How to power your Fans from the PSU and monitor them on the Board.

[Maximus Nickus]

Basically you have a connector that plugs into the Board, a high current Delta will damage the Headers, so cut the Red and Black wires leaving the Blue wire on the connector, plug it into the board and your board will monitor your fan.

Next plug the two wires into a PSU connector (red to the yellow third one in the line and black to black one, making sure the wires are not next to each other) to allow it to feed the power, also if need be make a switch to change the Voltage, this way once its secured your PSU will power it but your board will know if it fails and such, great for old boards and such, as you can monitor the fan with MBM5 and if it fails no more fried CPU's!!!!!!:D


Happy oc'ing ya'll!!!!

Thanks for the info, nick_cw. I have a question, why shouldn't the wires be next to each other? AFAIK, the two black wires in a Molex connector are next to the hot wires that they are the return to ground for.

I think:beer: that the four diff connectors have diff voltages and often say your fan will power off the 3rd and fourth ones (or 1st and third) however diff fans use diff voltages so just plug em in (you can't blow it!) see which is right, although most fans use black to black and red to red/yellow.

Also if there further apart and you're a shoddy solderer you have less chance of short-circuiting.

Hope this helps.

But if you wanna use the fans @7v for a tollerable noise, plugging the Delta's red cable to the yellow(+12v) & the black to the red(+5v), you'll lose the fans Rpm signal :(

Maybe so but there are lots of people like me who don't mind the noise and (using 80MM HSF's) can do this to monitor those delta's, I mean if you like to leave it on when u go out (downloading etc) then its a good safety measure.

P.S. The 60MM Delta isn't loud @ all when used with a Thermoengine, however with the WBK 38 its LOUD.

Does anyone know why the Board loses it RPM signal when its @ 7volts? I have a switch on my Delta and as soon as it hits 7V it goes....

[The Doors]

Isn't your Mobo, to get the Rpm signal it wants a ground of 0v, and not +5v, no other ways :(

[Maximus Nickus]

Yeah but loads of us out there run the Delta's @ full volts so this is a worthwhile mod!
