Default How to wire speed control onto my vantec fan?

this is the fan that i have, and its 6k rpm, sounds like a jet plane, but it works well...but it cant run at full speed all the time, i have a speed knob here its the kind that has a 2 wire (one red with black stripe, and one red) so its a 2 pin.

the power to the vantec is a 4 pin same as ide hard drive, but i dont mind soldering or tapping in, where do i put the 2 wires so the knob can control the fan?

here is the fan:

Newegg.com - VANTEC TD8038H 80mm Case Fan - Case Fans


thanks in advance guys

Solder the red from the 2 pin to the yellow on the 4 pin. Solder the black from the 2 pin to any black on the 4 pin. This will create a maximum of 12 volt potential allowing control up to 5700rpm.

Do you not have one of these funky things (similar not exactly what I have which is 2pin to molex);
3 PIN FAN TO 4 PIN MOLEX CONVERTER - Aria Technology

I have a stack of them from my lian li build all the fans had them and thats 6 fans from stock. I could try and take a reasonable pic if you want and attempt to show you the wiring. just going in the shower so do it in a min

Just checked its red on yellow, black on black so I am guessing somethings a dud or your soldering is wrong. Could be over voltaging the fan controller I know that the delta focus flow fans have a tendency of blowing up fan controllers there are only a few that can handle that much current.
