Power, Temperature, And Noise Benchmarks
With a well-defined idea how each of these nettops performs, it's also important to consider power use and noise. Especially when it comes to enclosures without much airflow, cooling is a particular challenge that we need to evaluate.
We've finally found something that the ASRock CoreHT 252B struggles with in comparison to the other three competitors. The results are expected given a desktop-class processor. However, all of the machine's components still use less than 60 W with a full GPU and CPU load applied, so that power number hardly seems extreme.
The rest of these systems just sip power. It’s interesting that Arctic’s Atom D525/Mobility Radeon HD 5450 combo is more power hungry than the E-350- and Core i3-430UM-based machines.
The temperatures are so close that the differences are barely worth mentioning. Arctic's MC001-BD does exceptionally well when you consider that it’s passively cooled.
Although Arctic is the shoo-in given its passive cooling system, the other models hardly generate enough noise to notice. We wouldn’t mind having any of these systems in close proximity on our desks.
