Cowcotland: the Iron Glass, “almost high-end” and very quiet

The Iron Glass is an E-ATX full tower weighing 11.9 kg, offered in a single shade, Gun Metal. Its front carries abrushed aluminium plate; both sides are hinged smoked tempered glass doors, which swing open like shutters to reach the components.

On top, the Power and Reset buttons are aluminium, next to a USB Type-C port, two USB 3.0, one USB 2.0 and the audio jacks. Four 120 mm dual-ring ARGB fans are supplied, driven by a controller hidden behind the motherboard tray and a remote control. Cowcotland also recalls having "loved" the Elite White, tested there before this one.

Cowcotland measures the noise of every case in the same room, with fans at full speed. On the same set of measurements, the Iron Glass ranks as follows:

• G300A : 46.3 dB(A)

• SETA D1 : 39.9 dB(A)

• M.RED Iron Glass : 36.8 dB(A)

• AX-90 : 34.6 dB(A)

The downside is a familiar one: its solid front panel lets in less air than a mesh one. Temperatures remain decent — 70 °C for the processor under load, 72 °C for the graphics card at full speed — but one to three degrees above the best in the comparison, without the gain you would expect from four fans. That's the "almost" in the title.
