Hello i asked a question and im not sure i asked it the right way for the answer i as looking for..

I have a antec 300 illusion i just got an am going to be building as soon as i can.
The fans are 3 pin and they have speed control connected to them. Im looking at some connectors that are molex to 2 pin from what i read where they are being sold.
I as wondering if them only being 2 pin will effect the fan and me being able to control the fan speed with the built in fan control on each fan.

here is the sale.. im looking at this 1 because its close to me and i want to get started asap.

I hope this helps me understand this time. :D  -Jon

if you remove that little switch that act like a resistor to control the speed do not connect that to the psu or you will blow the fan and maye something else ,

You cant control the fans which are directly plugged to the PSU .

If you use that 3 pin to molex than you cannot control the fan speed .

lts break down this.

the 3 pin has a power, ground and control.
the 2 pin has a power and ground.

without the control pin connected the fan will default to running 100%/.

You can only control the fans which are plugged in the motherboard or else you will need External fan controller .

Yes, it will work without the 3 pin.

Just plug that male molex to PSU's female molex.
