SV08 PSU side fans

this is to add active cooling to the PSU pushing the hot air away from the mainboard. This can be used even if the PSU just by mounting it to the side. Suggest using ASA if you do. 
you will need 

2 4010 fans

a Y jst XH2.54-2Pin splitter (you will probably have to make one)

8 14-16mm captive screws with bolts

1 6mm 3m screw

1 8-10mm screw

i uesd these fans but would look for shorter cables or make them shorter. oops.

you can make these changes in your printer.cfg to have the fans use PID. 

!use this as and example and update the pins you fit your needs.
