Passively Cooled Core i9: Impact Display Solutions IMP-3654-B1-R Mini PC Review

35 W Core i9-9900T in action. Can you run an 8-core 16-thread Core i9 processor with nothing more than a huge heat sink? We stress test the Impact Display Solutions IMP-3654-B1-R mini PC to see just how far we can push the system before throttling begins.

The IMP-3654-B1-B is a fanless mini PC from Impact Display Solutions based on the Kontron D3654-B mini-STX motherboard. It utilizes a large heat sink in lieu of any fans for a completely silent experience not unlike the Zotac ZBox CI660 Nano

More information on the IMP-3654-B1-B can be found on its official specifications page and product page. A list of other mini PCs from Impact Display Solutions can be found here. For this review, we'll be focusing on the performance of the mini PC and how it handles a Core i9-9900T CPU with no fans whatsoever.

Processor

We're able to assess CPU performance over time by running CineBench R15 Multi-Thread in a loop. Performance remains stable at a score of about 1100 points until an abrupt drop to 390 points as shown by the chart below. Unusually, performance would spike back up again to normal towards the end of the test. We explore this phenomenon further in our Stress Test section.

GPU Performance

Intel's UHD Graphics series is years old and outdated as of 2020. Users looking for more integrated graphics power should consider the Iris Plus or competing RX Vega series instead which can offer nearly two times the performance at the same thermal envelope or lower. For standard web browsing and 4K playback, however, UHD Graphics will be sufficient. We're not able to record any dropped frames when playing our one-minute 4K UHD YouTube test video.

Emissions

Temperature

We're able to record surface temperatures just under 30 C when idling on desktop for just over an hour. When under maximum processor stress, the large heat sink can become as warm as 43 C to 53 C as shown by our temperature maps below. The right side of the mini PC will be noticeably warmer than the left due to how the CPU is positioned underneath. Of course, it's not recommended to place any books or novelties on top of the system which owners of other mini PCs may do.

Because of the throttling behavior of the system, however, surface temperatures will eventually fall and stabilize from the aforementioned 53 C to just 39 C.

Stress Test

We stress the mini PC with synthetic loads and monitor system vitals with HWiNFO to identify for any potential throttling issues. When running Prime95, CPU clock rate will boost up to 2.6 GHz for about 20 seconds before falling slightly to the 2.3 to 2.4 GHz range. Core temperature would slowly rise until hitting 67 C where clock rates will then plateau down to just 800 MHz for a cooler core temperature of 48 C. Similar results can be observed when running CineBench R15 Multi-Thread in a loop; clock rates will run at about 2.5 to 2.7 GHz until hitting a temperature ceiling of 79 C. Thereafter, clock rates will fall to just 800 MHz in order to maintain a cooler core temperature.

Energy Management

Power Consumption

Idling demands between 6 W and 9 W to be very similar to what we recorded on the latest Intel Frost Canyon NUC. Running more stressful loads like 3DMark 06 will draw upwards of 46 W.

We're able to record a maximum draw of 69.7 W from the small (10.5 x 4.5 x 3 cm) 65 W AC adapter after initiating Prime95. However, this high of a consumption lasts for only 20 seconds before falling slightly to 64 C as shown by our graphs below. The initial boost corresponds with our Prime95 stress test observations above where the maximum clock rate of 2.6 GHz was also only attainable for about 20 seconds.

If CPU clock rates throttle to 800 MHz as mentioned earlier in the review, power consumption will fall even further to just 28 W.

In review: Impact Display Solution IMP-3654-B1-R Mini PC. Test unit provided by Impact

Can the Impact IMP-3654-B1-R Mini PC run a Core i9 CPU with just a heat sink? The answer is yes, but it's only for a limited time. When the system is fully stressed for long periods, clock rates will eventually throttle and fall off a cliff as we've demonstrated above in multiple instances. At its best, clock rates will stabilize at around 2.5 GHz for an overall multi-core performance level similar to the 45 W hexa-core Core i7-9750H even though the Core i9-9900T is a 35 W octa-core part. This is one of the fastest silent mini PCs you can find in that regard.

If you don't plan on running extreme processing loads for extended periods and only want the occasional boost in performance from a Core i9 CPU, then the silent IMP-3654-B1-R Mini PC should fit the bill. A Thunderbolt 3 port or SD reader would have expanded the versatility of the mini PC.

After graduating with a B.S. in environmental hydrodynamics from the University of California, I studied reactor physics to become licensed by the U.S. NRC to operate nuclear reactors. There's a striking level of appreciation you gain for everyday consumer electronics after working with modern nuclear reactivity systems astonishingly powered by computers from the 80s. When I'm not managing day-to-day activities and US review articles on Notebookcheck, you can catch me following the eSports scene and the latest gaming news.
