hi i have a dm800 and the small fan that was supplied with it is noisy.i have a netbok cooler (5volt usb) and it works great ,the only thing is i want to connect fan to scart so it switches fan off in standby.i have tried connecting fan to scart pin 8 + and pin 4- it does power the fan but spins slowly and led on fan is very dim .if connected to usb it is bright and fast ,any ideas where i am going wrong
