Cooler Master designed this cooler for gaming laptops and everything from the size to cooling performance really shines. This model offers two 140mm fans which gives you a consistent cooling stream at almost 35 CFM per fan which should be sufficient for just about any gaming laptop and/or demanding software. This one is large enough for a 19 inch laptop and the base includes anti-slip rubber to keep your laptop in place during use.
This laptop cooler also comes with a single mini-USB port, a micro-USB port, and four USB 2.0 ports, so you get a ton of connectivity options. You even get customizable LED lighting which you can match to your laptop and other hardware for a personalized look. Keep in mind that due to the built-in USB hub this model requires a wall outlet, but otherwise it's an excellent option for consideration.
In general, this is a very good laptop cooler, but there are just a few things that keep it from being the very best of the best on the market. Designed with a sturdy aluminum frame, this model has a pair of 120mm fans which offer about 61 CFM of airflow to keep even powerful and demanding laptops nice and frosty. The fans spin at about 1000 RPM with turbo speeds up to 1300 RPM, but it lacks much in the way of fan speed controls.
You only get one extra USB port with this laptop (in addition to the one used for a power connection) which is decent but certainly not as nice as a small USB hub that some other coolers offer. This model is designed to handle laptops up to 17 inches, but anything above 15-inches might hang over the edges of the cooler just a bit.
One of the best things about this laptop cooler is it gives you the unique ability to position the fans however you need them while the lightweight aluminum design offers plenty of ventilation for passive cooling even if the fans aren’t turned on. While the three fans are more than what’s offered by most other models on the market, they aren't especially powerful. Said fans are only 80mm in size with about 15.4 CFM of airflow each, spinning from about 950 RPM to up to 1800 RPM.
This pick measures about 17 inches wide and can support a laptop up to 19 inches in size. This model only has a single extra USB port in addition to the one that connects it to your computer for power so connectivity options are limited. However, a nice extra is the included strap for carrying this cooler and your laptop together by a single handle, effectively making this pick a simple portable laptop case as well.
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.
Although this laptop cooler features a pretty basic design, it actually performs surprisingly well. There's just one fan in this unit but it's the largest you’ll find in a laptop cooler. It measures 330mm in size with airflow reaching up to about 46 CFM. You can also adjust the fan speed between 700 and 1400 RPM. This pick is a little more generous with its connectivity options, including two USB 2.0 ports plus a mini-USB port which gives you a bit more freedom. One issue with this model is that it only supports up to 15 inch laptops, so it is not a good choice if you have a larger computer. Otherwise, for users with smaller laptops it works great.
