Ok, here is a strange one for you all:
I have a Anidees AI-6 case (very nice) and had a pair of 140mm Corsair AF Quiet Edition fans (3 pin) installed in the front.
Using the cases's inbuilt fan header I had them running straight off my PSUs 4 pin molex (12v).
Even with the speed reducer installed they made an absolute racket and I was not at all impressed with them at all, they drove me mad.
I have now just upgraded to an Intel DZ77RE-75K mobo with all onboard PWM fans.
The strange thing is my hugely noisy fans are now almost completely silent (and yes they are turning) when I connect each up to a PWM (4 pin) header.
Does anyone know what is going on? I thought PWM was supposed to chuck out 12v so they would run at full chat.
Happy but confused, (so long as the temps are ok)
Cheers,
Dave.
