Corsair H115i Corsair Link into Motherboard with only 3.0 USB Ports

Recommended Posts

Hello,

 

I have a Corsair 750D Airflow, Gigabyte Z170x Gaming 7 Motherboard and an H115i CPU cooler.

 

My issue is that the motherboard only has USB 3.0 headers but Corsair Link for the H115i requires a USB 2.0 header. Does anyone know if the Corsair Link will work without issues on a motherboard that only has USB 3.0 headers? I've done a bit of research on this site and have found the following:

 

This thread: http://forum.corsair.com/forums/showthread.php?t=157068&highlight=usb+3.0

 

The thread above suggested a 20-pin 3.0 internal header y splitter cable (12cm) but I then stumbled across another thread: http://forum.corsair.com/forums/showthread.php?p=852472 that mentioned it was a bad idea for the following reasons:

 

DO NOT use these - UNLESS you only use one of the ports at a time. Plugging a device (type 2 or 3) in both ports will mess you up.

1) Both devices will try to signal the host as to type of device connected.

2) Both usb devices will try to ID themselves over the same port (this will really confuse the OS as to WHAT is plugged in.).

3) IF the stupid Y cable split out the two pair of superspeed channels then neither port will work at superspeed (ignoring all the OTHER electrical signaling problems) because superspeed requires BOTH channels to function. And when that failed, the mobo & devices will try to fall back to the original single usb 2 channel with it's pull-up resistor signaling. Where again two devices with interfere with each other.

TOTAL FAIL. !!

 

I then found another thread that mentioned purchasing a Nzxt iu01 USB expansion found here: https://www.nzxt.com/products/iu01-usb-expansion

 

Has anyone had any experience in trying to get the Corsair Link work using the nzxt usb expansion product? Any help or experience would be much appreciated

  1. I have never had an issue when I plug any of my CL hardware into a USB 3.0 port.
  2. I have more CL hardware than most, check my PC specs.
  3. I expect the USB 3.0 to USB 2.0 cable in http://forum.corsair.com/forums/showthread.php?p=842123 will work well.
  4. http://forum.corsair.com/forums/showthread.php?p=852472 is a USB 3.0 Y splitter and totally different to #3 (2 + 2 =22?)
  5. It would be sensible to use #3 to connect a https://www.nzxt.com/products/iu01-usb-expansion to a USB 3.0 port.
  6. I have an NZXT IU01 and have never had an issue and I don't recall any post reporting an issue.
  7. My NZXT IU01 is connected to 2 x Texas Instruments XHCI Controller USB 3.0 ports.
  8. I make suggestions, but rarely get feedback on how well they work.

Hey Red,

 

I looked you up and your opinions are regarded quite highly by several users on these forums. Thanks for your thoughts.

 

Here's the plan based on your feedback.

 

First - I will try the H115i Corsair Link as is and plug it into a USB 3.0 header on my motherboard and report back on Monday ( waiting for the last part of my pc to arrive (GPU). My understanding is that you have plugged the Corsair Link to your H115i into a 3.0 USB HEADER on your motherboard and it worked without any issues correct?

 

Second - If that fails, (Though I doubt it because you are doing the exact same thing without issues, albeit with diff mobo) then I will buy the cable you suggested:

And the NZXT IU01: http://www.amazon.com/gp/product/B0031ESKJA/ref=ox_sc_mini_detail?ie=UTF8&psc=1&smid=ATVPDKIKX0DER

 

I'll report back on Monday on the findings. Also, still open to any others who want to chime in

Just a heads up, I came across too many others who were having issues with the Corsair Link software so I just chose not to install it. I plugged my corsair into the CPU fan header and it's working great. I plugged my Corsair AF 140's (front intake fans) straight into my PSU via this molex from amazon. Everything seems to be running great. My only concern was that I noticed the part of the molex that connects to the fan only has 2 pins while the AF 140s from Corsair have 3 holes (for 3 pins I presume). You think this is an issue?
