We tested temperatures, cooling and noise with the W550s at idle and under full load using AIDA Stability test and wPrime. These test simulate how the W550s would respond to light workloads like web surfing and word editing and then under high demand workloads. The W550s was setup using default settings for power use. Our room temperature was 76F for all the tests that we did. All temperatures shown are in Fahrenheit.


The two sets of numbers at the top left show what temperatures we measured at the cooling vents. We saw the highest overall temperatures here, but this is as expected. The working surface of the W550s did reach 83F at high loads so it was a little bit warm, but generally the W550s remained relatively cool and was pleasant to work with. The cooling vents output does get somewhat warm under high loads, but is about average for some of the laptops we have used.

Now we are looking at temperatures on the bottom of the W550s. Overall, it does not get that warm, except for the left rear corner. You might want to keep this in mind if you would be using the W550s on your lap. It was comfortable to us, but for extended periods of use, you might want to have something to set the W550s on for your comfort.

This graph summarizes the idle temperatures and max load temperatures. The W550s has a very comfortable cooling range compared to the W540 which can get rather warm. The W540 has a CPU with double the core count vs the W550s so it does not draw as much power which helps to keep the W550s cool.

Sound output measured sitting in our chair and the meter placed at head level. The W550s really hardly makes any noise, even under full workloads. We found ambient room noise to be about equal to the sound output of the W550s and it was just becoming noticeable when we had the fans set to 100% and then under full load.

The W540 does make a little more noise, but overall both these laptops run nice and quiet with the W550s take the lead as a low noise laptop.

William Harmon started working with computers back in 2005 and began overclocking all kinds of different setups. My focus back then and even now is extreme cooling using Single Stage Phase units, Cascades and Liquid Nitrogen. During this time I was also in several competitions that GIGABYTE had sponsored, GOOC 2009 and 2010. Using technics in overclocking and cooling that I have learned over the years I started building high speed workstations and servers for clients who needed higher performing systems. Many of these systems are used in high frequency trader companies and work stations used in all kinds of professions. At TweakTown, I provide and develop accurate test and benchmark methods for servers and other equipment to help make purchasing decisions easier.
