Then, you find its kit with accessories: a VESA mount for placing the NUC on the back of most monitors, various screws for mounting drives, the quick setup guide, warranty and safety information, as well as the power adapter. As you can see, its size is similar to that of a laptop’s power adapter.

The accessories that come with Intel NUC10i5FNH

Unboxing the Intel NUC10i5FNH is quick and painless. The packaging is simple, and it doesn’t come with any premium extras. Inside the box, you find all the accessories you need to set up your new mini-PC and get started right away.

Design and hardware specifications

As all the other devices in the NUC family, the Intel NUC10i5FNH has a functional design. The focus is not on esthetics but efficiency, ease of access, and use. On the front, you see the power button, an audio jack, and two USB 3.1 ports (one Type-A and another Type-C).

On the sides, you see the ventilation grids that help maintain optimal airflow, and on one of them, there is a slot for SDXC memory cards with UHS-II support.

Intel NUC10i5FNH has a card reader too

On the backside of the Intel NUC, there are plenty of ports: three USB 3.1 Gen2 ports (two Type-A and one Type-C), one Ethernet port (at 1 Gbps), one HDMI 2.0b port, the power jack, and a Kensington lock. The size of the Intel NUC10i5FNH is 4.6 x 4.4 x 2 inches or 117 x 112 x 51 mm in width, depth, and height.

Intel NUC10i5FNH comes with a mobile Intel Core i5-10210U processor that is also commonly found on laptops. It has four cores, eight execution threads, a base frequency of 1.6 GHz, and a maximum turbo frequency of 4.2 GHz. An upside to this mobile processor is its low TDP (Thermal Design Power) of only 15W.

The processor inside the Intel NUC10i5FNH

The Intel NUC devices can be equipped with other processors too, like Intel Core i7-10710U or Intel Core i3-10110U. For more detailed specifications and a comparison between all options, go to this page: Intel NUC mini-PCs.

There’s no dedicated video card inside the NUC. All models come with an integrated Intel UHD graphics chip that is suitable for 4K monitors, productivity, and multimedia consumption, but not for gaming or video editing activities.

Intel NUC10i5FNH can be equipped with 16 GB of RAM DDR4-2666 and a 1 TB hard disk. The price changes depending on the hardware components found in your specific model. The unit that we received for testing came with 16 GB of RAM and without a hard disk drive. In the screenshot below, you can see the technical specifications of its RAM. One aspect to keep in mind is that the Intel NUC supports up to 64 GB of RAM, so you can add more if 16 GB is not enough.

The memory used for the Intel NUC10i5FNH

Intel NUC10i5FNH allows users to use one M.2 NVMe SSD drive and two 2.5" SATA III hard drives or SSDs. For more details about the M.2 form factor and NVMe drives, read M.2 vs. NVMe: What is the difference when it comes to SSDs?.

One small downside to the Intel NUC family, in general, is that these mini-PCs don’t have built-in TPM chips for BitLocker system encryption. Some models come with Windows 10 Home preinstalled, and BitLocker is not available for them anyway. The unit that we received for testing did not have a hard disk drive, so we had to install Windows 10 ourselves.

Setting up and using the Intel NUC10i5FNH

Before you can use the Intel NUC10i5FNH, you may need to install a hard disk or some RAM, or both. Accessing its internals is easy. All it takes is loosening four screws that are placed on its bottom.

What is inside the Intel NUC10i5FNH

The slots for adding RAM and storage are easy to access and use. Also, inside the packaging of the Intel NUC, you have all the screws you need. In our review unit, we installed a Kingston A2000 NVMe SSD with a capacity of 500 GB that is capable of speeds of 2200MB/s for reading data and 2000MB/s for writing data.

