A quote from the article:
>> Noctua NH-C12P CPU cooler Review
Once it was fitted it was practically silent in operation without either the Low Noise Adapter or the Ultra Low Noise Adapter, with those fitted I couldn’t hear the fan on the NH-C12P at all above the other fans in my set up which isn’t at all noisy.
