I noticed my 300 will get hot pretty quick if you get stopped in the woods. I wanted the oem fan but it won't fit with my moose radiator cages. I've read about using a fan from a pc, I went one better. They junked out a Dell server at work. I got the fans. Each one kicks butt, way too noisy for a home pc butt moves a lot of air. The current draw is 1.25 amps. I mounted it to the moose cage, top right side. I used a drill bit with some tape for a stop and drilled 3 holes to mount the fan, used some self threading screws and red locktite. The cage is 5mm thick and the screws don't come out the back side toward the radiator. The back side of the fan needed two of the mounting ears trimmed off to clear the tank. No matter they aren't used. I fused it and switched the ground side, if it would short out only thing that can happen is the fan will come on. I just mounted a switch up by the speedometer. Raced last weekend, 90 plus degrees and tight slow woods. The fan worked great, it does make my leg hot. Like being back on my street bike. Used a bunch of free stuff and so far so good. It's been pressure washed 3 times and still works. I have a few spares anyway. I have some pics if anyone would like to see it.
