Ok well I tested my fan with a battery (9v rectangle, incase your wondering) and it spins fine, no dead fan there. So definatly Blown fan fuse then.
If any of you have a dead board with the perfect fan fuse ok and wish to donate it then i would be very pleased and will give it a good home
Alternativly if you could point me in the right direction on where to purchase the correct fuse...
I would assume its safer to solder the fuse in beside the original one with wires rather than try and desolder the original fuse from the board. If any of you guys have had the same problem or have fixed it, then let me learn from your fountain of knowledge
