I've looked at some threads about using computer fans for ventilation. There are several schools of thought about them, noise, speed, airflow, etc.
1 - They use less energy, the 120mm fan only draws about 0.5 amp
2 - They are very quiet compared to a Fantastic fan
3 - They flow less air than a regular vent with the larger 14" fan
4 - They would cost less than a $140 regular fan ($40 for a vent & $30 for two fans = $70)
Here's my question to folks who have used them, or a more conventional type of fan, is this a good option for running ventilation on a teardrop? I don't mind paying the $140 for a "store bought" type, but after reading about the noise, people trying to slow them down due to airflow & other things, is the computer fan installation really a good alternative? Are they designed to run in a "flat" position and last long enough, or do they have to run in a vertical position?
We will have AC for hot weather, but I'm not camping here in Tucson in the summer (have to be nuts to do that & I'm not quite there yet). At higher altitudes and farther north, will this type of setup work well enough? I'm thinking for the same $140 I can have a metal side vent, two computer fans, a metal roof vent (durability) and everything I need to make it work.
