quality vga cable).

    If I manually increase the fan speed the distortion goes away, but the noise is horrible!

    The point is, if the GPU is not getting hotter than 60C, then something on the PCB is getting too hot?

    What component could cause blurriness when hot?

    Thanks

    If the VRM's are getting too hot, they could be causing problems...

    I thought of the VRMs, but would these symptoms present themselves if they get too hot?

    Also, they shouldn't be overheating at stock speeds and voltages and with the GPU temp at 60C?

    Might be time to re-apply some thermal paste and pads

    or maybe its steam... like when you have to turn up the fans in the car to see clearly out the window?
    Sorry couldnt resist

    I could do, but do you know if it would affect the warranty? I've only had the card 6 months.

    Also, this card does has a heatsink on the VRMs, unlike the Palit card.

    The distortion goes away if the fan is at 90% but when the GPU is at 60C and the fan is on auto (at 60%) the blur is there.

    If adjusting the fan, corrects the issue, then something is definitely getting too hot....

    try and see if you can RMA the card, cause that dont sound right at all, Did you OC the card for while and did this just started?

    Yup, It might worth a try.

    If the card is still in warranty better don't mess up with it and try an RMA as the members above advice you to do.

    Have you tried replacing the VGA cable? If the cable or connectors go bad you'll get a blurry picture w/ VGA.
