=== Is it OK for fitlet to run hot? ===
 
Yes. fitlet is very tolerant to high temperatures. The small form factor and passive cooling may result in operation temperature that is higher than the temperature of computers with fans. Users that are not familiar with miniature fanless PCs are often concerned about temperature, but the operation temperature does not have effect on reliability and safety.

Hardware

What kind of RAM can I install in fitlet?

DDR3L-1333 1.35V SODIMM (DDR3L-1066 for fitlet-B). See also tested RAM modules list

Which power supplies can power the fitlet?

fitlet bundle comes with external AC/DC wall power supply, providing unregulated 10–15Vdc input voltage range, 12Vdc nominal. However, any power supply able to supply ~36W from 12Vdc source will be fine.

What are power capabilities of fitlet USB ports?

USB ports VBUS (5V) pair supplied via onboard power switch with current limit set to 2.3A, which means either each USB port capable sourcing up to 1.15A in case two bus powered devices are connected, or sourcing 2.3A in case single bus powered device is connected.

My SSD inside fitlet reports high temperature. Is it normal?

SSDs vary in the power they dissipate. See for example this Tom's Hardware article.

It is recommended to opt for a low power SSD.

fitlet thermal envelope is quite tight due to its small size and fanless operation, so high temperature of an internal heat-dissipating component is to be expected. However, SSDs are very temperature tolerant so the reported temperature is not expected to affect reliability.

Is it OK for fitlet to run hot?

Yes. fitlet is very tolerant to high temperatures. The small form factor and passive cooling may result in operation temperature that is higher than the temperature of computers with fans. Users that are not familiar with miniature fanless PCs are often concerned about temperature, but the operation temperature does not have effect on reliability and safety. Actual temperature varies depending on ambient temperature, ambient airflow, workload and devices - both internal and connected.

Unlike computers with fans that experience degradation in thermal performance over time and may overheat and fail catastrophically in case of fan failure, fitlet thermal performance is uniform and is not subject to aging.

Software

Will fitlet run off-the-shelf, common apps under Windows 7 and Linux? I read in a few places that Linux on Media boxes could leave users very disappointed, even if they get the desktop environ up, because of the few apps that run on SoCs

fitlet is a VERY standard PC in that respect. All Windows and Linux applications should be 100% compatible.

Where are the "gotcha's" with other small systems?
Architecture (mostly ARM) - fitlet is AMD x86.
Non-standard BIOS - fitlet has AMI BIOS with both UEFI and legacy support.
Insufficient RAM - fitlet supports up to 8 gb
Insufficient storage / no SATA - fitlet has mSATA up to 1 TB or so.
Limited graphics, no DirectX / openGL - this was in fact a limitation with fit-PC2, but fitlet has Radeon built-in.

Bottom line - performance might not always be high, but compatibility is perfect.

Does FreeBSD run on fitlet?

FreeBSD works for servers purposes, i.e. in command line mode only, without GUI.

Does fitlet support pfSense?

pfSense is supported and works great on the fitlet.

What are the supported boot modes?

Both UEFI and Legacy boot modes are supported.

How can I monitor CPU temperature in Linux?
