NZXT H5 Flow RGB Black Mid Tower PC Case Review

Complete System

It’s not surprising that this was a very easy build process, as it’s a high-end case, with premium build quality and a fairly standard layout with plenty of space for cable routing and cooling. It just looks great, and what’s more, it was a very easy build too.

The cable management behind the motherboard is awesome, with systems in place to deal with cables going in any direction so that the cable runs are kept nice and short in the main chamber of the case.

I do wish it had a vertical pass-through for the GPU cable though, I wish all cases did, but it’s not really a deal breaker either, as cables can still be routed neatly enough here.

GPU size is good too, there’s room for a card of up to 365mm, so even the largest RTX 4090, the AORUS Extreme which measures 358.5mm will fit, but it’ll likely be a hard time getting it installed in the first place, but it should fit! However, if you stick a radiator in the front, that’s obviously going to eat into the available space, so be sure to work it all out ahead of time.

The case comes with two F140 RGB Core (Case Version) fans, which run at 120 to 1200 RPM, and they’re superbly quiet and capable of moving plenty of air too (61.74 CFM each). The rear fan is an F120Q but also runs at the same 1200 RPM.

However, if you do want liquid cooling, you can install a 280mm radiator in the front, 240mm in the top and 120mm in the rear. If you wanted to stick with air cooling, it’ll take a 165mm tall CPU cooler, which is the exact amount of space needed for a Noctua D15S, and that’s one of the biggest on the market, so anything else should be fine.

Overall, it scores top marks, and with two fans in the front, one in the rear, the top mesh, and the bottom shroud intake fan helping direct the airflow through the case, it runs cool and quiet too.
