Looks like digikey has new stock of 3k. Too bad they didn't get different bins or temps

Nice project you've got going.
I am interested in the pwm controller for your fans. I have a 4 wire 120mm fan exhausting my veg tent right now and I just have the blue wire hooked up to a toggle switch to ground with the black fan ground wire, so it is operating at low speed with the switch on. It is too loud at full speed but I know I could get a lot more cfm out of it if I could pwm the blue wire to ground.
Would I need a circuit like you posted in the schematic above or could I do it more simply?
I am not good at reading schematics for electronic circuits.

Please explain a tad more ...You should use a flux capacitor.
Can I ask what program you use for this? I hand draw and hate it becuse I cannot post my ideas. Beautiful designs!
