Exactly what i needed - quiet and good air movement
I like it quiet in my office, so when i had to prop open the door to the cabinet in which my desktop pc resides, and listen to the cooling and power supply fans all day, i started cogitating. I needed a fan to evacuate warm air out the back of the desk, and wanted it to be as quiet as possible. I knew that bigger would be quieter (for the same cfm), and figured i'd wire in a variable resistor for speed control. When i found this one with the 3-speed switch, and great reviews, it seemed too good to be true.After ordering and being informed it was going to take anywhere from 2-4 weeks to get the fan, i cancelled and purchased one off of a popular online auction site (sorry, outletpc. I received the fan three days later, and was pleased that it had a long power lead and an adapter that allowed it to plug into a spare 4-pin molex extension cable i had lying around. This made my life easier (bonus again), and the fan turns on and off with the pc, just as i wanted. I split a hole in the cabinet back, and fabbed up a mounting plate. I then mounted the fan in the back of the cabinet, and experimented with speeds vs. Internal air temps. It turns out that the lowest speed is adequate for my needs, and the fan is completely inaudible. Now i can close the cabinet door, and not fry the pc's innards.This is exactly what i needed!P.S. Those complaining that the fan is not dbb probably selected the wrong purchasing option.
