I did try to get the NH-D14 but it was backordered and was going to take a whole month of waiting to get it.
And since I'm not going to overclock that much I think this one will do the job.
I haven't tested it under load yet because I haven't been able to get Q-Fan working properly on the cooler fans.
Yesterday after writing the post I went and shutdown all fans except for the cooler and I reckon it's the cooler that is producing the most dBa so I think I'm kinda sorted when it comes to fans.
But I'll eventually move the cooler to horizontal and probably get the P14 to act as intake at the front and add a P12 as outtake in the back.
So another question should I just give up on Q-Fan and get the cooler fans working @ 900 rpm all the time with the given adapter?
Seems to me from the testing yesterday that the noise produced when at < 900 and close to 900 is quite the same.
BTW I have no graphics card for now. I'm saving for a 6870.
