ZALMAN Ultra Quiet Notebook Cooler ZM-NC1000
This laptop cooler offers two fans and hundreds of vent holes that keep air moving through your system to maintain low temperatures. Although the fans are rather small, you can adjust the speeds of the fans (between 1100 and 1500 RPM) with an adjustment wheel located near the power button. It runs entirely off power from the laptop it supports, through a USB connection but you do have an extra port to work with. While this model doesn’t have an adjustable height, the ergonomic design is intended to minimize neck and shoulder strain during use. Made of solid yet lightweight aluminum, this cooler is designed for a 15 inch laptop which limits usability somewhat, but it’s a perfect fit for smaller laptops.
