hi My plan: I'm gonna do some modding on my pc, and the reasons i'm gonna do it is to get my pc mostly quiter. and of course cooler. planning also to try some OC on my CPU. when it comes to overclocking, i know there is a risk by doing it, but i wanna try it anyway. My setup: mobo is gigabyte ga-ma785gt-ud3h Award bios CPU is AMD Phenom II x4 945 95watt case Lancool PC-K56 My shopping list: 3 case fans SilenX iXtrema PRO IXP-74-14 120mm 122m³/h 14dB The CPU Cooler Noctua NH-U9B SE2 CPU 92mm Fan 1600RPM 17,6 dB About the case and mobo: The case got 2 fans that i will replace and the 3rd fan will be placed under the DVD-rom with some strimlers to get more air in to the case. The mobo got 1 cpu fan header and 3 fan headers. What I need help with: I have never done OC before so I need some guidance tru this operation. The conclusion: I hope my plan with the fans and the cpu cooler i've picked out will do my pc more silent and also able to do some OC Any help will be appriciated.
