The first passively cooled Coffee Lake NUC or Bean
Canyon small-form-factor mini PC has been introduced this week by Cirrus7
complete with its new redesigned nimbini chassis. Which allows it to run at
least 12° cooler than in Intel’s stock case. Idle temperatures measurements
after running the mini PC for 60 minutes running the Ubuntu 18.04 Desktop was
just 27° C. Cirrus7 explains more about the testing :
Idle temperatures were measured with system booted
to Ubuntu 18.04 Desktop with monitor connected (after 1h).
– Intel NUC8i7BEH: 29-39 °C
– cirrus7 nimbini v2.5: 27 °C
This is a clear win but was to be expected as the
NUC draws very little power (3-5W) idling. The idle temperature with the NUC is
fluctuating because with standard BIOS settings the fan kicks in at 40°C and
stops again at < 30°C. Even when idling the fan starts spinning from time to
time to keep idle temps below 40 °C. Second contest: prime95 torture.
