NZXT’s new Cyro E40 cooling pad, announced only a few days ago, fits across 15″ notebooks and features movable fans and a steel mesh design. NZXT states that the fans allow users to pinpoint laptop hotspots in order to cool the notebook down more effectively. If your notebook gets suspiciously hot while you’re gaming or watching movies, keep reading to find out if the Cyro E40 can help.

The NZXT Cyro E40 has one purpose and one purpose only, to cool your notebook down while you’re stressing the processor. Gamers in particular will find notebook cooling pads to be handy, if not essential. Unlike most entry-level coolers on the market that you’d find at best buy or Walmart, though, the Cyro E40 has two unique features: it has movable fans and a steel mesh design. The former allows users to cool their notebook down more effectively by moving the fans around the processor or hot spots, and the latter allows for notebooks to sit on a cool, steel surface and for better air circulation. You can take the cooler apart easily to get to the fans (i.e. a screwdriver isn’t necessary).

It’s also important to note that NZXT assures that even though the fans stick to the steel surface of the cooler with magnets, they are low-powered and will not harm your hard drive or any other part of your PC. The Cyro E40’s product page states that it is “engineered to be safe around any piece of technology.” We can confirm that we didn’t have any technical difficulties or hard drive failures during our test.

The Test

To see if the new Cyro E40 notebook cooler does what it’s supposed to do, we took temperature readings with our IR temperature gun (the Fluke 561) while connected to the internet, and while playing Portal 2 and a letting a movie run in the background. In other words, we tried to stress the laptop as much as possible before taking the first set of temperature readings. We took readings both before using the Cyro E40 and after using it with our test notebook, the Lenovo IdeaPad Y570. We let the cooler run for 30 minutes before taking the second set of readings.

Temperatures before using the Cyro E40:

After seeing that the two hotspots on the bottom of the notebook were in the center and the top-right, we stuck the fans in both of those spots. 

Temperatures after using the Cyro E40:

As you can see, in most cases, the cooler managed to do a decent job with cooling our notebook down. There was even a five degree difference on the bottom-right corner of the notebook (in the second picture). Although the notebook was still a little too hot for comfort around the CPU at 107 degrees Fahrenheit, the Cyro E40 still managed to bring the notebook down by four degrees in that hotspot after 30 minutes of cooling time. If we weren’t playing a movie as well as a game while testing, the notebook wouldn’t have reached such high temperatures. Another thing to keep in mind is that the cooler does have a ventilated steel design, so it’ll be much more lap-friendly than just the notebook would be by itself.

NZXT Cyro E40 technical specifications:

  • Fits up to 15-inch notebooks
  • Most of product made from steel mesh; rest made of plastic and some rubber
  • Removable mesh cover as well as two movable 2×80 mm fans
  • Plug-and-play compatible (USB)

  • Dimensions: 2.36 x 16.53 x 11.81 inches

If you don’t want to spend that much on a notebook cooler, the NZXT Cyro E40 is a good option to go with. We cooled our notebook down by as much as five degrees and most places of the notebook were cooled to some degree during our test. It’s also nice that for only $28, you can buy a steel mesh cooler that has movable fans – features most entry-level cooling pads don’t have. Although the Cyro E40 doesn’t work miracles because it’s not liquid cooling based or over $100, it will definitely help bring those tragically high temperatures back down to a safe level.
