fans blow incredibly cold air
How is the quality of the fan?
The 17.3" Samsung laptop I purhcased was getting pretty hot near the keys so I ordered the largest cooler I could find on Amazon.  Cooler Master has a great reputation, so I figured I'd give this one a shot.The laptop cooler is HUGE. Seriously, they say it's for laptops up to 19" (didn't realize they made them that big) but there is extra room around my 17 incher.  The design is pretty industrial, with the only flourishes being the light which you can thankfully turn off.  There are ugly rubber pieces all around the base, these allow for you to slide in your cables, and actually works well to reduce the clutter.The unit comes with a USB cable, a power adapter, and the stand itself.  The unit has 4 built in USB ports which are pretty awesome at reducing wear on your laptop's ports.  They're 2.0, they have a 3.0 version but it was unavailable from Amazon when I purchased this unit.  The fans are very large and can be snapped out of the unit for cleaning.Performance of the cooler is amazing, the fans blow incredibly cold air towards the laptop, through a metal mesh grill that keeps airflow moving.  My laptop doesn't have large enough vents on the bottom, so they don't really work at cooling it down at all.  Before you buy this you should make sure your laptop has bottom vents that could appreciate the extra airflow, otherwise it's just cooling down the base of your unit without helping your processor or graphics card.I'm giving it 4 stars and keeping it because the build quality is great, and the unit would work with the right laptop.  It also works as a great stand for keeping your screen at a comfortable eye level.  Just double check your unit before ordering, otherwise you might not be getting what you need. (should be sucking in air through the bottom, NOT blowing out- if they blow out, this will have a negative impact on your laptop's cooling system)
