Tnx Ian, ill find it then, Stefan to get back on the fan controller part if i get a kit and a few parts i can get it together for 60 euro`s, including shipment, if i got the pcb itself i can replicate the kit

, and I could make them upgraded with solidstate relays for 2 fans no problem.
Also picking up the signial from the internal temp sensor as it gives of a voltake and will drop or rice depending on the make of the car, just need to figure out when you want it to trip, and voila 2 fans are running.
Only downside is that its either on or off, but a more cost effective sollution.
So its do able, with some knowledge to make DIY kits that most of us can understand, obviously 60 euro is expensive as its a premade thing, if i can duplicate that its way cheaper, pcb boards and components can be bought in bulk.
