Thoughts & Testing.
To get up and running is simple, the supplied USB splitter cable plugs into a spare USB socket and then the power cable plugs into the Mini Ninja.
In use, the fans are similar in noise output, to what you might expect from a modern laptop, and are very quiet, with a slight vibration through the aluminium body and a faint whoosh of air through the grille.
I like the design of the Mini Ninja, but I found the angle that it give the keyboard a little bit too steep for my own personal use.
I wasn't keen on the USB adapter as it sticks out about two inches and has very sharp edges, so keep that one away from the kids

.
As I was testing with the Dell Inspiron 6400, I realised that the temps were no different with the Mini Ninja fitted or removed. This is because the Inspiron's air intake is right on the edge of the underside of the case, so there was no air getting to it.
I moved the laptop roughly two inches to the right and we got airflow - not ideal, but fine for testing.
Results are as follows;
There was a drop in temps from
76c to
70.5c under load using
Intel Thermal Analysis Tool.
It was a similar story with idle temps dropping from
46c to
39c.
