I have a 5v usb fan and I want to reduce the speed. how would I do it?
the fans on my laptop cooler is too loud.
thanks
Thanks guys.
but I solved this awhile ago, I reduces the speed by soldering 4 150ohm resistors together. Not sure how much that droped the voltage to.
They are 5v laptop cooler fans.
I tried puttibg some grease on the fans, and it didn't help with the noise, so I felt I needed to reduce the voltage.
