Really its that loud?
I am curious higher = louder or lower = louder for dBa?
I use a Xigmatek S1283 with stock fan is 20 - 32 dBA and V8 is 17 - 21dBA
Also if you ever run into the issue you can snip the fan control into the next fan as well...all it is a voltage regulator...I usually leave it at auto myself though but I figured you might appreciate the tid bit.
I have done it in the past without any issues...just make sure to cover the wires with electric tape so they never touch.
