The startup screen is called “About” and it provided system info summary for your reference. Here you can also change the order of boot-up devices and get an overall report on the NUC thermals.
All settings are located in the “Advanced Setup” section. They are very similar to the settings of regular desktop mainboards, so we are only going to single out the most unique ones. The first sub-section worth checking out is “Cooling”. It allows you not only to monitor the current CPU temperature and fan rotation speed, but also set the dependence between these two parameters. Besides standard profiles, you can also fine-tune the fan speed to your liking. So, NUC users will be able to flexibly configure its cooling system to match their usage scenarios and their subjective thermal and acoustic comfort levels.
The “Performance” sub-section where you can usually see options related to CPU overclocking is pretty scarce in Intel NUC’s BIOS. For the processor you can change the number of active processor cores and disable Hyper-Threading technology; for the memory – adjust timings, but not the frequency, but nothing can be adjusted or modified for the graphics core. In other words, overclocking or downclocking are not applicable to NUC systems.
Another interesting sub-section is “Boot”, where you can enable boot-up optimizations.
If you enable all of them, then NUC will start up so quickly, that it will take no longer than 2-3 seconds between pressing the Power button and seeing the OS startup screen.
