I actually use a fanless video card. The Palit Geforce GTX 10050Ti. I wanted my PC as silent as possible as well. The Palit video card works great for all 2D stuff (web browser, video, youtube, Word, Excel, etc., etc.). It works well for mild 3D gaming also. However, if you are running some of the more aggressive 3D games, you absolutely need a fan or multiple fans on the video card. This card just gets too hot on aggressive 3D gaming.
Teradak used to sell computer linear power supplies in separate cases on ebay, but it looks like they have stopped. You still want some sort of fan that will circulate air within the computer case itself.
