MONTECH has officially introduced the new KING 45 and KING 15 series, along with their PRO editions and a fresh lineup of cooling fans for an evolved experience of PC building in 2025.
The KING 45 series takes the experience to a full ATX chassis, offering panoramic clarity and top-tier thermal performance for builders who prefer larger systems. Meanwhile, the KING 15 series brings all the good things down to the compact Micro-ATX form factor, designed around a chimney-effect cooling system that optimizes airflow for next-gen GPUs.
Both the KING 45 and KING 15 refine the hallmark panoramic glass from the previous KING 95, reducing its curve from 30° to a sleeker 15° for a cleaner, more modern profile. Inside, an 18% narrower dual-chamber layout conceals cables while maintaining unobstructed airflow and efficient space usage.
MONTECH’s new angled bottom fans are another highlight since they are positioned to pull in more fresh air, keeping the system well-ventilated even during intensive workloads.
Meanwhile, there are the PRO Editions of both KING 15 and KING 45, which are essentially the same but come pre-installed with the new AX120 PRO and RX120 PRO fans, so there’s one less thing to worry about.

Speaking of the fans, the AX120 PRO and RX120 PRO can be obtained separately too, offered in standard blade and reverse blade configurations for one’s existing system, for a nice upgrade to quieter and brighter lit fans.
