Tony Koryban’s mail bag archive today addresses a problem whereby the engineer only needs it to go full blast when the room temperature goes over 40\u00baC. Here’s the question:<\/p>\n
I don’t need it to run at full capacity. I only need it to go full blast when the room temperature goes over 40\u00baC. Maybe I could put in a speed controller to slow the fan down when I don’t need all that air, and a thermal sensor to tell it to speed up again if the room gets hot. Slowing the fan down will definitely make it quieter. Before I do that, is there a way I can calculate the new operating point at reduced fan speed? And how much does the audible noise go down with reduced fan speed?<\/p><\/blockquote>\n
