[QUOTE="Mew, post: 778130, member: 29012"] To try to keep my HTPC under the TV as quiet as possible I have the fastest passive graphics card I could find (currently an ATI HD5450, I have bought a passive ATI 6570 but it seems to be faulty as it can not go above 1080i 25/30Hz, no 1080p). I have a 92mm case fan (92mm Noctua NF-B9-1600 Vortex) and two 60mm case fans (Acousti AcoustiFan: DustPROOF 60mm)and a quiet PSU (Corsair HX 750) with a large fan. I recently replaced the CPU fan, which was the noisiest component and could be heard (but not enough to distract when watching TV) with a Scythe Shuriken Rev.B. When we next watched a film my wife did not realise the HTPC was already on, such was the difference. The loudest components now are the 2 60mm fans. These are already replacements to those that came with the case and are quieter, so I am not sure I can do much more. The HTPC is now very quiet but I guess I will always strive towards as near silent as possible. It is a compromise between cooling and noise. I guess it helps that it is a dedicated HTPC, not used for anything else so does not need powerful (and hot) graphics cards and CPUs. Mew [/QUOTE]
