I'm thinking about buying a new computer. The problem that i have with the "usual" computers is: They are too noisy. I'm sitting in a really calm room and the sound of the fans attracts my attention. My current computer is a Shuttle SN 95G5 with a passive cooled ATI 9600 graphic card inside a silent box. This is a quite good solution. But for the next computer, why not try a model without any fans at all? I've found this offer. E.g., Midi Tower, Intel Core 2 Duo E6750, 2GB RAM, 500GB Harddisk and GeForce 8600GT graphic card for 2290 EUR (without OS). Not a single fan inside and the harddisk is enclosed in a noise protection case. Ok, it is not really cheap, but life is not supposed to be cheap. The question is: Can one up-to-date computer really be completely passive cooled via heat pipe? What is your experience?
