Just so you know, 3 wire fans are also able to have their speed controlled by the board's BIOS. Instead of Pulse Width Modulation, it simply uses variable voltage to controll the fan motor's speed.
But if you want a 4 wire fan with PWM to make use of the 4 pin headers and you want quiet, look for low decibel ratings. And remember that larger fans are generally quieter than smaller fans. Did you want a fan recommendation?
Thanks for that. I'm wanting to get two more fans for other the front of the P280 or midcase. What would you recommend? Something that is quiet at low RPM but moves a lot of air through the case?
The reason I mentioned four pin, is because I just assumed that was required as the Z77 has four four-pin chassis inputs.
Thanks very much!
