Fanless PC components …
The Streacom FC8 Alpha case is tested with the following components:
Streacom Nano160 power supply
ASRock Z270 Gaming-ITX LGA1151 motherboard
Intel Core-i5 6600K CPU
2x 8GB Crucial DDR4-2666 RAM
Crucial M550 M.2 SSD
The following tools were used: Prime95 V28.10 and 3DMark 2.3.3693
Fanless PC Motherboard …
At this point we want to show step by step a completely Silent ITX HTPC Tutorial and what would be better as the just presented ASRock Z270 Gaming-ITX/ac LGA1151 ITX motherboard?
Fanless PC SSD …
Before we install the motherboard into the case, we’ll install a Crucial M.2 SSD at the flip side of the motherboard. In addition we need to stick some buffers on the nuts – that is a little boring – but necessary for the later installation of the CPU cooler.
Now we install the I/O shield and the motherboard.
Fanless PC CPU cooler …
There is now some tinkering, because we build with the enclosed items …
… a CPU cooler. First the heatpipes should be installed loosely without thermal paste in the cooler …
… then take measure inside of the chassis, and now equip with heat-conductive paste and screw properly. Because only so you can locate the correct spacing of the four heatpipes. A little thermal compound is applied on the outside of the heat pipes, in the lower CPU cooler part and of course on the CPU during assembly. Then, the three connection blocks are screwed from the outside through the same cooling fins.
Fanless PC CPU and memory …
For testing we have by the way installed an Intel Core-i5 6600K CPU and 8GB Crucial DDR4-2666 memory modules.
Fanless PC Power Supply …
Now we come to the power supply, which must be acquired separately. We have decided for the 160 Watt Streacom Nano160 PSU.
160 watts sounds not much, but it is more than enough for common CPUs. Only for the graphics card we have to do unfortunately smears, because the NanoPSU power supply has no graphics card connection. So for example you can install one Low Profile GeForce GTX 1050 Ti *Ad graphics card in the ITX chassis. Also, you should take care about the maximum output power at 12V 8A, 5V 6A, 3.3V 2A, +5VSB 1A and -12V 0.02A and a total output of 160W.
Fanless PC Graphics card …
For our HTPC build we have dispensed the graphics card and decided us for an Intel Core-i5 6600K processor with integrated GPU. Here you can see the finished installation of the Nano PSU, more specifically the DC/DC converter on the 24 pin ATX connector with 2x SATA, 1x Molex and 1x 4-pin CPU cable.
Now organizing the cables a little bit …
… and already the retaining plate for the drive can be mounted. Anyone who like to install a HDD, can screw the 3.5″ hard drive below and to install up to two additional 2.5 inch SSDs. Alternatively one can mount an optical slimline slot-in drive in the Streacom FC8B-OPT-ALPHA. And what you also should remember for the HTPC is the remote control. To remote control the PC we’ve published already numerous IR receiver instructions such as USB Ultra IR v2.0 guide along with IR receiver kit.
As mentioned previously, not the small Nano converter board is the actual power supply, because it must be connected now outside of ITX chassis. According to a consultation with the manufacturer, there are currently no internal power supplies available for this case. So the power supply and the WiFi antenna stay outside the enclosure.
Power on the quiet PC …
We come now to the most exciting moment of this fanless Media PC guide and turn the ITX PC on, then nothing, absolutely nothing to hear … pretty strange, if you hear nothing, no fan, no whirring hard drive!
An absolutely silent PC! This is what we like to hear from a PC in the living room!
Fanless PC temperature and HTPC power consumption …
Then, we want to clarify the question if the cooling concept works and will do different measurements. Thereby, we want to see how much power consumption is, because this is also an important thing for a HTPC.
| Temperature and power consumption of the fanless ITX PC |
|||
| Load | CPU temperature | Motherboard temperature | Power consumption |
| Standby | – | – | max. 1.6 Watt |
| Idle | 36°C | 43°C | max. 19.5 Watt |
| 3D Mark | 50°C | 47°C | max. 65.1 Watt |
| Prime95 | 74°C | 56°C | max. 76.7 Watt |
Disadvantages can have advantages, because the idle power consumption of the tiny Streacom Nano160 power supply unit with 160 Watts is much lower than with an bigger size 500 Watt power supply.
And as you can see very nice, the Streacom FC8 Alpha chassis cooled the installed Intel Core-i5 6600K CPU with 91W TDP correctly even with longer load of 3DMark. Only a few hours of Prime95 housing with this CPU heat fanless ITX clearly.
Here you can see a BIOS screenshot of PC health menus.
And because we want to offer even more service to our readers, we have done some very interesting thermal pictures. Here you can see the closed Streacom FC8 Alpha ITX case from above – the heat distribution was like to be expected, …
… because we have measured the highest temperature by up to 54.1°C between the cooling fins of the fanless ITX chassis.
Here you can see very nice the heat distribution inside of the case: The VRMs together with the DC-DC converter of the Nano PSU have the highest temperature and heat of the CPU is transferred reliably over the four heatpipes on the cooling fins of the chassis.
