I was going to do the same already have two 8 cm computer fans but then thought they would fail the first wash, so I nixed that idea. Have your fans survived washes and road dust or offroad mud??i am actually running a radioshack 12V DC computer fan on my YZ426. You need to rectify the AC current, but once agian, radioshack came in with a rectifier. Total spent was 22 bux on the fan and rectifier. Also, yes, i am still running AC on the bike...
