H403 Active Aluminum Heatsink with 4010 PWM Cooling Fan for NVIDIA Jetson TX1 / TX2 Developer Kit

Overview

The H403 is an active aluminum heatsink designed for the NVIDIA Jetson TX2 developer kit. It also fits the Jetson TX1 developer kit, which uses the same carrier board and heatsink mounting holes. It combines a dense-fin aluminum heatsink for passive heat spreading with an integrated 4010 PWM cooling fan for forced-air cooling, keeping the module within its thermal envelope during sustained AI inference and compute workloads—and helping prevent performance loss from thermal throttling.

Installation is a true drop-in job: the heatsink mounts to the four existing heatsink mounting holes on the carrier board with the included screws, the included thermal pad ensures even heat transfer between the module and the flat machined base, and the fan's 4-pin connector plugs straight into the developer kit's fan header—no drilling, no modification, no extra wiring.

Key Features

🔥 Active + Passive Cooling in One Unit

• Passive Cooling: Smooth, straight aluminum fins absorb and spread heat away from the Jetson module.
• Active Cooling: The integrated 4010 PWM fan pushes airflow through the fin array for fast heat dissipation under sustained loads.
• Fewer Throttling Drops: Keeps module temperatures under control during long-running AI and compute tasks, so performance stays consistent.

🔌 4-Pin PWM Fan

• Plug and Play: The fan's 4-pin connector plugs directly into the fan header on the Jetson developer kit carrier board—no adapter or extra wiring needed.
• Smart Speed Control: PWM control lets the Jetson's thermal management adjust fan speed with module temperature.

🛠️ Easy Installation

• Drop-in Mounting: Attaches to the four existing mounting holes on the carrier board with the included screw pack—no drilling or modification.
• Thermal Pad Included: Ships with a thermal pad for reliable heat transfer between the module and the heatsink base.
• Flat Machined Base: Smooth and straight aluminum base ensures even contact with the module.

📐 Compact & Lightweight

• Matched Footprint: 87 × 50 × 20 mm and 60 g—sized to sit neatly on the Jetson TX1/TX2 developer kit without covering connectors or headers.

Installation & Assembly Guide

1. Power off and unplug the Jetson developer kit before installation.
2. If a stock heatsink is installed, remove it and clean any leftover thermal material from the module surface.
3. Place the included thermal pad on the module, aligning it with the heat spreader area.
4. Set the heatsink onto the module, align its four mounting holes with the standoffs on the carrier board, and fasten the included screws evenly in a diagonal pattern. Do not overtighten.
5. Plug the fan's 4-pin connector into the fan header on the carrier board.
6. Power on the kit and confirm the fan spins. Fan speed is managed automatically by the Jetson's thermal driver.
