I made this to adjust the cooler fan (80mm) angle on an old Intel 775 chip set fan. Most (if not all) of the fans on the 775 sit at an odd angle compared to the case, this simple bracket rotates the fan to be square with the case. I just think it looks better, of course this only matters if you have a window in your PC like i do. This may work for other projects that take a 80mm fan but needs the fan rotated just slightly (+14 or -14 degrees). Plus, within the slop of the screw holes you may get more or less degrees of rotation. Working on multiple versions including different styles (labelled as V1 and V2) and I may work on making some for different fan sizes.
