GMK NucBox 3 review: Fanless Windows 11 HTPC

Compact and silent, but at what cost? The Celeron J4125 may be getting a bit old, but its low power requirements can allow for both a slimmer chassis profile and fanless design to be attractive for HTPC users. Unfortunately, performance isn't where we would like it to be even for undemanding HTPC loads.

Unlike the tiny NucBox S or more traditional NucBox 2, the NucBox 3 is a fanless design utilizing the same Celeron J4125 processor that powers the original NucBox S. The system was made for HTPC environments and other low-power applications where silent operation takes precedence over raw performance.

Note that the NucBox 3 isn't necessarily better or faster than the NucBox 2 or NucBox S despite what the naming convention may suggest. Instead, the NucBox 3 has different advantages and disadvantages from its two siblings that may appeal to different users. They may, however, share similar materials.

Competitors to the NucBox 3 include other fanless mini PCs such as the Zotac CI Nano series or the Chuwi GBox. The unit with 8 GB DDR4 RAM and 256 GB SSD storage currently retails for about $269 USD on Amazon (or $219 after coupon) or $309 through the manufacturer.

Case

The materials and overall shape of the NucBox 3 are similar to the NucBox 2 even if their dimensions are different. The top of the unit, for example, continues to be glossy fiberglass while the edges and corners are matte. Chassis rigidity is satisfactory, but expect fingerprints, dust, and scratches to build up on the glossy top very quickly.

Connectivity

Port options are respectable save for the lack of a USB-C port. Additionally, the HDMI 1.4 port is limited to 4K at 30 Hz meaning it's highly recommended to use the DisplayPort instead if connecting 4K monitors.

Communication

Transmit speeds are slower than expected even for an older Intel 7265 WLAN module. Users will more than likely be streaming content to the unit instead of from the unit, however, and so the poor transmit speeds shouldn't be an issue for most applications. The gigabit RJ-45 port is always available for faster network performance if desired.

Maintenance

The bottom panel is secured by just one Philips screw for easy access to the single SODIMM slot and M.2 2280 SATA III bay. Dual-Channel RAM is not supported.

Accessories and Warranty

There are unfortunately no extras in the box other than the AC adapter and paperwork. A mounting bracket, for example, is not included whereas it is usually standard on competing mini PCs including those from Beelink.

Performance

Testing Conditions

Our unit was set to Performance mode prior to running any benchmarks below for the highest possible scores.

Processor

CPU performance is roughly 10 to 15 percent slower than the average PC in our database equipped with the exact same Celeron J4125 processor. The CPU is fortunately still ahead of any Atom CPU thus far by wide margins.

System Performance

Windows 11 runs very slowly on the NucBox 3. Simple actions that are normally instantaneous on other PCs like opening file explorers, small files, or even clicking the Windows Start icon all have noticeable delays to them on the NucBox 3. We find the slow navigation to be tolerable for light browsing or word processing, but you're going to want something faster for any sort of active multitasking.

DPC Latency

LatencyMon shows DPC issues when opening multiple browser tabs on our homepage. 4K video playback at 60 FPS is generally ok but not perfect as we're able to record 13 dropped frames during our minute-long video test. CPU and GPU utilization each hover at around 50 to 60 percent when under such conditions.

Storage Devices

There is just one internal storage slot and it is compatible with M.2 SATA SSDs only. The 256 GB Netac drive on our unit would return mediocre read and write rates of around 300 to 500 MB/s each. The drive appears to have trouble maintaining its maximum performance for long periods when running DiskSpeed in a loop.

GPU Performance

Graphics performance is poor and unfit for any sort of gaming as the UHD Graphics 600 is much slower than the common UHD Graphics 620. The NucBox 3 is instead better for streaming purposes.

Surface temperatures are generally warmer than on most other mini PCs since the NucBox 3 has no internal fan. When running high loads for extended periods, the top surface can be as warm as 50 C compared to only 30 C on the Beelink GTR5. You'll want to be mindful of any items or books placed on top of the GMK mini PC.

Stress Test

The CPU stabilizes at 37 C when idling on desktop with no running applications. When running Prime95, CPU clock rates would boost to 1.7 GHz for a few minutes until eventually stabilizing at 1.4 GHz and 85 C. This core temperature under load is warmer than on most other mini PCs since our NucBox 3 is fanless. The higher-than-average CPU temperature would also explain the higher-than-average surface temperature noted above.

CPU package power would boost to 13 W during the start of the test before quickly stabilizing at the 8 to 9 W range.

Power Consumption

As expected, the NucBox 3 is very power efficient and less demanding than many of its alternatives including the Beelink U59 or Chuwi LarkBox. Idling on desktop draws just 3 to 4 W while higher loads tend to average around 11 W. Consumption can spike up to 25 W when under extreme loads albeit for only a few seconds at most due to the limited Turbo Boost potential of the processor.

Prime95 stress would cause power consumption to spike to 19.3 W temporarily before falling and stabilizing at 10.5 W

Verdict

In review: GMK NucBox 3. test unit provided by GMK

On paper, a slim, inexpensive, and fanless HTPC with 4K video playback capabilities should be ideal for just about any home theater setup. The silent NucBox 3 has certainly nailed the low price and inconspicuous profile, but performance is barely sufficient if not lacking even for the most basic of HTPC tasks. The latency, frame skips, and extended loading times are tough sacrifices for a fanless PC. For "set it and forget it" scenarios, however, the slow performance will be less of an issue.

Its very low price is the most attractive aspect of the NucBox 3. Potential owners should be aware of the overall slow system performance that entails.

Fanless mini PCs with faster CPUs and performance are available such as the Zotac ZBox CI622 Nano with a 10th gen Intel Core i3 CPU. It'll cost a bit more, but it may be worth considering if you plan on using your HTPC frequently.

Price and Availability

The NucBox 3 is now widely available through Amazon or directly from GMK for $310 USD or less.
