It is all about the parts you use to put it together. It is not allways a good thing that the fans are quiet. You have to know how much air it moves per second. There are fans that put out something like 30 cubic feet per minute and run at the same volume as a church mouse pissing on cotton. Thought that would be a high end expencive model, so like I have said before, it is all about the parts and price. You said that there is little to nu heat comming from the computer. That could be a bad thing. All computers make heat, and depending on what components you have they make a certin ammount of heat. No matter if it is brand new, a year old, or a decade old. So the fact that the computer is not putting out any heat would lead me to believe that either a fan is out, not working properly or you have water cooling in some form or fassion. Just my take on it.
