Unfortunately, some pump buzz at the higher speeds seems to be quite common on the latest generation of coolers. It is unlikely you'll notice any meaningful cooling difference by running at the slower speed in anything except long duration, full 100% CPU loads. So set it to quiet mode and know you aren't losing anything.

However, the clicking is more concerning. This is usually a mechanical problem or occasionally an issue with power delivery to the pump. Rather than a bad wall socket or ailing PSU which would show their effects all over the system, it is more likely the issue is inside the unit itself. You can be thorough and try a different SATA cable running from a different PSU socket, but the odds are that isn't the issue. Generally, this type of issue gets worse in time and right now you have the maximum flexibility in your return options.

I am not sure if your are US or UK, but usually if you request a replacement and return from Amazon, the new unit will ship out today and then you have 30 days to get the old unit back, zero down time. You can also request an RMA through the Corsair portal back at the bottom of the main page (you need to create an account). They also can do an advance RMA, where they ship you a new unit and you return the old. However, no one else is Amazon and that would almost surely be the fastest, least expensive method of obtaining a replacement. I know it's a pain, but don't wait on this stuff. It will only drive you crazy in the meantime and your options will decrease in time.

You may encounter some issues trying to run AI Suite and CL4 at the same time. Usually these are polling errors and not hardware problems, but is something to be aware of. You can fully exit AI Suite from the task bar icon or set it not to run on start up. It will still retain your fan profiles when the program is not running.
