can a 3 pin fan header work with a 4 pin?

intel_pwm_fan1.jpg


like that, will a 3 pin connector fit and work properly?
 
All you have to do is plug in your fan where it fits(so to speak)....

In the picture it is the top 3 pins....you see the little tab thingy..... that makes sure your fan(3 or 4 pin) goes in the right spot....

Hope this helps...

EDIT
As such u will loose that pulse thingamajiger modulation thingydo(thats what the 4th pin is for...its a Intel noise reduction thingy....).....but its not needed as the fan does not have it....

i believe it should, i had a few 2 pin fan header working in 3 pin jacks and they all worked well without problems

no i was looking into getting the Intel D975XBX (intel flagship mobo) and they had lots of 4 pin fan headers. so in th epic it seems as if a 3 pin would fit

I still prefer using knob-based (with a pot) fan controller; it's more traditional and gives you accurate adjustment.

Using your modding imagination or sacrifice a 5.25"/3.5" bay,

hmm i wanted to get a P180 and add a 120mm fan in the front, sacraficing 3 5.25" bays, but to increase airflow so the fan controler couldnt fit.....mmmm
