Report Correct value provided for use on a table

It has been 3 or 4 years that I have this fan. At first I had bought to put it on my lap while working in bed impossible for this use because the 3 fans are actually not protected under (open space). Not very safe and all ... So he stayed in the closet. Now I have an old Acer laptop that can not be moved (because of connections required): he spent his time off, and I realized that the internal fan was not working. So I use this triple fan on the computer but on the office table permanently. And there is good cooling. By cons, you must love this side blue lights! Similarly, the USB jack spring enormously and can damage the connection if the button too hard inadvertently. But given that the effective and safe use fans on the knees are more around 40 euros for the use I made (especially internet, external CD drive, no resource users games), it cools sufficiently the 'computer (a 15 "EP on this tablet) so that I did not need to buy something else: the computer never goes out So okay but well see what use you want to do ....
