I use a 15.6 "notebook and it just fits on the Cooler as there is a 19" it should find a place, me remains a mystery.
The volume of the fan is clearly audible, but I personally did not bothersome.
The 1Port USB Hub has worked exactly once, the second connect a device controller seems to have given up the ghost. I would not want me to leave, but I personally have the device but do not buy and a return is too cumbersome.
I was referring to the cooling capacity - and which is, compared to the more expensive Zalman ZM-NC3000U, better for my laptop a lot. The Zalmann is more expensive, but it also handles better, quieter and 3port USB Hub worked so far very reliable. For the cooling capacity was there not as the truth, which is why I bought the coolers reviewed here for private use.
Conclusion: If you can live with a few minor flaws and just want aerate only his laptop for little money, in addition, does not wrong here - you can not just expect too much for your money.
