Fans on Esc's

[BrianG]

0.6A is quite a bit for a small fan and would just take away from whatever current your servos need. And, if you run it at 6v, it will pull even more current. It looks like it moves a lot of air, but that's not necessarily what you want. There is a point where faster and faster airflow provides diminishing returns. A regular fan will do the job just fine. Sometimes it's a matter of just getting any kind of localized airflow. No need for a hurricane!

Something else about fans most people don't think of: They may be high air flow, but have little air pressure. This means that you need some airspace between the fan and the item being cooled for best operation.
