Not all laptops can sit on your lap for too long due to the heat they generate. We review the NZXT Cryo S to see how it keeps your lap, and laptop cool.

To keep those powerful laptops cool, NZXT has released the Cryo LX and most recent the Cryo S. We give the Cryo S a test drive to see how well it does with a work-focused based laptop.

The Cryo S comes packaged in a standard cardboard box and is wrapped in plastic. With the cooler is an AC adapter, USB cable for the two port USB hub on the back, a USB cable that powers the cooler, and instructions.

I would have liked to see a little more packaging protection within the Cryo S box on the top. Aside from the box itself, there is only plastic protecting the top surface of the cooler. A 1/4″ thick piece of foam would easily suffice. Aside from that, the cooler is packaged well, as are the peripherals.

The cooler itself is definitely attractive. Being aluminum and black in color, the black rubber pieces add a nice visual appeal. The fans underneath are also black and fit well with the cooler. On the back is the two port USB hub, power connection, and fan speed dial.

Overall, the Cryo S is a nice looking product. Our 15″ widescreen laptop fits perfectly on the Cryo S. Now that we’ve seen how things look, its time to do some testing.


To test, we used an HP Compaq 6730b business laptop and Lavasys’ Everest. The laptop is powered by an Intel Mobile Core 2 Duo P8400 (2.26GHz), 2GB DDR2 400MHz, 120GB Hard drive, and an Intel 4 Series GPU. To see how the Cryo S dealt with temperature increases, we ran the Everest stability test with the two 120mm fans at full speed.


Stock cooling results


Cryo S cooling results


Idle Stock Motherboard: 40C
CPU: 42C
Idle Load Motherboard: 55C
CPU: 80C
Cryo S Idle Motherboard: 37C
CPU: 39C
Cryo S Load Motherboard: 51C
CPU: 78C


We honestly didn’t think we’d see much of an internal temperature change but we were pleasently surprised. The Cryo S was able to drop the CPU temperature 2C and the motherboard temperature 4C over the stock laptop’s cooling solution. Considering how the Cryo S functions, that is an awesome result. We like that the fan speed is adjustable as we could see some users being picky about the fan noise. Having the option to change the fan speed is definitely a plus. The fans at full speed are noticeable, but not so noticeable that its annoying. The look of the Cryo S is appealing as well. I personally think it looks better than the LX due to it being all black. We liked the option to use an AC adapter in place of the USB cable as battery life would be reduced. Overall, the Cryo S is a solid laptop cooler.

We are trying out a new addition to our scoring system to provide additional feedback beyond a flat score. Please note that the final score isn’t an aggregate average of the new rating system.
  • Performance: 8.5
  • Value: 8.5
