I ordered this as the cable to my side case corsair fan cable is quite short and every time I opened up my rig (which is regularly) it came out the mobo socket, this is a pain for me as I run SLI and the cards obscure the socket so many minutes are then spent fiddling to get it back in. I also wanted to hook up more fans to it.
As it has a number of so called Pwm compatible connectors, I decided to hook up the 2 front of case corsair fans to tidy up cabling as well as the side fan, this was a mistake. It turns out that one cable was faulty and the PWM only works on one of the fans! As soon as I plug those fans back into the mobo then Pwm monitoring started working again on those fans so it has been relegated to just extending the cable to the side fan, clearly this is Overkill for one fan and now i have unwanted cabling inside my case. Grrr!
For the hassle of paying for postage for return I am not going to bother to send this back. Just beware that this cable may not work exactly as advertised.
