This Cool ...

Also, I can now dispense cooling by I turn or only a portion of all fans of it.

That the Cooler two USB ports, has two advantages:

1. The USB cable that supplies power, is not firmly connected to the Cooler. That was when the previously used by me coolers differently: If I often took off from this notebook by mistake without first disconnecting the cable, which soon led to damage to the fixed terminal, I at some point also could not fix.

2. The two USB sockets of the new coolers are connected together, so that the free quasi like a USB port on the notebook functions. It goes through the cooler so no USB port on the notebook is lost.

The height adjustment I hardly use.

Overall I am very satisfied with the new Cool.
