Once again the silence of the system block. The previous idea with the non-ventilator BP suffered a fiasco - noisy (disks, thought). I put the SSD, waited until the HDD was asleep, closed the window on the noisy street, bowed under the table, listened... It seemed quiet, but suddenly such a uniform sound of noise, noise, noise and silence. It turns out the cat was sitting in the room, interested in what I was there under the table and went to look. And the shoh-shoh-shoh is she on the laminate topal. A quiet computer, I decided.
