Test Setup

Professional testing requires the emulation of real-world situations but with repeatable results; thus, a perfectly controllable test setup and environment are required, especially for comparable results. Testing the thermal performance of any case with a typical real-world setup technically limits the comparability of the results to this setup alone, as an active system interacts with its environment and the change of a single component would alter myriads of variables. As such, we developed synthetic loads that emulate the thermal output of real systems, which however are passive, steady and quantifiable. As such, the thermal testing now displays the thermal capabilities of the case alone, as if it would have to deal with the entire thermal load by itself, regardless of the system that would be installed inside it. Laboratory data loggers are being used to monitor the PT100 sensors and control the safety relays, which are fully accessible via our custom software. Three such loads have been developed; the ATX version simulates a 200W CPU, 50W VRM, 30W RAM and 4 × 120W GPU card thermal load. Finally, three 3.5" HDD dummy loads have also been created, with each of them converting 30 W of electrical power to thermal, bringing the total thermal load of the ATX test setup up to 850 Watts. As such, the thermal load is immense and only the best of cases will be able to handle it for more than a few minutes, we are also performing a test with a thermal load of 400W, with all of the aforementioned components except the HDD drives at about 42% power, which is more suitable for the majority of cases.

Noise testing has been performed with a background noise level of 30.4dB(A). Advanced noise testing is also being performed, in order to assess the ability of the case to dampen the noise of the components installed inside it. This includes the installation of two noise-generating sources (strong fans) inside the case, one positioned approximately over the first expansion slot and one over the CPU area, which generate ≈ 44.2 dB(A) when unobstructed. During the advanced noise test, all stock cooling options of the case are entirely disabled.

Note: Due to the nature of the Streacom case's design, the three 3.5" dummy thermal loads were installed to the right of the case, near the front panel, vertically.

Results & Discussion

Thermal testing is usually performed with the stock fans of the case operating at maximum speed. However, the Streacom F12C does not have a single fan installed from the factory. This creates a small impasse, as our thermal load is passive and completely depends on the thermal dissipation capabilities of the case itself. Without any fans, the Streacom F12C depends on just natural air convection. However, a thermal load of 850 Watts cannot be effectively dissipated without any active cooling from the case.

400 Watt Test - No fans installed

As we always test cases with just their stock cooling solutions, we tested the Streacom F12C without any fans installed. The case, as displayed in the graph above, could only handle the reduced thermal load of 400 Watts. If compared to a typical case with active airflow, the F12C would appear far worse. It actually is inferior to a basic Midi-ATX tower case, such as the BitFenix Neos. Still, considering that there was no active airflow, that the F12C could handle a thermal load of 400 Watts is an impressive result.

However, since the F12C is a very advanced (and expensive) case designed to hold very powerful ATX system, we felt that we should also test it considering the presence of fair airflow. As such, we installed three Corsair AF120 fans for a second series of tests. We installed two fans to the left side of the case, as an intake, and one at the middle of the top mounting braces, as an exhaust.

The inclusion of the three cooling fans worked miracles for the thermal performance of the Streacom F12C, which can now compete and even surpass good tower cases. The positive pressure created by the two intake fans pushes the warm air out from the many openings of the case, while the top exhaust fan extracts hot air from the core of the thermal load. With the added airflow, the F12C competes with large tower cases, such as the XFX Type 01, and faces even the SilverStone Fortress FT05, a case with massive stock fans.

As the Streacom F12C has no stock cooling at all, we obviously could not perform any stock acoustics testing either, since there is no noise source. The noise of a finalized system will solely depend on the parts chosen by the user. We had to skip directly to our advanced noise testing, exploring the noise dampening capabilities of the case. Simply put, the Streacom F12C has no such capability at all. Our instruments measured almost the same sound pressure generated by the dummy noise source with it inside the case, i.e. 43.5 dB(A). That is a mere 0.7 dB(A) reduction, an entirely imperceptible difference for any human ear.

    Sorry, lost a sentence there.

    You may be right about dB(A)/W (although it does not work quite that way) but it is not useful to provide noise graphs for three specific fans that I chose for a test that was done just for illustrative reasons. If I chose two fans, four fans, or any other fans from the hundreds of the available models, the results would differ. There is no point to provide you with a "dB(A)/W" rating when that will change based on your selection.

    Caveat. I've used their SFF passive case (8c) in the past. These are rated upto 95W TDP hardware, however, even using 65W TDP, cpu and mobo temperatures crept up to around 60°C, and I wasn't even pushing the hardware very hard.
    Using a 45W TDP unit in it's current incarnation keeps temps generally around 45°C, every once in a while it goes up to 50.

    I also use a SFF an active unit (7C), and, using a 65W TDP unit, it can't keep the unit cool when only the CPU fan is installed. There is not evough room inside the case to use anything but a low profile fan, and it needs help from a small (size limit again) evacuation fan. This works, but the noise at load is quite horrendous.

    So far I have NOT been impressed with Streacom efforts.

    It doesn't look very attractive to me, but I think a person with some talent doing some slight mods can make it look nice. But default it just looks bad to my eyes.

    Interesting, but some very strange decisions here; while I like that there's an option for using the sides as intakes/exhausts, I can't help but feel that the case should still have mounts for a more traditional front to back cooling setup with vents for intake fans at the front, since this is the only side that should be completely clear at all times. The sides and top could easily be obstructed in many HTPC setups, which limits the usefulness of a case that can only be cooled from these sides. While I don't like using the rear panel for exhaust due to the necessarily small fan mounts (once you take up space for PCI slots and I/O), not offering it as an option still seems a glaring mistake.

    Likewise the lack of front USB ports; that limits its usefulness for gaming (nowhere to plug in wired controllers or charge wireless ones) and eliminates a useful means of connecting install media or providing media files that you already have.

    So yeah, as much as I like well made aluminium cases, there are just too many issues with this one to make it really useful IMO.

    I rather think it's a nice htpc case. I currently use a node 605 and if I had silver components id rather have this. All I need in an htpc is a very good looking case about the same width as my amp and space for a full size vide card. Optical drive? I can rip to my nas from the nas itself or my desktop, or my laptop. Tuner? HD homeruns in the garage. USB in the front is an affront to the senses especially with the blue plastic in 3.0 ports. I just run an active USB repeater cable to a pop up panel in the floor and a coupler into the leg of the coffee tabletable to a popup panel. Htpc controls are via a mce receiver in the back with a harmony ir blaster. Some people just want things to look clean. They should offer 19" rack mount ears to go all the way for custom installs.
