I am using Sunon HA40101V4-1000U-A99. This is 12V DC fan, but I am using it with 5V DC (according to specification). But I am not able to find values for audible noise, rpm, cpm, current on 5V. Datasheet just provides these values for 12V.
Is there any way how to find it out? Or to deduce it? I would like to get some table with values for specific voltages, how they are influenced (or at least for 5V in my case).
