I wanted to share my experience with these products for those searching for the answer to the question that I did.
I purchased the Corsair H100i for a i7-4770K Haswell on the Maximus VI Hero motherboard. I set up the H100i as instructed, but I didn't like the Corsair link software or how much noise the fans made. The noise wasn't obnoxious. It was just more than I expected it to make.
So the question I sought an answer to was, can I use the VI Hero CPU fan ports to control the fans of the H100i radiator and uninstall Corsair Link? The short answer is yes.
The long answer...
Corsair has been a bit slow on keeping the Corsair Link software up-to-date with the latest technology. Since the last time I checked (11/5/2013), it has been a month since they’re last update which one of the features listed was “experimental support for Haswell”. In my opinion, they’ve had ample time to work out the experimental part.
I did not like the fan profile management that comes with the Corsair Link. I always felt like it was noisier than is should be. When I would boot, the fans would start full speed until after post and then drop to a lower quieter speed. I still felt that quieter speed was louder than it needed to be. There was a time when I rebooted and the fans went full blast and stayed that way even after rebooting. It was LOUD! Louder than pre-post. It took me a while to figure out that the profile in the Corsair Link software automagically changed to maximum.
With that said, running on the default profile wasn’t very loud and the noise didn’t increase during CPU stress, it was just more than I preferred.
I searched the internets for answers, but I eventually decided to test Hero’s ability to control the fans. The pump that sits on the CPU connects to the CPU_Fan port on the motherboard via a single wire. It simply reports the RPMs of… not sure really. It was always showing about 2,000. I disconnected that from the CPU_Fan. I connected the radiator fan closest to the radiator input/output tubes to the CPU_Fan and the second radiator fan to the CPU_Opt port. I then disconnected the USB header on the pump from the motherboard. I left the SATA power connected. You need that for the pump motor. It no worky for sure if you disconnect that.
I ran the AI Suite III fan profiler and then allowed the motherboard to actively manage the fans. It is much quieter now and the temperature is as lows as it ever was. I uninstalled the Corsair Link software and my system has been running well.
