Id been looking at doing a 12v conversion to my 65 notch that I'd been struggling with, fingers crossed it's now sorted!!
But just found that Coolair do a made to order 6v dynamo 90mm with 12v insides so you can run the same fan housing etc!!
An easier 12v conversion in my eyes!!
Not cheap though at £499.95
Just thought it may be good to let you all know
Cheers wilf
