Need help controlling a fan

[lachtanko]

Hey guys already posted here once but that whas solved now i need to know how to control this small fan. The big fan and the small fan are connected into one cable and that cable is connected into the CPU fan pin. So is there eaven a possible way to control the speed of just the small fan ?. 

.

 

Here is the video of the buzzing, if we cant solve it i will have to cut the cable from the small fan...

You need to get them on different cables. How many wires does the small fan have?

if you know how to diassemble the fan and reassemble it, put some lubricant in it

or just drip some non-conductive lubricant in if you can see the shaft from the outside

The big fan cable is too short to be plugged in the CPU fan pin. (wrote psu instead of cpu on the image lol)

It seems like a lubrication issues, or something to do with the fan hitting the housing. If you know how to take it apart, check that there isnt any interference in the fitment, and add some grease to the bearing...

The wires are joined? Is there anything else than a blue wire coming from the small fan? (blue is usually for pwm) If you cant lubricate the fan like others have suggested, you can take the wires from the small fan and put a separate plug on it. If you dont need high rpm you could put it on a 5v supply (USB,molex,sata). Red is usually + and black is -
