NZXT Cryo E40 Notebook Cooler Review

We will conduct two tests for the NZXT Cryo E40 notebook cooler: cooling performance and acoustic performance.

To test the cooling performance the notebook cooler will be placed on a hard flat surface which in this case is a desk. An Acer Aspire 5551-A notebook will be placed onto the notebook cooler whilst plugged in to mains power. 15 minute idle temperatures will be recorded on the desktop before proceeding to open Prime95. After running Prime95 for 15 minutes the maximum load temperatures will be recorded. This process will then be repeated without the notebook cooler to ascertain the extra cooling performance the notebook cooler offers. Temperature recordings will be taken from the CPU and GPU to see how the cooling works on the various components in the notebook. Hard drive temperatures tend to be hit and miss on our notebook as it is more reflective of how long a notebook has been on not how well the notebook is cooled. Testing will be done with the fan at 100%. Note we will also record the acoustics of the notebook cooler by using a decibel meter to check the noise output from a distance of 10cm.
