AHhhhhh the saga continues
Well after working diligently to make variable speed fan swiches work, alas it didnt .
The main problem seems to be not enough resistance in the fans to make the switches work correctly. Using just the fan there is Absolutly no fan movement untill you reach about 70% of wide open. from that point there is little to no increase or decrease in speed. So much for 20 bucks a piece slide controls.
OK back to the home depot and I lucked up ( If you can call it that ) they had some 3 speed fan switches that were also slide type. COOL I can live with just 3 speeds. Especaily for a buck 25 each
Well it was not to be either
Hi speed and medium speed are the same and low spped is just barely short of hi speed I could tell a bit of difference by how loud the fans were but not what I was hoping for.
The only way I have determined to make the fans speeds work correctly is to put a 75 watt bulb in parralel with each fan. Tried a lower wattage bulb and it met with basically the same results as no light bulb at all.
I aksed around and a resistor of large enough capasity to do the same thing would generate more heat than the light bulb does so thats out of the question.
So I dont know what to do. Thought of changing the fan circut to 12 volts but then I need a power converter ( which I dont have room for ) and ditch my 3 120 volt fans. While this is the most logical route, the whole purpose of going 120 volts was because there is no power converter in that case.
I am still working on a solution but running out of Ideas.
I couldplace a 12 power converter outside the case or hang light bulbs under my desk to burn off the power ( painted glow in the dark green for that UV effect
)
any other Ideas?
I am open
