Phanteks XT M3 micro tower wit

The XT M3 is a compact Micro-ATX gaming chassis designed to support powerful yet space-efficient PC builds. It features multiple fan mounting positions, including a dedicated 360 mm radiator location at the top and triple 120 mm fan mounts at the bottom for direct GPU cooling. The case combines a clean, minimalist exterior with an internal layout focused on effective airflow and neat cable routing, and it is compatible with rear-connect mainboards.

Advantages

The chassis supports up to nine 120 mm fans and offers a top-mounted 360 mm radiator area, providing extensive cooling options for high-performance components. Bottom triple-fan locations enable targeted GPU cooling. A spacious cable routing area helps maintain an organized build, while the tempered glass side panel allows for a clear view of internal components. The XT M3 accommodates both microATX and Mini-ITX motherboards.

Suitable for

• Compact gaming PCs using microATX or Mini-ITX motherboards
• High-performance builds that require extensive fan or liquid cooling (360 mm top radiator support)
• Systems where direct GPU cooling is desired (triple 120 mm bottom fans)
• Clean, showcase builds using a tempered glass side panel

How to use

Install a microATX or Mini-ITX motherboard and arrange components to maintain clear airflow paths. Mount up to nine 120 mm fans in the available positions, placing a 360 mm radiator at the top if using liquid cooling. Use the triple bottom fan mounts for direct GPU cooling when needed. Route cables through the spacious cable management area behind the motherboard tray to keep the interior tidy and unobstructed.

Recommendations

For optimal cooling performance, combine top radiator placement with bottom fan mounts to create a balanced airflow pattern. Use high-quality thermal paste and ensure fans are configured for intake and exhaust according to your cooling setup. When installing multiple drives, check clearance against installed cooling hardware and the GPU length.
