Is this factory defects or ment to be like this?

post #1 of 5
Thread Starter 
I purchased 50 of these:

http://www.frozencpu.com/products/13374/cab-462/3-pin_Y_Cable_Splitter_-_Black.html?id=dyXGVmLe&mv_pc=601

Please notice how it looks on their picture.

All of my 50 Y cables look like this:



They're all missing 1 cable. I dont understand how and why. Is it supposed to be missing 1 cable? I thought it was factory defects at first, but 50/50 factory defects? I'm puzzled to say the least. Please help me understand.

Pretty sure that's wrong. Even the picture they have on their website shows 3 cables going to each one.


EDIT: On another note the 3rd wire is only for the speed sensor so probably wouldn't matter in terms of actually working right.

That third pin is for the rpm. Since a fan header can only read 1fan speed at a time, that other third pin is not necessary.

That is how a 'Y' splitter is supposed to be. On fan has rpm, ground and power and other only has ground and power. As said above, motherboard header can only read on rpm signal on a header. Feeding two rpm signals can confuse the rpm reading because twice as many pulses as should be are going to header. If pulses are in sync & phase with each other there is no problem, but if they are not the header cannot read them properly.
