They do a good job of keeping it cool.

terrible! permanently attached cables destroy ANY effort for a neat wiring job

The included power source seems to supply the extra power required, but mine are doing a great job below the high

Room temperature is usually around 73, so it does a great job keeping things almost at room temp, just on Low power!UPDATE

I'm sure I could have done a better job of cable management, and may do that in future, however they run nice and quiet at low and medium speeds
