Hiya, I don't know the measurments but I know it's quiet small! I'm looking for a 2 pin fan that will screw on to the top of my graphics card heat sink. I'm overclocking my Geforce 2 MX 400 w/64MB SDRAM (adding heat sinks on to them as well but got them) w/tv out. Thanks. I am rather skint so if you got one lying around your basement that would be great, send it to me or if you know any good UK shops then please recomend them. I based in UK.
