Re: AC Fan use in PC??

Other than having to wire a separate external circuit for them, are there any
reasons for not using 120v fans in a PC?? I have a bunch as well as the
tools to mount and wire them. Quiet and powerful relatively speaking.
I've done that to one case long ago: nibbled a hole in the power supply
and ran a zip cord to the internal 120 volt fan.
Like you, I had a selection of fans: quiet vs. louder
but moving much more air.
Any drawbacks via radiated EMF noise??
If anything, I'd suspect that the 60Hz fans have much more metal
so they're better shielded that today's mostly-plastic 12 volt fans.
Remember, the DC fans are turning their magnets on and off
to spin the blades but seem to create no interference.
I wouldn't do it because of the possible hazards and probable
interference with computer operation. However, if you think it's
viable, give it a try. Remember *safety* though. You'll be pumping a
120V line through your box instead of 12V.
AAAAAAAAAAAAAAAAAAAUUUUUUUUUUUUUUUGGGGGGGGGGGHHHHHHHHHHHHHHHHHHHHHH!
I just can't stop screaming enough from that statement.
- there's 120 - 240 volts in the power supply.
Why is /that/ safe?
- mainframe and midi computers used 120v Boxer Fans all over.
I've never seen them 'zapping' anything, mostly because
they used higher quality wiring and connectors than today's 12v fans.
Use a pre-molded fan connector and there are no exposed connections anywhere.
On the other hand, only low voltage fans offer the
yellow tachometer wire to monitor them,
not that you're running any program that'll monitor and report that anyway.
