Question cooler master Hyper LED turbo red cpu cooler question

[kodak9339]

So I have the Mastercooler 212 hyper evo in red, upon inspection of the male pins that connect to the double fans. I noticed that one of the cords has a 3 pin whereas the other has 4. Is this normal?

Yes,that so it can force both fans to run at same speed.
