Hi all, ive just bought a nexus fan controller for my pc and would like to be able to install a little lcd screen in one of my spare drive bays (http://www.bipom.com/displays.shtm - that sort of thing) to display things like temperatures and cpu activity. Is this quite easily possible? or would it take a lot of work. Does anyone know of any good modules that could do this and any software or other bits id need? Thanks, Sam

Heres a article on setting up a panel.

Hi, thanks for the info. Also, most of these control panels show RPM of the fans and take 3 pin fan inputs. My fans are 4 pin, even if i use a 4 to 3 pin adapter can the panel read the RPM or do they not carry that info?

4-pin connectors are to power 4-pin fans, also called PWM fans. PWM fans are software controlled. The motherboard controls the PWM fan speed.

The 4 pins diagram is as follows:
1= +12Vcc( usually red wire)
2= GND (usually black wire)
3= SPEED SENSOR (it communicates the current speed of the fan back to the motherboard)(usually white wire)
4= PWM pulse (usually yellow or blue wire)

The computer controls the speed of the fan thru the PWM channel (wire #4). For example, Shuttle barebones have PWM fans for silent use (the fans rotate at minimum speed; when the temperature rises, the motherboard tells the fans to speed up).
Also, some CPU fans require 4-pin connectors (the mainboard controls the speed of the fan).

These fans are backward compatible (they can be used with regular 3-pin and even 2-pin connectors). They just won't be software controlled anymore (some rotate at minimum speed, some at maximum speed, depending on the manifacturer, i believe.)

You will still be able to control the fan speeds with the rheostats. Personally after the first speed readout panel i installed and used for a year or so, i am no longer interested in watching the temps or speeds. I am more interested in how quiet the computer is and have run the computer long enough to know what speed produces what temps.

Yeh, i was thinking i dont really need the display. As long as i can use the controller to turn down the fans when the pc is idle or only being used lightly and then rev up the fans when i want to play a game, that should be enough. Thanks for your advice!
