I have a HTPC which is noisy (CPU fan and PSU). Now I've found a quiet CPU fan - Thermaltake A1889 SilentBoost £23.56 with a claimed 21db, and a quiet PSU - 350W Hiper HPU3S350 £19.93 with a claimed 18db noise level. I know you can get quiter parts but these seem a cheap comprise. So 2 questions:- 1: - Are these figures idle figures (when PC is not busy), or max (when PC is pushed) 2: - Would a mini all in one HTPC be quieter (without going silly expensive), like a base Mentor Barebone - AMD Black Alu MPC-NF2 from http://188.8.131.52/cgi-bin/Light.storefront/en/Catalog/1003 I would rather go the full size PC route as I can upgrade easier. Anyway any suggestions would be greatly appreciated!!
