Thermal dynamics
To find the UX430UA's idle temperature, we left Windows on the desktop for 30 minutes. The ‘load’ temperature reading comes from running 3DMark Fire Strike.
The UX430UA runs pretty cool when idle, at only 30C, whilst 77C when under heavy load isn't anything to be concerned with either.
Acoustics
There is a slight increase in fan speed under load, but it's only audible in complete silence. If there's any ambient background noise at all you won't notice this notebook's fan.
It says USB 3.1, but the review doesn’t mention if it has thunderbolt 3? The Dell XPS it compares to does have Thunderbolt 3
Nope, no Thunderbolt 3. It would have been in the specs if there was. But you do have a Micro HDMI, USB 3.1 Type C and adapter for full-sized HDMI.
