about the eletric fans...
 

well, im getting sick of the fan clutch slipping, so im getting a permacool i have a few questions...

1. could i use a 14in fan and still be fine? (16 is currently out of stock)
2. does it come with everything i need to set it up? is it auto or do u have to switch it on yourself?
3. would it be better to do this myself or should i have a mechanic do it?

TIA
