40 x 80mm Aluminium Alloy Water Cooling Block

Specifications

• Material: Aluminium Alloy
• Dimensions: 40mm x 80mm x 12mm
• Nozzle Diameter: 7.5mm (Compatible with 7mm-8mm ID tubing)
• Internal Structure: M-shaped flow channel extrusions
• Surface Treatment: Polished contact face for optimal thermal transfer
• Processing: Vacuum brazing for leak-proof performance
• Weight: ~65g

Applications

• PC Thermal Management: Perfect for custom CPU/GPU water cooling loops or cooling M.2 NVMe drives.
• Peltier Cooling (TEC): Specifically sized to cover two standard 40x40mm TEC1-12706 modules for high-power refrigeration projects.
• Industrial Laser Cooling: Maintains stable operating temperatures for high-wattage CO2 or Diode laser heads.
• Power Electronics: Cooling for industrial inverter drivers, motor controllers, and high-power LED arrays.

Unlock New Capabilities

• Past Projects: If you have mastered basic heatsink and fan setups but find your project still overheating or too noisy, it's time to upgrade.
• Feature Upgrade: This water block unlocks the ability to dissipate heat in enclosed spaces (like IP65 cabinets) where airflow is restricted, by moving the heat to an external radiator.
• Effort/Requirements: Intermediate. Requires a 12V water pump, radiator, and silicone tubing. Ensure you use thermal paste between the block and your heat source.

Virtual Technician & Wiring

• Safety Warning: Always perform a "dry run" leak test for at least 30 minutes before powering on your electronics.
• Mounting: Use a mounting bracket or thermal adhesive tape to secure the block. Ensure the surface is clean and flat.
• Flow Direction: The block is bi-directional; however, ensure your pump is rated for the head pressure of your specific loop.

Package Includes:

• 1 x Aluminium Alloy Water Cooling Block (40mm*80mm)

Frequently Asked Questions (FAQ)

• What size tubing fits this water block?
  It uses 7.5mm nozzles, which are perfect for standard 7mm or 8mm internal diameter (ID) flexible tubing.
• Can I use this with a Peltier TEC1-12706?
  Yes, the 80mm length is designed to cover two 40x40mm Peltier modules side-by-side.
• Is the block made of pure aluminum?
  It is a high-thermal-conductivity Aluminum Alloy, optimized for corrosion resistance and heat transfer.
• Does it come with thermal paste?
  No, thermal paste must be purchased separately to ensure the best contact with your device.
• Can I use this for a 3D printer hotend?
  It is generally too large for standard hotends but can be used for custom high-flow cooling builds.
• Is the internal channel a simple hole or a maze?
  It features an internal M-shaped extrusion to maximize the surface area for the water to absorb heat.
• What is the maximum pressure this block can handle?
  It is rated for standard DIY water cooling pumps; avoid high-pressure industrial hydraulic systems.
• Will it rust if I use tap water?
  We recommend using distilled water with a corrosion inhibitor to prevent long-term oxidation.
• How do I secure the tubing to the nozzles?
  While the fit is snug, we recommend using small zip-ties or hose clamps for a leak-proof seal.
• Is the surface flat enough for direct CPU contact?
  Yes, the surface is polished, but high-end PC builders may choose to "lap" it for a mirror finish.
• Can I use this for cooling a CO2 laser?
  Yes, it is commonly used for cooling the mirrors and heads of small to medium CO2 lasers.
• Does it matter which nozzle is the inlet or outlet?
  No, the internal design is symmetrical and works efficiently in either direction.
• Is it vacuum brazed?
  Yes, the parts are vacuum brazed to ensure a single, solid, leak-proof component.
• What is the thickness of the block?
  The main body is approximately 12mm thick.
• Can this be used for car inverter cooling?
  Yes, it is suitable for industrial and automotive inverter cooling within its thermal capacity.
• How do I clean the internal channels?
  Flush with a mix of distilled water and white vinegar if mineral buildup occurs.
