Hydro H100i Fans still make switching sound after FW upgrade.

We're working on an update to resolve the second noise issue you mentioned. It's taken testing on more than 30 different PC configurations to identify it. So stayed tuned on the Corsair forums for updates...

If the fans are not connected to Link then I would look at the fan controller. The fans themselves will not spin up (or down) on their own.

You'd need the Link software to be running for them to be controlled properly via Link. While you're waiting for the update you could run them from the motherboard, or run link and set them to a fixed speed?

It's part of Link, but if the Link software isn't actually running then it won't operate properly.

This thread is somewhat old but I'll make it a try. I Just bought myself a new H100i watercooler and it came with the latest 1.0.4 firmware pre-installed. The H100i makes this constant horrible whining noice which I think only exist on those who have the latest firmware. I've read through several forums for solutions and the only solution that kind of works is:
1) You put some resistance between the Corsair fans and the Corsair Link fan controller eg. make the fan a 7V max instead of 12V.
2) In Corsair Link software set the fans to run att 100%.

Now the whining is not present anymore BUT and this is a big BUT:
1) The maximum speed of the fans is now limited to between 1100 and 1200 RPM = performance mode gone.
2) The sound from the fans is not nice at all. The Corsair fans do sound a lot worse than all other fans that I've been using like Scythe, Noctua, ADDA and Fractal Design, and the Corsair fans is only running at 1100 RPM, should be dead silent in my opinion.

Since it is more than 1 month since Blackbeard wrote that Corsair is working on a solution and nobody has seen any activity regarding the noice issue during this time I believe that there is none. I personally think that there is something wrong with the fans that no firmware in the world can fix. I strengthen this belief even more becasue 2 days ago I posted a question regarding this issue to Corsair and today I got answered that they want me to RMA my H100i. If Corsair would be close to find a solution for the noice issue they would not ask me to RMA it but they did so I guess there is no solution.
