Q: If I install nVidia's official 52.16 driver from nVidia's website, my graphic card automatically turns off both the LED light and OTES fan. How do I fix this?(Siluro FX5600 Ultra OTES)
A:

This is due to special "quiet technology" included with the 52.16 driver for the FX5600 Ultra OTES; however, if you insist on full OTES fan cooling, please follow these steps:

  1. Instal the Graphic MAX utility that is included in the card's CD-Title.
  2. Restart your system.
  3. Right-click the Windows Desktop and click Properties. Click the Advanced button on the Settings page.
  4. Left-click "GeForce FX 5600 Ultra", and then click Clock Frequencies tab to enter. Click "Settings".
  5. Select "Performance [3D]" and Scroll through the "Core clock frequency" to change the slight Core clocks and click "Test settings". This will turn on the LED light and OTES fan.
  6. Click "Apply" to save the settings.
