Im using multiple 3-pin fans that will connect to this:

What adapter cable do I need to connect the above link to my PWN 4-pin header on motherboard so I can control fan speed in BIOS or using software? Is there a Molex end/4-pin female end cable that exists?

I know Jayz2cents used that block in part of his Skunkworks build and was able to control fan speed

thanks for your help!!


Or would this work better - http://www.phanteks.com/PH-PWHUB.html
 
Solution
Methinks that first one can't be PWM at all. All it has are 3pin outlets and one connector for Molex input for power. PWM needs 4 pins.
Second one looks like better option.
I'm getting 404 error on that link so can't see what you are talking about.
Anyway, you need 4 pin (PWM) fans to be able to control them using PWM feature. No adapter to 3pin fan can give you that.
Power coming from Molex gives only 12v without even fan speed indication let alone PWM features.
