MONTECH has just unveiled a new line-up of PC cases, the KING Series, which includes the KING 45 and KING 15 models, along with their respective PRO versions. These cases aim to blend high-end aesthetics with smart cooling design, featuring a distinct curved, panoramic glass panel to show off your build. To complement the new cases, MONTECH is also releasing the AX120 PRO and RX120 PRO cooling fans.
KING 45 and KING 15 Cases
The core of the KING Series design is the curved glass, which offers a virtually uninterrupted, panoramic view of all your internal components. It’s a design choice clearly intended to let builders showcase their efforts.
Inside, the cases feature a dual-chamber layout. This is a great design choice for keeping things neat, as it effectively hides your power supply unit and cables in a separate compartment. This separation also helps with airflow efficiency, making sure that the main components get unrestricted cool air.
A key focus for MONTECH with these cases is cooling, particularly for modern, power-hungry GPUs. They’ve incorporated an innovative airflow design:
- Angled bottom fans are designed to channel fresh air directly up and onto your graphics card.
- This creates a Chimney-Effect Cooling system, pulling heat directly off the oversized GPUs and exhausting it upwards, which helps to maintain lower core temperatures for better, more sustained performance.
The KING 15 and KING 45 differ mainly in size, giving you options depending on the scale of their planned system.
The PRO Difference and New Fans
For those seeking an out-of-the-box premium experience, the KING 15 PRO and KING 45 PRO editions come preinstalled with MONTECH’s brand-new AX120 PRO and RX120 PRO fans. These new PRO fans are designed to provide both visual flair and superior cooling performance.
- The RX120 Pro features a reversed fan blade design, which is great for ensuring a consistent look and good thermal performance when used as intake or exhaust in different mounting positions.
- They boast dynamic 360° ARGB lighting on both the fan frame and the blades.
- MONTECH claims these fans deliver 10% more airflow thanks to optimised blade geometry, ensuring high-performance cooling with quieter operation.
The AX120 PRO and RX120 PRO fans are also available for purchase separately.
What We Think
The new MONTECH KING Series looks like a fantastic both from a. The curved glass is undeniably striking and will be a major selling point for those who treat their PC as a piece of art.
More importantly, the focus on efficient cooling, especially the angled bottom fans and the chimney effect. With modern graphics cards generating so much heat, a direct, dedicated airflow path is crucial. The dual-chamber design is a great feature for achieving that sleek, professional finish without making cable management a nightmare. The inclusion of the new AX/RX PRO fans in the premium models is a nice touch.
