I'm working on building an enclosure for my 3D printers but want to be able to control the internal temperature using quiet PC case fans.
I'm looking at using these fans which use PWM.
For full power they require 12V input.
I've not made an arduino project which uses mains power before (with the exception of a pains power going straight into the arduino itself)
I've tried to do a bit of research and it sounds like it's fairly straight forward to control a PMW fan with an arduino. But I've seen some suggestions that arduino's may not be able to deliver fast enough PMW speeds to allow fans such as this to perform at their full potential (which I will require). Is this true?
If I can properly control these fans with an arduino (Uno is my intention), how would you recommend I power the fans from the mains power? Should I just get a basic computer PSU, or is something else more suitable?
If an arduino natively can't supply the PWM signals required, how would you recommend approaching this challenge?
