Xhuttle Top Fan Installation

To optimize thermal performance for high-performance GPUs in the Xhuttle chassis, installing top-mounted fans is strongly recommended. The chassis supports up to three 120mm fans at the top panel, designed to exhaust hot air passively from the GPU area. Without adequate airflow, heat accumulation at the GPU’s upper section.

• Fan Size: 120mm (standard)
• Installation Positions: 3 pre-configured slots 

Installation：

Triple-Fan Setup Top Fans Position 1&2 :

• Maximizes heat dissipation for intensive workloads.
• Note:  will partially block the GPU’s rear I/O ports (HDMI/DP).

Dual-Fan Setup Top Fans Position 3:

• Ideal for initial testing to evaluate cooling performance or general use.
• Provides balanced airflow without obstructing GPU I/O ports.

Critical Pre-Installation Steps for Triple-Fan Setup

• Use Angled Cables: Install 90-degree angled DP/HDMI cables before mounting the Triple-fan Setup. This prevents port obstruction and ensures cable accessibility.
• Verify Clearance: Confirm that the fan does not physically interfere with the GPU’s backplate or power connectors.

Special Considerations for  5090-Series GPUs
For high-power GPUs like the NVIDIA 5090 series, consider upgrading to 30~35mm-thick high-static-pressure fans to improve heat extraction.

• Clearance Constraints:

  • The total vertical space between the GPU and chassis top panel is 57-58mm.

  • A 35mm-thick fan occupies approximately 60% of this space. Ensure the remaining clearance accommodates the GPU backplate and angled cables.

• Mandatory Angled Cables:

  • Always pre-install 90-degree angled DP/HDMI cables before mounting thick fans. Standard cables may protrude and collide with the fan frame.

• High-Speed Display Output Considerations for Premium GPUs

  • When using high-end GPUs (e.g., NVIDIA 5090 series) with demanding display configurations (e.g., 4K/8K @ 120Hz+ or HDR), ensure uncompromised signal integrity for DP/HDMI interfaces by using certified ultra-high-speed cables.
