H100i fans revving in a cycle - H100i not showing in Corsair link

[zap737]

Hi,

 

I just installed a H100i. The two fans rev up and down in a continuous pulse-like fashion - every 3 seconds or so when connected to the y cable. The Corsair symbol on the pump flashes on and off. When I run Corsair Link, the H100i does not show up even though the dongle is connected to an internal USB header -I have also tried different USB headers.

 

When I plugged both fans directly into a fan header on the motherboard, both fans run fine and at constant rpm.

 

All connections are made.

 

System:

Gigabyte Z87X-UD5H

Intel i7 4770K

Windows 7 Pro 64 bit

Any response from Corsair on this problem would be appreciated.

Also computer would restart by itself when shutdown with H100 cable plugged into USB on motherboard but when I unplugged it, the computer shut down normally.

 

All connections are made as per installation instructions.

I have literally the EXACT same problem. I've returned the first two to where I purchased them. The third is being replaced by Corsair right now. This happens and all three times has shorted out new fans that I have connected so I need to return those too. I really hope this last one solves it because I am about to go crazy! I can't be without a system like this.