Adding a SSD inside the Intel NUC10i5FNH

In about a minute, the SSD was installed, and we were ready to go. We installed Windows 10 in just a couple of minutes and then started using the Intel NUC10i5FNH. Its performance was satisfying no matter what we did: web browsing, watching movies, Office work, or running a virtual machine. The Windows 10 startup time was fast (31.3 seconds), in line with many laptops with a similar configuration. Apps were snappy, and the operating system always felt responsive during our days of testing.

As long as we did not stress the processor inside the Intel NUC, there was almost no noise. And even when we stress-tested the CPU, the mini-PC wasn’t louder than what you would hear when using a laptop with similar hardware. One small downside is that Intel NUC10i5FNH is a dust and fingerprint magnet. After just a day of use, it looked like in the screenshot below. If you want it clean and tidy, you may need to wipe it regularly.

We also made a firmware update on the Intel NUC10i5FNH to bring it to the latest version and benefit from the best performance possible before running our standard benchmarks. We enjoyed using the UEFI BIOS of the Intel NUC. It is easy to use, well organized, and good looking.

Updating the firmware on the Intel NUC10i5FNH

One downside to setting up the Intel NUC10i5FNH is that you need to manually install all the drivers by yourself. Without them, you won’t enjoy a bug-free experience, nor the maximum performance available. To make this process easier, it is good to install the Intel Driver & Support Assistant (Intel DSA) and then use it to find, download, and install all drivers for all the Intel components inside the NUC. As you will see for yourself, there are plenty of them, and this is the easiest way to make sure you install everything.

You should use the Intel Driver & Support Assistant

Wireless and Bluetooth connectivity on the Intel NUC10i5FNH are excellent. This mini-PC has an Intel Wi-Fi 6 AX201 wireless network card that works well with the fastest routers on the market. Windows 10 reported a 2.4 Gbps Wi-Fi connection, and we also enjoyed Bluetooth 5 for connecting mobile keyboards, mice, headsets, and more. Since the NUC has only three USB Type-A ports, Bluetooth connectivity may be what you need to connect all the gadgets that you want to this mini-PC.

Overall, we are pleased with the performance offered by the Intel NUC10i5FNH. It is a mini-PC that’s good for everything except gaming, video editing, or computer-aided design (CAD) - tasks that require a powerful video card. If you want more power, there are enough options to choose from, including NUCs with an Intel Core i7 processor. Also, if you want a smaller price, there are more affordable options with an Intel Core i3.

Performance in benchmarks

To get a better understanding of the performance offered by the Intel NUC10i5FNH equipped with an Intel Core i5-10210U processor, we compared it with a desktop PC with an Intel Core i5-10600K CPU and ran several benchmarks. While the components inside this mini-PC are those of a desktop PC, its processor is that of a laptop. Therefore, the key performance differentiator is the processor used inside the NUC that you buy.

First, we benchmarked the Intel NUC10i5FNH using CPU-Z. In the Single Thread test, its processor had an excellent score of 478 points, only 7% slower than the desktop processor we compared it with.

Next, we ran PCMark 10, a benchmark app that evaluates the system’s performance in regular daily activities. That means web browsing, video conferencing, app start-up times, productivity, and digital content creation. Intel NUC10i5FNH had a score of 3896 points, comparable to that of a mid-range laptop manufactured towards the end of 2019 - the first half of 2020.

On the same note – everyday use – we checked how fast the Intel NUC10i5FNH is browsing the web. To do that, we used the JetStream 2 benchmark in Google Chrome, which uses JavaScript and WebAssembly. The higher score you get, the faster your PC is at rendering websites. Intel NUC10i5FNH had a good score, comparable to that of a desktop PC.

To test the temperatures reached by the Intel Core i5-10210U processor inside the Intel NUC10i5FNH, we ran AIDA64’s stability test. The maximum temperature we saw was 90 degrees Celsius (194 Fahrenheit), and the average temperature was around 83°C. While this result is not great, it is not surprising given the Intel NUC’s size and limited cooling. The upside is that the ventilation system is enough to keep the processor below its maximum operating temperature of 100°C, even when under full load.
