I describe times hir the NC3000U not S. But which are identical from the cooling system and will also only enter into it. I walk straight while I write hir 7GB music files to MP3. My 2 x 2 Ghz CPU works between 75 and 85%. Today my notebook HP 6730s is once again on the couch because I additionally TV watching. After the CA first 10 minutes of converting the music I heard the loud internal fan of the notebook. Quick brought into the next room and the ZM-NC3000U and connected. Previously, I've put a prepared cardboard as a backing on the couch so the NC3000U slightly higher because of the soft couch to the floor surface and so more cold air from the bottom can blow up the notebook. After one minute, the internal notebook fan went down well. At least 50%.
It really is normal that when the NC3000 notebook is nearly surrounded by the soft couch lehene ordendlich gives relief. But for just for the bed the thing is optimal.
It would be nice but if the cooler closed down. Then I would not place the cardboard under it. On the table it does not matter, and also relieves the place well, the internal notebook fan.
