Skylake-U

Passively cooled computing systems are popular amongst consumers worried about noise from fans and their associated maintenance requirements (particularly, for industrial use-cases). Traditionally, fanless high-performance PCs have come with a high price tag. However, with the focus on low-power Core-series CPUs by Intel, we have many vendors targeting this market segment with affordable models. Zotac started a new lineup of passively cooled ultra-compact form factor (UCFF) machines in the C-series back in mid-2014. Initially, the members of the series utilized either Atom-class or -Y series CPUs (with a sub-10W TDP). With Skylake, Zotac has re-engineered the design to accommodate 15W Skylake-U CPUs. Today, we are taking a look at the Zotac ZBOX CI523 nano, a passively-cooled alternative to the Intel Skylake NUC NUC6i3SYH.
