Topic: Modded fan noise

[Bashy]

HI folks

When its cold sub zero, or freezing fog, my after market fan starts to make a noise, i have a feeling its spinning too fast and perhaps getting icing on the blades, pretty much the same way props do, what do you think? Its fine any other time....

I have a small power supply in the garage for my 2 meter Ham rig that I have out there. It makes a lot of noise when it first starts up, but it settles down after a few minutes. I think that the lubricants are not working well due to the cold.

The "official" Davis fan in my ISS makes a racket too. The 2nd fan in my converted Temp/Hum station is better but sometimes makes noise.

Since it is out in the yard and I normally can't hear it, I figure that as long as it "works", I am not going to worry about it.

Mine make kind of a rattling noise, for your fan is this a "whine" rather than a random clattering noise?

Hi Greg, I have a nodded led light that tells me how the fan is running too, and when it's making the noise it's also slowing down, I too have a pc psu running the fan and one of the fans in that makes a rumbling whine too must just be below the operating temperature for them....
