Honestly I find people claiming something is "inaudible" or "not audible" on the internet extremely dubious, because every time I buy some cooler that people claim is "inaudible", I find it very audible. Either I have good ears, or people have very bad ears or loud environments. I assume in many of these cases people simply live in loud cities and have lost any feeling for what the word quiet means and regard PC fans whirling around at 20-25 dBA as quiet.

And in any case, with air cooling and components that aren't bottom-of-the-barrel, the quiet part ceases as soon as load is applied anyway. But that's what I'm here for, so a PC that's only quiet as long as I don't use it - pointless.
