Sunlu S1 Fan Mod - 4010 fan

I wanted to add a temp regulated fan to my sunlu s1 so remixed this model  I've removed the buck convertor as I already had a 24v fan, I used a KSD 9700 normally open 40degrees switch and wired it directly to the power input.  

I had some sizing issues with the temperature switch as mine was the plastic type and not the metal.  Had to open up the hole for it by 1mm.
