With the frame removed, we can have a closer look at the interior design of our Antec ISK 310-150. The PSU is shaped originally. It is compact in its main part but expands to accommodate a larger fan. A special feature of this computer case is that it allows installing a second exhaust fan.
There’s a piece of plastic instead of the missing 80mm fan to protect the interior against dust.
There are places for two fan speed controllers on the back panel, but only one controller is actually installed.
This controller is part of the preinstalled TriCool series fan. So, if you want to improve ventilation by installing a second fan and want to regulate both fans manually, you should look for appropriate models in Antec’s line-up.
The assembled Antec ISK 310-150 is very cramped. With the components placed so densely, some cables may get stuck between the blades of the CPU cooler. So it is important that you use cable straps to remove them as far away from the cooler as possible.
When this problem occurred during our tests and the CPU cooler’s fan stopped, the CPU eventually got as hot as the permissible maximum of 85°C and dropped its clock rate and, consequently, performance.
There is one more shortcoming that must be noted. The HDMI port of our discrete graphics card was partially blocked by the back panel of the chassis.
The photo above shows you the reason for that problem. It is due to the expansion card’s pivoted fastener. The mounting holes coincide but the card’s PCB is slightly bent.
Save for the mentioned downsides, we had no problems assembling our testbed configuration in this computer case.
The preinstalled 80mm fan works at 1075 RPM in the low mode, 1750 RPM in the medium mode, and 2740 RPM in the high mode. The fan is silent at the low speed, barely audible at the medium speed (it is no louder than the PSU’s fan then), and only becomes uncomfortable at the high speed.
The assembled Antec ISK 310-150 looks elegant and imposing, notwithstanding its tiny size.
- Robust and rigid chassis
- Very compact dimensions
- Quiet at low and medium speed of the preinstalled exhaust fan
- Allows installing an additional fan
- Excellent exterior design
- Poor design of the expansion card fastener
- Cables may get stuck in the blades of the CPU cooler’s fan
- High price
