Dual Temp Fan Controller

[wolffman122]

Hey Guys
Was wondering one if the NZXT Sentry 2, has dual temperature sensors to control two fans independently. What I am trying to do is in a customers home entertainment system they have two cabinets with components. I want to have one controller control each fan and the temperature of each cabinet. If the Sentry 2 does not do that open to suggestions. Also open to how to convert the AC to DC just for the controller and fans?

I went to the website to check it out and it says 5 channels?

AC to DC? Not sure what you are talking about there... THere is a molex power lead on the fan controller that plugs into a molex from the PSU. The fans plug in to headers on the fan controller.

You'll need to buy a DC power brick with maybe 100 watts.

They list a 12VDC one.

It's actually just a small 12 VDC power supply.

Conumdrum, thank you for the idea on the power supply. My only question is I know a molex connector powers the controller, but does the molex just have 12 v on it or do i need to worry about the other wires on the molex to power that controller.

Plug, and play.

Hmm, it has a red, black and yellow. Meaning it might be using 5 VDC also. Also, if your sensor wires aren't long enough you'll have to extend them, which will change the resistance of the sensor, maybe enough so it won't work

Honestly, your planning to run a fan in exhaust at the back of each cabinet? How much airflow do you need? How silent does it have to be? You could just get some nice 140mm or 180mm fans that are very very quiet and they will be on all the time the system is powered up, you'll never hear them from 10 ft (aka the couch).

If you just run the fans, then even a 40 watt mini 12 VDC power supply would be fine.
