Running @ 12V and recorded @ 2.5cm
68 dB
After conversion the results @ 2m are as follows
30 dB
12V testing.
It’s in the upper portion of the table here – doesn’t seem intrusive to me but the numbers don’t lie.
Running @ 7V and recorded @ 2.5cm
59dB
After conversion the results @ 2m are as follows
21 dB
7V testing.
Still up high in the 7V chart. Once again my impression is that the fan is quite quiet but even after repeated testing the SPL meter consistently returns the same result.
Running @ 5V and recorded @ 2.5cm
51dB
After conversion the results @ 2m are as follows
13 dB
5V testing.
As I said in the last review there aren’t many ultra low voltage results here but the Arctic F12 Pro is actually one of the quietest of the bunch at 5V.
