operation : silence !

[toniglandyl]

okay, I'm fed up with the noise that my PC makes, so I'm taking measures to silence it up.

what I have :
Motherboard : Asus M4A79XTD EVO
Processor : AMD Pheno, II x4 965
Graphics card : 8800 GT 512Mb
Case : coolermaster CM 690 II advanced

I've thought of going full watercooling, but the costs are areally a drawback, so I've come up with an air-cooling solution :

CPU cooling : NH-D14
GPU cooling : Zalman VF1000
case cooling : 3x noctua NF-P14 FLX + 2 noctua NF-P12 PWM.

I'm at a bit under 200 euros.

I'm thinking of always letting the case cooling on a slow setting, so I'll never hear them and they will be enough to garantee a good airflow nonetheless.

what are your experiences with trying to get a silent PC on air-cooling ?
is what I'm getting totally overkill for what I need ?
