Fan speed contol - System Bios + Molex

[cowboydude99]

Hi all,

My Diablotek case has 4 120mm fans. They all connect using only molex connectors, so there is no fan control.

My system board has a 4 pin header to control the fans, but I cannot connect my fans to the system board.

I could get this: http://www.newegg.com/Product/Product.aspx?Item=N82E16811992005

Or

I was thinking of getting something like this:

Which way would you go?

Any help is appreciated.

Thanks,

That won't help you since it has a single Molex and several small connectors. This would allow you to connect your Molex fans to the MB, if that's all you want to do: http://www.ebay.com/itm/4-Pin-to-3-Pin-Fan-Converter-Cable-Adapter-NEW-/390648660822

But the board would have no tach feedback (3rd wire), so I doubt you'd have any control. And you'd never know the RPM.

That's the trouble with 2 wire fans. No control. You could swap out the fans for 3 or 4 wire fans, or you could look into a fan controller like this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16811999219

Thanks- but I updated my post with the following:

Not sure if these are the same, but I like this look.

Yes, that's basically the same controller with a different face plate, but with the addition of temp probes.
