Default H100i v2 - Periodic Clicking and Pump Noise

So about a week ago, I bought this cooler new from Amazon. Seems to be working excellently, keeping my overclocked CPU at 30 C idle and around 45 C at heavy gaming loads.

However, whenever my pump is in Performance mode, there is a noticeable buzzing noise near the waterblock. Quiet mode seems quiet enough. Performance mode runs at around 2940 RPM and Quiet mode runs at around 1920 RPM. Is this normal?

More importantly, there is a very audible clicking noise coming from the computer every 7 or so seconds. There seems to be a pattern; there is a louder click during the first second of a cycle, followed by a slightly quieter click during the seventh second. It is important to note that these clicking cycles occur whenever I am using a sensor monitoring program, notably Corsair Link 4, AIDA64, and siv64x, even when minimized. In order for the clicking to stop, I need to completely exit the programs. EVGA PrecisionX and ASUS AI Suite III doesn't cause the issue.

The H100i v2 is correctly installed, with it properly mounted onto the motherboard. There doesn't seem to be any vibration. The CPU fan header's automatic voltage control was turned off and supplies a consistent voltage to the cooler. The Corsair Link cable is plugged into a USB 2.0 header and the program seems to work properly (setting fan/pump speeds, LED color, etc.)

The clicking definitely isn't coming from the hard drives, the GPU, the fans, or the PSU. There aren't any cables obstructing the fans. I've tried turning off the PSU's ECO mode and I've made sure that the cables are properly seated. I've also tried turning off the motherboard's OCP/UCP. I've even tried reversing my overclocks and disabling my RAM's XMP profile. The clicking pattern remains.

On the software end, I've tried reinstalling both ASUS AI Suite III and Corsair Link 4. I've also updated my motherboard BIOS and I've made sure to update any other programs I have.

I do have a few other troubleshooting ideas left. First, I'll see if plugging my computer into other wall sockets will do anything. It's currently plugged into a voltage regulator in my room. Also, I'll see if using a hardware sensor monitor in Ubuntu produces the issue.

Does anyone else have any other suggestions as to what I could try? It would be a pain to have to return this cooler and order a replacement. While it does cool my processor quite well, the clicking worries me.
