CONCLUSIONS
The SilverStone SG15 has easily accessibility to internal hardware as the top, bottom and side panels are easily removable.The case feels premium and well made, and it’s not too big at 19L in volume. Hardware compatibility is excellent in some area’s, and not so good in others.
Air cooling the CPU is where the SG15 fell short in our opinion, due to the limitations it causes and incompatibility with popular air coolers such as Noctua’s D15 and C14S.
The SG15 does support the Noctua U12A and D15S, but these comprises the use of the rear, top and one side panel fan. This leaves only one intake fan on the side panel. We wouldn’t recommend air cooling the SG15 as it just feels like an unjustice; giving the limitations mentioned. This doesn’t mean it performs poorly if you go with an air cooled system. It’s just not the best solution for the case.
AIO liquid cooling the CPU is where the SG14 & SG15 really shine. We recommend using a 240mm side mounted radiator. AIO pump block height is limited to 55mm if you want to use both 120mm fans on your AIO cooler.
You can then install top 120mm fan for extra intake or exhaust and still have ability to install 120/140mm rear exhaust fan. Our recommended configuration is 240mm AIO, top 120mm intake fan and 140mm rear exhaust fan.
The power supply can be orientated in both directions to either exhaust hot air from the GPU or the AIO. In our opinion, you likely better off using the PSU as GPU exhaust if your GPU features pass through cooler design.
If your going to be using an AIO and thick boy GPU or any combination of the two, then you won’t be disappointed with the SG15. If air cooling is your jam, we wouldn’t 100% recommend using this case due to its drawbacks.
Unfortunately, there’s no one or two solutions to make everything work well in the SG15. What was certain for us, is that ATX PSU support is unnecessary, especially when it compromises more important aspects of the case such as CPU cooling.
There is central divider attached to the PSU cage/bracket that can interfere with some CPU coolers and just makes everything unnecessary squeeze on the motherboard side. This divider also acts as 2.5″ drive mount which again is way less necessary that ease of you and cooler compatibility.
