In Win 303 Review

Performance Analysis

The huge vent in the case, relatively powerful, and fairly quiet rear fan, vents in the far side panel, and the comparatively low location of the CPU cooler in the case clearly bolstered the 303's cooling prowess as it managed respectable results in both our graphs. Over our 15 minute stress-test period, there's every opportunity for heat to build up in the case, but with the 303, this would happen well above the CPU cooler position, which sits lower in the case that pretty much any other case we've seen except for inverted or rotated ATX layouts. The CPU delta T of 53°C is a few degrees off the pace of the best results, but was enough to better many cases with more fans and it was 3°C cooler than the more expensive 805 too.


There's less of a spread in our GPU delta T graph, but a result of 49°C is again very good indeed considering there's just one fan dishing out the cooling. Again, the low position of the hardware in the case compared to many other similar cases may help here and the graphics card is also much closer to the base fan mounts too - something we've seen to be beneficial in smaller cases that lack active airflow.


Conclusion

There's a lot to like about the In Win 303 aside from its solid performance in the cooling department for CPUs and graphics cards. It's great to see yet another unique design and for the most part the 303 is also an attractive case with most of the usual mod cons. The exceptions here are the cable routeing and tidying, which could be improved, the side panel can be stiff to remove, there's just a single fan and no fan control, although few cases tick all these boxes.


Aesthetically we grew to like it. It looks clean, the large side window is always a plus and the far panel is interesting too in a space that's often quite bland. Above all we love the internal layout. From the outside it looks unassuming, but the top-mounted PSU and side-mounted fans/radiator will really make it stand out from the crowd. Combined with some handy cooling performance, the 303 is one of the best cases below £100 and it's anything but run-of-the-mill. There are a few caveats, though, which unfortunately prevent us giving it our top award.
