I want to set up a nozzle fan but I do not want to do any soldering on the board.
I was thinking of hooking it up to where the headers are for the extruder fan and put a SPST switch
inline. I know you do not want to run the fan for the first 2 layers but do I need to control the fan output % ( use a dimmer switch)
why not just run it straight to the 12V screw terminal and add the switch to the ground link.
If you plan to use a 30mm fan, no you don't need PWM.
If you are using a 40mm, PWM can be helpful but isn't neccesary.
the mainboard mod doesn't look too hard. if soldering skill is the only thing holding you back, you should invest in some equipment and learn on some cheap kits then dive in. believe me, with proper prep and the right iron/solder, soldering on a PCB is the easiest soldering there is (as long as its not surface mount stuff, lol).
ive been meaning to get around to that mod myself, this little reminder might push me over the edge. will need to raid my parts bins!
meant to add: if you want to just put a fan on with no interfacing with the printer at all. you can simply power it with a 12 volt (or 5 volt, depending on your fan) wall wart with a switch spliced in the line. that's actually what im still doing, seems to work fine, just have to remember to turn it on.
SMT can be very fun and its actually quite easy with a good iron

This is what I'm doing. I don't want/need any fan directly soldered to my board I think that's not such a good idea. I've got a lot of experience soldering in hard to reach places as I'm a pinball machine collector/restorer and I've found the best thing to use in this situation is the small butane powered soldering irons. You fill the end in seconds with butane and you are good to go with no cords. Easy and cheap. The only part you need to be careful of is to wait till the iron is up to temperature before you begin. It doesn't take much.
