Hi
We have an DLP3010EVM-LC. When the projector is powered on the fans start spinning at full speed to keep the system cool. However it makes a lot of noise.
Can the speed of the fans be controlled by the I2C interface? We like to either:
- Make the fan speed depended on the temperature
- Turn off the build in fans and then either
- Add an external bigger fan blowing at lower RPM to still keep the system, but keep the noise level down.
- Limit the time the LED are turned on, and or, limit their current.
It this possible?
A little background about our systems workflow:
- The projector LEDs are turned on for ~10 to 60 seconds projecting a fixed static pattern.
- The projector LEDs are turned off for ~10 seconds
- Above cycle is repeated at most ~30 to ~60 times. Then the projector LEDs are turned off for long enough to cool completely down.
What are your suggestions?
