Thing is, I sleep in the same room as the computer is in. The noise of the fans is deafening. I actually considered shutting off my computer to get some sleep.
The main thing I want W/C for is not the added cooling but silence. In the final stages of my evil masterplan I want to also silence my HDD (somehow).
The lack of airflow is troubling. What if I mounted my radiator a couple of cm away from the case to allow for at least some airflow? Or does anyone have a better idea how to mount a passive radiator?
