AC Case Fans - CNCzone.com-The Largest Machinist Community on the net!

I am working on ideas for case fans to keep my drivers & power supply happy.
I like the idea of using 240V AC fans straight off the mains feed, see diagram..
does anyone think that hooking a few fans onto the main input just before the power supply will cause any problems, spikes etc.. I am hoping the power supply will 'clean' and smooth the power as it converts over to DC?

I don't really want to have a transformer of any kind in the case just for fans, so if I use DC fans I guess I would have a second adapted mains input to the case ( not so nice )

Any thoughts would be great..

These types of AC Fans are very quiet, electrical noise wise.
You shouldn't experience any problems with that setup.
