Will I be able to control fan speed with my BIOS or any other type of software that controls fan speed with this connector? http://www.newegg.com/Product/Product.aspx?Item=N82E16812423164&ignorebbr=1 Its powered by Molex but I want to be able to control fan speed via BIOS or software. Im using these fans http://www.newegg.com/Product/Product.aspx?item=N82E16835103052

Thanks

Go to http://www.almico.com/sfdownload.php

Download tbhe SpeedFan program. Install it, and select the tab where the fan controls are. On that page setup a cooling curve that follows the following:

40% at 45°C
50% at 60°C
65% at 70°C
70% at 75°C
80% at 80°C
100% at 85°C

Help on usingf this program to control your fan speeds can be found at http://www.almico.com/speedfan.php

I dont want PWM control, but I dont want to have no control either. What if I use this for my Fan control http://www.newegg.com/Product/Product.aspx?Item=N82E16817182348&ignorebbr=1 I have 4 fans that I will hook to it I will hook a 80 mm fan to the one fan control on the Rosewill controller. I will hook the other 3 fans to the second fan controller on the Rosewill fan controller. I will use either this http://www.newegg.com/Product/Product.aspx?Item=N82E16812423162&ignorebbr=1 connector or this connector http://www.newegg.com/Product/Product.aspx?Item=N82E16812423164&ignorebbr=1 One of them has a Molex option which would be the better connector you think?

If I remember right, in the original post, you linked a 3 way splitter. Now in the above post you link to a front panel 2 fan controller. If you are going to ret controlling 4 to 6 fans from a 2 fan controller you may well end up drawing too much power for the controller.

I have never used a controller line that. It is so much easier to install a software fan controller based on the system temps. Software never forgets to turn up the fans. It also never forgets to turn them back down as things cool down.

On the other hand, we can let a human do it... LOL

OK How bout this. Install the fan controller here is a link for it http://www.newegg.com/Product/Product.aspx?Item=N82E16817182348&ignorebbr=1&cm_re=fan_controller-_-17-182-348-_-Product plug it into main power http://i1024.photobucket.com/albums/y301/jason_hash1/Fan%20COntrol_zpstveupdak.png as seen in picture. Then use this connector http://www.newegg.com/Product/Product.aspx?Item=N82E16812423164&ignorebbr=1 and plug it into the fan wire here as seen in photo http://i1024.photobucket.com/albums/y301/jason_hash1/Fan_zpsnztmee6y.png Would that provide manual control and give a signal? The controller would provide the power and the power supply and limiter would be betwenn the fans and the power they receive??????????????
